Build and own the agent execution runtime and connector framework, develop operator-facing interfaces, and implement data pipelines for autonomous security assessments. | Requires a bachelor's degree, at least seven years of professional software engineering experience, and demonstrated expertise in distributed systems, GraphQL APIs, and production React/TypeScript applications. | Get to Know Us Horizon3 is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find, fix and verify exploitable attack vectors before criminals exploit them. Our flagship product, the NodeZeroTM platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises. It is used by IT Ops/SecOps teams, consulting pentesters, and MSSPs and MSPs. We are a fusion of former U.S. Special Operations cyber operators, startup engineers & operators, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools and false positives, resulting in alert fatigue, blind spots, "checkbox” security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants. Collectively, we are a team of learn it alls, committed to a culture of respect, collaboration, ownership, and results. What You'll Do As a Senior Full-Stack Engineer on the Autonomous Defensive team, you'll build the platform that NodeZero's defensive agents run on. Our AI researchers define what these agents should reason about, you build the systems that make that work in production, across thousands of customer tenants, without breaking anything. That means real distributed systems problems, not glue code. They execute inside customer environments under tight isolation, credential, and egress constraints. And when an agent proposes a change in production, the platform has to be able to simulate it, stage it, gate it on approval, roll it back, and prove after the fact exactly what happened and on whose authority. It also means the interfaces that sit on top of all of that. Autonomous systems are only trusted to the extent that people can see what they did and intervene before they do it, and that burden lands on the front end. These surfaces are part of the product, not a thin layer over the API, and you'll own them end to end alongside the backend they talk to. This is a platform role. You'll own the runtime, the tool layer, the orchestration, the connector framework, and the observability and UI that make agent behavior debuggable. We're looking for engineers with strong backend depth who are comfortable building the front end when the workflow demands it — not because it's beneath them, but because they understand the value of end-to-end delivery. You'll work closely with our AI researchers, but you are not being hired to tune prompts — you are being hired to build the substrate that makes their work shippable and safe. Responsibilities Build and own the agent execution runtime: durable, resumable, long-running workflows with checkpointing, idempotent steps, cancellation, and timeouts at both the step and run level. Design and implement the tool layer that agents act through — a registry with versioning, schema validation, per-tenant enablement, and authorization enforced server-side rather than by the model. Build the connector framework for third-party security control planes (EDR, firewall, identity, SIEM, cloud IAM). Implement the safe-change pipeline: dry-run and simulation, blast-radius classification, approval gates for high-impact actions, staged rollout, rollback, and an immutable per-tenant audit trail. Build the operator-facing front end in React and TypeScript, turning dense system state into interfaces a user can reason about and act on with confidence. Build the client-side data and streaming layer that keeps those interfaces accurate against long-running, incrementally updating state, over WebSockets rather than polling. Extend NodeZero's tenant isolation model to agents that take write actions, covering execution boundaries, egress control, quotas, and cross-tenant leakage in caches, indexes, and logs. Develop core product features in ETL and GraphQL to support data processing and retrieval for agent context, run history, and remediation state. Build the ETL pipelines that turn pentest and remediation outcomes into the datasets our researchers train and evaluate against. Instrument everything. Distributed tracing across an agent run, cost and token accounting per tenant, and the tooling to answer "why did the agent do that" without guessing. Partner with AI researchers, attack engineers, and product to take capabilities from prototype to production, and feed platform constraints back into research direction early rather than late. Required Education / Experience Bachelor's Degree in Computer Science, Computer Engineering or related field. 7+ yrs professional software engineering experience using modern object-oriented or functional languages (Python, Go, Scala, C++, TypeScript, etc). Proven experience delivering backend APIs, especially GraphQL, and consuming them from a modern web stack. Production experience with React, TypeScript, and modern CSS layout, with the judgment to build a usable interface for a complex workflow without a designer holding your hand. Experience building applications on cloud computing platforms such as AWS, Azure, GCP, using container technologies such as Docker and Kubernetes. Expert proficiency in SQL. Demonstrated experience designing and operating distributed systems in production: asynchronous workflows, queues, retries, idempotency, and partial failure. A track record of shipping and operating production services, including on-call ownership. What Sets You Apart Experience building agentic or LLM-backed systems in production Experience with a durable execution (such as Temporal) or workflow engine or having built equivalent checkpointing yourself. Experience building multi-tenant platforms with hard isolation requirements, workload identity, and short-lived credential brokering. Experience integrating a long tail of third-party APIs behind a normalized abstraction. Familiarity with security control planes and their APIs — EDR (CrowdStrike, SentinelOne, Microsoft Defender), firewalls, SIEM, cloud IAM. Experience with database architectures including relational (PostgreSQL) and graph (Neo4j), and experience building GraphQL backends. Experience with client-side data and streaming patterns — React Query or Apollo, GraphQL subscriptions, WebSockets — against long-running, incrementally updating state. Experience building operator-facing or admin interfaces where density, auditability, and getting the destructive action right matter more than visual polish. Experience with observability tooling (Datadog, Prometheus, Grafana) and distributed tracing. Awareness of prompt injection and untrusted-input handling in systems where an agent consumes data from the environment it operates in.

