As a Backend Engineer on the Chat Engine team, you'll build the engine behind GitLab Duo
Chat, the conversational AI experience for GitLab. You'll work primarily in Python to build
and maintain our agentic runtime: the Flow Registry, LangGraph flows, and the Duo Workflow
Service. You'll also work in the GitLab Rails monolith, where Chat connects with the
product.
You'll own scoped parts of the system, ship small features and improvements with minimal
guidance, and collaborate with the team on larger projects. You'll work alongside senior
and staff engineers who will partner with you on design and support your growth.
What you’ll do

Develop secure, well-tested, and performant features and improvements for GitLab Duo Chat.
Implement and extend agentic flows in Python using LangGraph, registered through the Flow
Registry and served by the Duo Workflow Service.
Integrate Chat capabilities with the GitLab Rails monolith, including its GraphQL application
programming interface (API).
Write maintainable code that meets our internal standards for a high-scale environment,
including tests with every merge request.
Review code within our Code Review Guidelines and respond promptly to contributions from people
who don't work for GitLab.
Identify technical debt and propose and implement solutions that improve the team's
efficiency.
Collaborate with Product Management, User Experience, and Frontend team members to improve
product quality, security, and performance.
Participate in Tier 2 or Tier 3 weekday, weekend, and occasional night on-call rotations to
help troubleshoot product operations, security operations, and urgent engineering issues.

What you’ll bring

Professional experience with Python, including building and testing production services.
Working proficiency with Ruby on Rails, or a willingness to learn it, since a meaningful part
of Chat lives in the GitLab monolith.
Exposure to, or strong interest in, building on top of large language models, including
prompting, tool or function calling, evaluation, and the failure modes of non-deterministic
systems.
Experience designing and building APIs, including diagnosing and optimizing performance issues,
and comfort working with well-documented third-party services.
A security-minded development approach that applies secure coding guidelines early in the
development process.
Clear and concise written communication about technical problems and iterative solutions, which
is essential in a remote, largely asynchronous environment.
Manage work independently, organize priorities, and ask for help when an issue is taking longer
than expected.
Demonstrate GitLab's values by collaborating effectively in a fully remote, intensely
iterative environment.
Experience with LangGraph, LangChain, or a comparable agent orchestration framework.
Experience with GraphQL and RSpec.
Experience with the GitLab product as a user or contributor.
Experience working on a remote, globally distributed team.

About the team
We're part of GitLab's AI Engineering organization and own the AI-powered chat
experience embedded across the GitLab platform. Chat Engine is the backend-focused team within
the Duo Chat group. We're backend, frontend, and AI specialists working asynchronously
across time zones, using issues, merge requests, and documentation as our main collaboration
tools. We focus on expanding generative and agentic AI capabilities, improving the performance
and reliability of chat workflows, and strengthening the debugging and testing foundations that
help us run AI features safely at scale.
