Beacon Biosignals seeks a Staff Backend Engineer (Python) for the Duo Chat team within AI Engineering. You will lead the backend architecture powering GitLab Duo Chat across the DevSecOps platform, solving hard problems to build reliable, secure, and scalable AI-powered chat workflows that help customers plan, write, review, and secure code faster.
What You'll Do
- Define the technical architecture and technical roadmap for the Duo Chat group, aligning backend execution with product direction and engineering priorities.
- Solve the highest-scope and most ambiguous backend problems, delivering secure, well-tested, performant solutions with minimal guidance.
- Integrate and extend generative AI capabilities in GitLab Duo Chat, including large language models (LLMs) and providers such as Google Vertex AI.
- Develop, ship, and maintain backend features across Python and Ruby on Rails services that power Duo Chat experiences across the GitLab platform.
- Design, implement, and review GraphQL API contracts and supporting backend logic to ensure reliability, scalability, and clear frontend integrations.
- Improve observability, debugging workflows, and incident readiness by strengthening logging, tracing, and production troubleshooting practices.
- Drive code quality and long-term maintainability by setting internal standards, leading code reviews, and identifying and reducing technical debt.
- Mentor engineers across the team and participate in Tier 2 on-call rotations, contributing to root cause analysis and follow-up improvements to resiliency and testing.
What We're Looking For
- Production experience building and operating backend services in Python, including background jobs, APIs, and data models.
- Ability to define and evolve technical architecture by weighing trade-offs, selecting patterns and tools, and setting a clear technical direction for others to follow.
- Experience setting and driving a technical roadmap in partnership with product and engineering stakeholders.
- Proficiency designing and maintaining REST and/or GraphQL APIs with attention to scalability, maintainability, and backward compatibility.
- Hands-on experience integrating large language models into applications, including prompt design and building features powered by generative AI.
- Strong SQL skills and experience working with relational databases such as PostgreSQL, including efficient queries and data modeling.
- Experience mentoring engineers through code review, architectural guidance, and shared standards, and communicating complex technical decisions in a clear, async-first way.
- Comfort contributing in a mature codebase across Python and Ruby on Rails, with openness to learning and applying transferable skills from related technologies or domains.