Lead development of scalable external reconnaissance and automated attack capabilities, research and validate techniques, set coverage priorities, and mentor engineers. | Requires 10+ years of hands-on offensive security or security-focused software engineering, including recent shipped offensive tools, strong Python, and expertise in reconnaissance, identity tradecraft, and attack automation. | Get to Know Us Horizon3 is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find and fix and verify exploitable attack vectors before criminals exploit them. Our flagship product, the NodeZeroTM platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises. It is used by ITOps/SecOps teams, consulting pentesters, and MSSPs and MSPs. We are a fusion of former U.S. Special Operations cyber operators, startup engineers, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools, false positives resulting in alert fatigue, blind spots, "checkbox” security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants. Collectively, we are a team of learn it alls, committed to a culture of respect, collaboration, ownership, and results. An Overview We're looking for a Staff Attack Engineer to be a technical leader for external attack capabilities in NodeZero, our autonomous pentesting platform. For most organizations, the external attack surface is where a breach begins. Customers need NodeZero to find the forgotten host, exposed credential, or misconfigured service, and prove how far each weakness leads. The surface is large and messy. It spans domains, certificates, cloud assets, code repositories, leaked data, identities, SaaS tenants, and the relationships connecting all of it. Much of it is unstructured, inconsistent, and hard to reason about in code. Attackers are also getting faster at finding and chaining these weaknesses together. This is a highly strategic role. You'll own large parts of the technical direction for our external attack domain: helping set the research and content roadmap, acting as a go-to subject matter expert, and raising the bar for the engineers building alongside you. This is not consulting or manual pentesting. The goal is to turn the manual recon and multi-step attack work that skilled operators do by hand into safe, reliable, repeatable workflows that run autonomously against some of the largest external attack surfaces in the world. What You’ll Do Design, build, and maintain highly scalable reconnaissance workflows that discover, enumerate, and fingerprint external-facing assets and services in production-grade Python. Research, explore, and parse large volumes of external-facing data, including unstructured and inconsistent sources, and turn it into accurate, actionable information. Develop robust approaches to data that is hard to reason about in code, such as free-form banners, web content, documents, and error output, and build parsing and enrichment that holds up across the long tail of real environments. Collect, store, and connect high volumes of information, and extend our attack-path modeling and graph data model to represent new identity, privilege, and relationship paths. Traverse identity relationships across the external surface, such as accounts, tenants, SSO and federation, exposed credentials, and third-party services, to find paths from exposure to compromise. Automate multi-step attack workflows that chain discovery, credential access, initial access, and post-exploitation into complete, safely proven attack paths. Research emerging external tradecraft and turn it into production attack content, with an emphasis on techniques that still succeed against hardened, well-monitored targets. Stand up and maintain representative test environments to validate, demonstrate, and regression-test attack scenarios. Build for production safety and scale: respect target and customer environments, rate limits, and scope while running across very large attack surfaces. Set priorities and the coverage roadmap based on real customer environments, threat intelligence, and emerging techniques. Mentor and level up attack engineers, and raise the bar on code quality, research rigor, and operational safety. Collaborate cross-functionally with engineers, product managers, and customer-facing teams, and author internal documentation and external research and blog posts. What You’ll Bring Deep, hands-on offensive experience against external attack surfaces, from reconnaissance through initial access and post-exploitation. 10+ years of hands-on experience in offensive security, security research, or security-focused software engineering, with recent work building and shipping offensive tooling. Demonstrated experience building reconnaissance and discovery systems that run at scale, not just one-off scripts. Strong skill at researching and parsing large amounts of messy, unstructured external data and turning it into usable, trustworthy information. Experience collecting, storing, and connecting high volumes of data, and reasoning about it as relationships, such as identities, assets, and trust. Command of identity-focused tradecraft: credential access, password and token attacks, SSO and federation weaknesses, and moving among identities, tenants, and services. Experience automating multi-step attack workflows end to end. Strong software engineering fundamentals with Python, and a track record of