Senior Backend Engineer, Trusted Agentic Development

About the Company

Responsibilities

• ● 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.

Requirements

• ● 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.
• ● 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.
• ● This isn't a quality assurance or test automation role. We aren't looking for depth in a particular testing framework. We're looking for someone who has built with agents, experienced the validation gap firsthand, and wants to solve it.
• ● About the team
• ● The Trusted Agentic Development team is part of GitLab's Developer Experience group. We build platforms and practices that help GitLab engineers validate agent-generated software with confidence. We work across engineering teams and programming languages to understand how people use agents, test new approaches in real workflows, and create a shared model of trusted agentic development that teams choose to adopt.
