About the role
As an Intermediate Backend Engineer in GitLab's Agent Foundations stage, you will help build the core platforms that power GitLab's agentic AI experiences across the entire software delivery lifecycle. Most of your work will center on backend engineering in Python using libraries like LangGraph and LangChain to implement secure, reliable, and performant features in the AI Gateway and Duo Workflow Service.

- Join Tier 2 on-call rotations to troubleshoot production issues and improve observability and resiliency.
What you bring
- Experience building and maintaining production Python backend applications, including APIs and async processing.
- Experience with LLM application frameworks such as LangGraph or shipping AI-powered backend features.
- Skill in designing scalable and backward-compatible APIs (REST, GraphQL, or gRPC).
- Clear written and verbal communication skills for technical proposals and documentation in an async team.
- Comfort working across the stack in a mature codebase, with Ruby on Rails or Vue experience being a plus.