shipping and maintaining production-quality code, not just scripts and proofs of concept. Ability to independently research unfamiliar systems and technologies and rapidly become the team's expert. Strong written and verbal communication, including clear technical documentation. A passion for building products, not just finding vulnerabilities. What Sets You Apart OSCP (or OSEP, CRTO, or equivalent offensive certifications). Experience with large-scale internet data sources and tooling, such as certificate transparency, passive DNS, and internet-wide scanning. Experience with cloud, SaaS, and hybrid identity attack surfaces (Entra ID, Okta, AWS, and similar), including on-prem to cloud pivots. Experience with external to internal pivoting and how perimeter footholds lead into additional access. Experience with graph databases and attack-path analysis, and with datalake or high-volume data storage and processing. Experience developing or contributing to offensive or recon tooling Public contributions to the field: open-source tools, technical blog posts, conference talks, or published CVEs. Experience building production-safe autonomous or automated offensive tooling. Travel Required We are a fully remote company, and this job may require up to 5% of travel to be successful.

Own database platform architecture and standards, contribute hands-on code, mentor engineers, and guide the technical roadmap for scalability and data migration. | Requires 10+ years of experience, deep production PostgreSQL expertise, large-scale multi-tenant database architecture, Go or Python proficiency, and cross-team architectural leadership. | Get to Know Us Horizon3 is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find, fix and verify exploitable attack vectors before criminals exploit them. Our flagship product, the NodeZero™ platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises. It is used by IT Ops/SecOps teams, consulting pentesters, and MSSPs and MSPs. We are a fusion of former U.S. Special Operations cyber operators, startup engineers & operators, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools and false positives, resulting in alert fatigue, blind spots, "checkbox" security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants. Collectively, we are a team of learn-it-alls, committed to a culture of respect, collaboration, ownership, and results. What You'll Do The Principal Engineer for Database Platform is the technical anchor of NodeZero's data infrastructure. This is an individual contributor role with no direct reports — your influence is through technical leadership, architecture ownership, and raising the engineering bar across the team. You own the most consequential database architecture decisions, define the standards that govern how NodeZero stores, queries, and migrates data at scale, and ensure the data layer can support NodeZero's growth — more customers, larger environments, more pentest data — without requiring proportional operational effort. This is a deeply hands-on role: you will write code, author design documents, and set the technical direction that every engineer on the Database Platform team builds toward. NodeZero's data layer is not simple. We store millions of discovered assets, graph-structured attack paths, time-series vulnerability data, and audit-critical pentest results — across a multi-tenant architecture where correctness and data isolation are non-negotiable. You will be the person who makes the hardest data architecture calls and ensures the team has the technical foundations to build reliably on. Technical Strategy: Define and drive the technical roadmap for the Database Platform in partnership with the Senior Engineering Manager and the broader Pentest Platform organization. Architecture Leadership: Own the most complex database architecture decisions — schema design, partitioning strategies, migration patterns, and scalability approaches. Produce design documents that become the shared technical model for the team. PostgreSQL Excellence: Be NodeZero's definitive expert on PostgreSQL at scale — query optimization, indexing, partitioning, replication, and connection pooling. Set the standards the team follows and catch the problems others miss. Graph & Multi-model Data: Architect and guide the evolution of NodeZero's graph-based asset model — the data structure that represents how discovered hosts, services, credentials, and vulnerabilities relate to each other across pentests. Schema Governance: Own schema design review processes. Ensure every migration is safe, reversible, and zero-downtime. Build the tooling and culture that treats schema changes with the same rigor as production code changes. Mentorship & Bar Raising: Mentor P5 and P4 engineers through code review, design review, and pairing. Be the person on the team that raises everyone else's ceiling. Cross-functional Influence: Partner with Data Ingestion, Asset Inventory, API Platform, and Security Research to define data contracts, query performance standards, and architectural guardrails that span the full data pipeline. What You'll Bring Technical Depth Deep, production-proven PostgreSQL expertise: query planner internals, advanced indexing (partial, expression, GiST/GIN), partitioning strategies, logical replication, vacuuming at scale, and connection pool tuning. Experience architecting multi-tenant