The DAP Repository Flows team owns two areas within GitLab's Duo Agent Platform (DAP). The first is DAP onboarding, helping customers quickly set up a project so they can start using the Duo Agent Platform with minimal friction. The second is repository and background flows: autonomous and scheduled agents that work on a customer's codebase on their behalf.

This work is central to how GitLab delivers AI-powered automation on repositories. As a Senior Software Engineer, you will own features end to end, from design through delivery, building agentic experiences on top of the Duo Agent Platform.

• Own the design and delivery of features end to end across DAP onboarding and repository/background flows.
• Build autonomous and scheduled agents that operate on customer codebases, building on top of the Duo Agent Platform.
• Improve the DAP onboarding experience so customers can get a project configured and productive quickly.
• Collaborate with engineers across the DAP organization on shared interfaces and patterns.
• Review designs and code, and contribute to the team's technical quality.
• Contribute to a culture of autonomy, ownership, high context sharing, and async-first collaboration.

• Strong, hands-on experience with Ruby and Ruby on Rails in production systems.
• Experience integrating LLMs into products (product integration, not ML model training).
• Experience building agentic systems: autonomous or semi-autonomous agents that take actions on a user's behalf.
• A track record of designing and shipping features independently in a collaborative team.
• Strong written communication and the ability to operate effectively in a distributed, async-first environment.

The DAP Repository Flows team is part of GitLab's broader Duo Agent Platform organization, within the AI/R&D group. The team is small and distributed, with plans to grow. We value autonomy, ownership, and high context sharing, and we work async-first through GitLab issues and Slack.
