Much of your work will involve building flow components and agentic flows in the Flow Registry, the Python framework built on LangGraph within our Duo Workflow Service that powers agentic chat, and integrating them with the GitLab Rails monolith.You’ll own complex backend features from start to finish across both services. You’ll integrate large language models and orchestrate multi-agent flows so customers can work faster and more securely across the software development lifecycle. This work sits where GitLab’s core platform meets its AI strategy, and reliability, performance, and answer quality directly shape the customer experience.<h2>What you’ll do</h2><ul> <li>Design and build flow components and agentic flows in the Flow Registry using Python and LangGraph within the Duo Workflow Service. These reusable building blocks power agentic Duo Chat and, increasingly, other AI features across GitLab.</li> <li>Develop, ship, and maintain backend features for GitLab Duo Chat across the Python Duo Workflow Service and the GitLab Rails monolith in a secure, well-tested, and performant way.</li> <li>Integrate new generative AI models, providers, tools, and multi-agent orchestration patterns into Duo Chat to expand its capabilities and improve answer quality.</li> <li>Design, implement, and review GraphQL and Representational State Transfer (REST) application programming interfaces (APIs) and related monolith logic, including chat entry points, permissions, and foundational-flow registration. Keep contracts with frontend clients and host systems reliable and clear.</li> <li>Improve debugging, observability, and test coverage using pytest, RSpec, and related frameworks; track and improve latency, error rates, and test coverage so AI-powered chat workflows stay reliable at scale.</li> <li>Collaborate with Product, User Experience (UX), frontend, and AI specialists to refine requirements and deliver high-quality improvements through iteration.</li> <li>Document standards, patterns, and learnings with other engineers, raising the bar for safe AI integration and evidence-driven engineering.</li> <li>Participate in Tier 2 on-call rotations to troubleshoot production issues, contribute to root cause analysis, and strengthen resiliency.</li> </ul><h2>What you’ll bring</h2><ul> <li>Significant experience building and maintaining production Python backends, including APIs, data models, and asynchronous or long-running workloads.</li> <li>Practical experience designing and shipping AI-powered, agentic backend features, including large language model integration, tool or function calling, and multi-agent orchestration. You use sound judgment about large language model limitations and safe use in production.</li> <li>Working proficiency in Ruby on Rails, or a strong willingness to learn it. Duo Chat integrates deeply with the GitLab monolith for chat entry points, GraphQL, permissions, and flow registration, and most of GitLab’s codebase is written in Ruby.</li> <li>Proficiency designing or extending REST or GraphQL APIs with attention to scalability, maintainability, and backward compatibility.</li> <li>Strong Structured Query Language (SQL) skills and familiarity with relational databases such as PostgreSQL, including efficient queries and data modeling.</li> <li>Ability to find, diagnose, and prevent performance and reliability problems at scale.</li> <li>Experience solving technical problems of high scope and complexity and advocating for quality, security, and performance improvements across your team.</li> <li>Openness to learning and collaborating in an async-first, distributed team, applying transferable skills from related technologies or domains.

This part of the system needs to handle significant scale and stay highly available, since it's core to automated AI-enabled work across the platform.

What you'll do

Design and build the trigger system that links GitLab events, including code pushes, merge request and issue changes, CI/CD results, and deployments, and third-party events from tools like Jira, Jenkins, and Slack to the AI-powered Duo Flows that act on them.
Contribute to the broader event platform, the core infrastructure that many of GitLab's AI features rely on to know when and how to run.
Architect for high availability and throughput, since this part of the system sits at the center of automated AI workflows across GitLab and needs to reliably process events at scale.
Work within GitLab's Rails monolith, where much of the event and trigger system lives, while staying open to other languages used elsewhere in the platform.
Influence product and architecture direction by proposing iterative solutions to complex technical problems across a multi-service environment.
Collaborate closely with your teammates, product manager, and designer to shape what the trigger system supports next, likely starting with an additional trigger type.
Partner cross-departmentally with other Duo Agent Platform teams to make sure triggers and events integrate cleanly with the broader agent ecosystem GitLab is building.
Participate in Tier 2 and Tier 3 on-call rotations to troubleshoot production, security, and urgent engineering issues in a globally distributed environment.

What you'll bring

Deep experience with Ruby and Rails, comfortable working within a large, established monolith and shipping production code effectively.
Proven track record building products that interact with large language models, not training or building machine learning models yourself, but with hands-on experience integrating large language models into real, user-facing tools.
Proven track record designing and operating systems built for large scale, with a focus on high availability and throughput in production environments.
Hands-on experience with agentic systems and development, including building workflows that let AI agents take autonomous action.
Demonstrated ability to make progress in evolving problem spaces and learn new AI capabilities quickly as the underlying technology shifts fast and this team ships while it learns.
Strong written communication skills for working asynchronously in a remote, globally distributed team.
Additional helpful experience includes Python, since other parts of GitLab's AI platform are built in it, and using GitLab as a product.
