Senior Backend Engineer, AI Engineering: AI Coding

GitLab is the intelligent orchestration platform for DevSecOps, enabling organizations to increase developer productivity, improve operational efficiency, reduce security and compliance risk, and accelerate digital transformation.

As a Senior Backend Engineer, you'll join the AI Events team, which builds the event platform and trigger system that power GitLab Duo Flows. You'll design and build the trigger system that links GitLab events and third-party events to AI-powered Duo Flows.

Responsibilities:

• 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.
• 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.

Requirements:

• 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.

Benefits:

• Benefits to support your health, finances, and well-being
• Flexible Paid Time Off
• Team Member Resource Groups
• Equity Compensation & Employee Stock Purchase Plan
• Growth and Development Fund
• Parental Leave
