Design, implement, and maintain high-quality backend scanning engine services with a focus on performance, scalability, and security.
Senior backend engineer with strong Python or Go skills, systems design experience, and ability to work in cloud-native environments on scanning or similar high-throughput systems.
Responsibilities • Own end-to-end systems design for key components of the scanning engine, from initial design through implementation, deployment, and ongoing iteration • Design and implement high-quality services in Python and Go that power our scanning workflows, ensuring code is maintainable, well-tested, and observable. • Improve performance, scalability, and reliability of the scanning engine, optimizing for large-scale, distributed scanning workloads and strict SLAs. • Partner with security, product, and data teams to translate detection and scanning requirements into robust, production-ready systems and APIs. • Drive technical excellence and standards in the scanning engine codebase, including code review rigor, design documentation, and best practices for secure coding. • Contribute to architecture and roadmap decisions for the scanning platform, evaluating tradeoffs and proposing solutions that balance speed, quality, and risk. • Diagnose and resolve complex production issues related to scanning performance, accuracy, and stability, collaborating with SRE/Infra teams where needed. • Mentor and support other engineers on the team through design feedback, pairing, and knowledge sharing around systems design and scanning domain concepts. Skills and Qualifications • Strong experience as a Senior Software Engineer (or equivalent) working on backend or systems-level services. • Proficiency in at least one of Python or Go, with the ability and willingness to work in both languages over time. • Demonstrated experience with systems design for distributed or high-availability services, including clear understanding of scalability, reliability, and observability. • Hands-on experience building or maintaining scanning, detection, or similar engine-like systems (e.g., vulnerability scanning, security scanning, data processing pipelines, or similar high-throughput engines). • Clarify how strict security/scanning background is vs. openness to adjacent domains (data pipelines, compilers, search, etc.). • Strong software engineering fundamentals: data structures, algorithms, concurrency, and performance optimization. • Experience working in a cloud-native environment (e.g., microservices, containers, CI/CD, monitoring, logging). • Confirm primary cloud provider(s) and any required tools (Kubernetes, Docker, etc.). • Ability to collaborate effectively across teams, including product, security, and platform/infra, and communicate tradeoffs clearly to technical and non-technical stakeholders. • Proven track record of owning projects end-to-end, from problem definition and design through implementation, rollout, and iteration. • Comfort operating in a fast-paced, evolving environment, making pragmatic technical decisions while maintaining quality and security. • Experience with code quality practices (testing, static analysis, code reviews) and building maintainable systems. Bonus Points • Cyber security domain knowledge in scanning through endpoints. Compensation Our compensation reflects the cost of labor across several US geographic markets.
