Vannevar

You would lead technical strategy and engineering delivery for national-security accounts, guiding teams and systems from mission discovery through secure deployment and ongoing operations. | The role requires 5+ years of hands-on full-stack engineering, experience scaling software to enterprise use, an active Top Secret clearance with SCI eligibility, and experience in regulated government environments. | Vannevar builds AI systems for the Department of War's most consequential missions. We have 125 deployments across every branch and combatant command spanning our core platform and five distinct products. An an example of how we work, when major combat operations started with Iran, we fielded a new product supporting 24/7 operations and 9,000+ users in three months. How we build is our advantage: we deploy forward with the people who own the mission. Our engineers, product team, and CTO deploy forward to the point of friction, including visiting units in Ukraine. We focus on embedding directly with operational units supporting great power competition with China, combat operations with Iran, and counter-narcotics missions. About the role Vannevar is entering its next stage: scaling from early mission wins into an AI-native, non-traditional defense technology prime. Getting there means more than growing headcount — it means building new operating systems for how our people work, establishing processes that repeat reliably across accounts, and rethinking engineering delivery from first principles for this next phase of growth. Vannevar’s Mission teams work directly with national security customers, pairing small-team focus with a shared technology platform. As an Enterprise Technical Lead, you’ll own technical direction and engineering delivery for a portfolio of accounts (representing $10M–$50M in contract value) — organized around a service branch, combatant command, or emerging new mission area. You’ll guide work across the full customer lifecycle: discovering mission needs, shaping opportunities, testing concepts, and scaling capabilities into sustained operations. Using Vannevar’s Agent Control Plane — shared infrastructure for deploying AI solutions in national security environments — you and your team will prototype and test capabilities in areas like digital sensing, logistics, supply chain security, and defense health, then assess what’s ready to scale or transition to dedicated product teams. You’ll start as a hands-on technical leader on new accounts, learning the stack through direct engineering work — making architecture decisions, contributing to implementation, and coaching engineers. As your portfolio grows, you’ll build and lead the team behind it, while staying accountable for architecture and delivery. What you’ll do Technical leadership & delivery Set technical strategy across your portfolio, turning mission priorities into architectures, plans, and deployed capabilities Decide when to configure existing platform tools, build reusable extensions, or write mission-specific software — and push back on commitments that aren’t securely or sustainably deliverable Manage engineering capacity and priorities across accounts — so commitments never outrun the people available to deliver them Customer & opportunity work Work directly with customers and end users to understand mission needs and constraints — so what you build matches how the mission actually operates, not just how it looks from a requirements document Master each customer’s network topology, enterprise architecture, and mission applications — so you extend what already works instead of building a parallel silo, and design solutions that can mature into a Program of Record Shape new opportunities with customer success, BD, legal, and contracting — contributing technical content to ROMs and SOWs Build and validate prototypes with customers and product teams; guide what’s working toward production, scale, and eventual transition to dedicated product teams Platform contribution Feed recurring engineering challenges and reusable patterns into quarterly Platform/Product planning — so the platform evolves from what’s actually breaking in the field, not top-down roadmap guesses Enable FDEs to build improvements directly into the platform from the field — so fixes ship at the speed problems are found, instead of waiting on a centralized release cycle Execution & governance Produce architecture artifacts (system context, component, interface, data-flow, deployment diagrams — UML/SysML where useful) and track work in tools like Jira and Notion — so decisions are traceable and a team can pick up the work without you in the room Guide teams through security, compliance, and authorization requirements, coordinating with customer security stakeholders — so systems clear ATO and deploy on schedule instead of stalling in review People Mentor engineers and technical leads; as the role grows, take on performance feedback, reviews, and development planning — so the team can take on more of the portfolio without you as the bottleneck Travel Up to 20%, for customer discovery and delivery support Locations This role requires regular in-person engagement with customers and engineers; location will align with the portfolio you lead.

About the role Vannevar builds an agentic system that helps operators make sense of high-volume mission data and act with greater speed and confidence in sensitive government environments. The system analyzes millions of mission-relevant records to surface high-fidelity recommendations, near-real-time analysis, and decision-ready outputs while integrating into the systems and workflows customers already use. Our software is designed to augment, not replace, human judgment. Operators remain in control of consequential decisions, with the system helping them understand evidence, investigate recommendations, and move faster with better information. In this role, you will help expand the product to new missions, datasets, and operating environments. You will work directly with users and technical stakeholders to understand the mission, decide what should be built, and then build and deploy it. The team moves quickly — the first version of this system was deployed to in nine days — while holding a high bar for reliability, security, and usefulness to the people doing the mission. This is a senior individual contributor role with broad ownership. You will write code, make architectural and product decisions, navigate complex government technical environments, and own outcomes from an initial mission need through production deployment and continued use.
