What you'll do
- Own the technical thesis for how GitLab validates software when an agent is the author, and turn it into an architecture the team can build against.
- Prototype the hard parts by building early versions of feedback mechanisms that catch the gap between passing tests and working software, proving what works before the team scales it.
- Develop approaches for GitLab's primary stacks, starting with Rust, Ruby, and Go, under one shared definition of "trusted," while allowing the right technique to differ by language.
- Design the mid-loop feedback an agent needs to self-correct toward working software rather than green assertions, and build the systems that deliver it.
- Collaborate with engineering teams to adopt these approaches, measure adoption, engineer trust, and validation quality, and use those findings to improve the platform.
- Set technical direction the team can build on, review designs, and help teammates grow their technical judgment.
- Take part in on-call or operational support where your team's ownership model requires it.
What we're looking for
- Deep, current, hands-on experience building real software with artificial intelligence agents, ideally across more than one language, and a clear understanding of why agent output can pass tests yet fail in production.
- A strong point of view on the validation gap and concrete ideas for closing it, backed by approaches you've built or tried.
- Experience designing distributed systems designed to run on Kubernetes first.
- The technical range to design systems rather than tune a single framework, and the judgment to know when a solution should be general or language-specific.
- You prototype to learn, and you ship.
- The ability to influence engineers across an organization without formal authority through working code and sound reasoning.
- Strong written communication in an all-remote, asynchronous environment.
- Alignment with GitLab's values, especially collaboration, iteration, and transparency.