databases at scale: row-level security, tenant isolation, schema-per-tenant vs. shared-schema tradeoffs. Experience with schema migration at scale in production systems: zero-downtime migrations, backwards-compatible schema evolution, and migration tooling (Flyway, golang-migrate, or equivalent). Familiarity with graph data models and graph databases (Neo4j, AWS Neptune) or graph-like query patterns in relational systems (recursive CTEs, ltree, adjacency list). Proficient in Go or Python — able to write production application code, not just SQL. Architecture & Design Demonstrated track record of defining database architecture at scale — from design doc to production — across multiple companies or teams. Strong opinions on data architecture tradeoffs: normalization vs. denormalization, consistency vs. availability, OLTP vs. OLAP workload separation, and schema-first vs. schema-last design. Able to reason about long-horizon schema design: what does this schema look like in two years, at 10× the current data volume, with three new feature teams writing to it? Able to communicate complex database decisions clearly in writing — for design docs, ADRs, and cross-team reviews — so engineers without deep DB expertise can understand and apply the reasoning. Leadership Without Authority Proven ability to drive database standards across multiple teams without direct reporting authority — including teams that are not the Database Platform team. Experience establishing database engineering culture: schema review norms, migration safety standards, and query performance review processes. Track record of growing engineers through code review, pair programming, and architectural mentorship — especially engineers who are strong in application code but earlier in their database expertise. Nice to Haves Background in cybersecurity data: vulnerability databases, network scan schemas, or attack surface management data models. Experience with time-series databases (TimescaleDB, InfluxDB) in addition to relational. Familiarity with data platform compliance requirements: SOC 2 Type II, FedRAMP data handling, or GDPR/CCPA. Experience with analytical query patterns or BI/reporting workloads on operational data. Contributions to open-source database tooling or PostgreSQL ecosystem projects.

Own and execute ABM strategy to drive pipeline growth and accelerate deal velocity across multiple channels with sales alignment. | 6+ years B2B marketing in SaaS with proven ABM strategy experience and proficiency in ABM tech and Salesforce. | Get to Know Us Horizon3 is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find and fix and verify exploitable attack vectors before criminals exploit them. Our flagship product, the NodeZeroTM platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises. It is used by ITOps/SecOps teams, consulting pentesters, and MSSPs and MSPs. We are a fusion of former U.S. Special Operations cyber operators, startup engineers, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools, false positives resulting in alert fatigue, blind spots, "checkbox” security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants. Collectively, we are a team of learn it alls, committed to a culture of respect, collaboration, ownership, and results. What You’ll Do We are seeking a Staff ABM Manager to own Horizon3's account-based marketing strategy and execution across our highest-priority target accounts. This is a hands-on, high-impact role responsible for orchestrating personalized, multi-touch programs across digital, field, direct mail, and sales channels - designed to open doors with net-new prospect accounts, accelerate pipeline velocity, engage buying groups at in-flight opportunities, and deepen penetration within key accounts. You will report directly to the Director of Campaigns, ABM, and Marketing Operations and work in close partnership with sales, SDRs, field marketing, digital, and product marketing to ensure ABM is a coordinated motion - not a siloed program. Every account gets a plan. Every plan has a pipeline outcome. Every outcome gets measured. This is not a campaign execution role in the traditional sense. It's an account intelligence and orchestration role that uses marketing as a precision instrument to help sales win. ABM Strategy and Account Planning Own Horizon3's ABM strategy across all tiers - from one-to-one programs for highest-priority enterprise accounts to one-to-few and one-to-many plays for broader target account lists. Partner with sales leadership and SDR leadership to define and maintain the target account list, segmented by tier, segment, intent signal, and pipeline stage. Develop account-level program plans for tier-one accounts - including buying group mapping, engagement gap analysis, message personalization, and coordinated channel sequencing across digital, field, direct mail, and sales. Build and maintain a structured ABM planning and reporting cadence with sales - ensuring account plans are live, shared, and updated as accounts progress or stall. Program Execution and Orchestration Design and execute multi-touch ABM programs that meet buyers where they are - combining Influ2 contact-level advertising, ZoomInfo Co-Pilot intent targeting, Reachdesk direct mail and gifting, LinkedIn, field event invitations, and coordinated SDR outreach into cohesive account plays. Build tiered