Senior Backend Engineer, Trusted Agentic Development

Job summary

Responsibilities

The Trusted Agentic Development team sits within GitLab's Developer Experience group and builds the platforms our engineers rely on every day. GitLab engineers increasingly build software with artificial intelligence agents.

• Validation that confirms agent-generated code does what was intended, so a passing suite means a working feature and not just a satisfied proxy.
• Mid-loop feedback that helps an agent self-correct toward working software instead of green assertions.
• Language-aware approaches under one shared model of what "trusted" means, starting with Rust, Ruby, and Go, while allowing the right technique to differ by language.
• Real measurement of whether engineers trust and adopt the path, fed straight back into the platform.
• 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.

What they'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…
• 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.