plays for different account scenarios: cold prospect accounts with no engagement, accounts showing intent but no active conversation, accounts with open pipeline that need acceleration, and velocity accounts approaching decision. Partner with field marketing to extend ABM plays into in-person experiences - CISO dinners, roundtables, bespoke Enterprise events/experiences, and executive events designed to engage specific buying group members at priority accounts. Coordinate with digital on paid media targeting, ensuring Influ2 and LinkedIn programs are running against the right contacts at the right accounts with the right message at each stage of the buying journey. Partner with product marketing to develop account-relevant proof points and personalized content - ensuring the right case study, benchmark, or use case is in front of the right persona at the right time. Direct Mail and Gifting Programs Own Horizon3's direct mail and gifting strategy as a precision ABM tool - not a spray-and-pray tactic. Build tiered gifting plays through Reachdesk or equivalent platforms, coordinated with SDR outreach and field invitations to maximize response rates and meeting conversion. Define and enforce clear thresholds for when gifting is deployed, to whom, and how follow-up is structured - ensuring spend is tied to meeting outcomes, not activity metrics. Sales and SDR Alignment Serve as the primary ABM partner to sales and SDR leadership - running account planning sessions, sharing intent and engagement signals in real time, and coordinating follow-up sequencing across all active ABM plays. Build visibility into account engagement for sales reps - ensuring they know when a target contact has engaged with an ad, opened a mailer, attended an event, or shown a surge in intent, and have a clear next action. Partner with SDR leadership to design SDR sequences that complement ABM touches rather than running parallel and disconnected. Hold a regular ABM performance review with sales and demand gen leadership - covering account engagement, pipeline influence, meeting conversion, and program ROI. Technology and Intelligence Own the ABM technology stack in partnership with marketing ops - including Influ2, Reachdesk, ZoomInfo Co-Pilot, and Salesforce campaign attribution. Use intent data, engagement signals, and account activity to continuously refine target account prioritization and program design - moving accounts between tiers as signals shift. Ensure all ABM activity is correctly attributed in Salesforce, with consistent UTM structure, campaign membership, and pipeline influence reporting. Measurement and Optimization Define and own ABM KPIs: account engagement rate, buying group coverage, meetings booked from ABM plays, pipeline influenced, pipeline generated, and stage progression velocity within ABM accounts vs. non-ABM accounts. Build and maintain a reporting framework that gives leadership clear visibility into what's working at the account level and the program level - and what isn't. Continuously test and optimize messaging, channel mix, sequencing, and offer to improve conversion at every stage of the ABM motion. What You’ll Bring 6+ years of B2B marketing experience, owning strategy and execution at a high-growth SaaS or technology company. Proven track record designing and running ABM programs that generate measurable pipeline and accelerate deal velocity - with the data to back it up. Hands-on experience with ABM and intent technology: 6Sense, Bombora, Influ2 or equivalent contact-level advertising platforms, Reachdesk or equivalent gifting platforms, and ZoomInfo. Strong command of Salesforce for campaign attribution, account-level pipeline tracking, and ABM reporting. Experience working in close partnership with sales and SDR teams - comfortable in account planning sessions, pipeline reviews, and direct collaboration with AEs and SDR managers. Ability to build buying group maps, account engagement plans, and tiered program plays from scratch - and execute them with precision. Strong cross-functional collaboration skills; ability to work effectively with field marketing, digital, product marketing, and marketing ops to orchestrate coordinated account plays. Highly organized with strong project management instincts - able to run multiple account plays simultaneously across different tiers, stages, and segments without losing detail or momentum. Comfort working with complex, technical subject matter and translating it into account-relevant messaging that resonates with security buyers including CISOs, security architects, and IT/SecOps practitioners. What Sets You Apart? Experience in cybersecurity, DevSecOps, or adjacent B2B security markets. Familiarity with LinkedIn Campaign Manager for account-targeted paid programs. Experience with direct mail and gifting programs as a coordinated ABM play, not a standalone tactic. Experience supporting Federal or Public Sector ABM motions. Familiarity with Pardot, Marketo, or HubSpot for campaign setup and marketing automation in support of ABM plays. Travel Required This is a remote role that may require up to 20% travel for key field events, internal offsites, and sales team alignment. Job-related travel expenses are reviewed and must be approved by your manager. Perks of Horizon3 Inclusive Team: We value diversity and promote an inclusive culture where everyone can thrive.
