Senior Backend Engineer (Ruby), AI Engineering: AI Coding

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.

Additional helpful experience includes Python, since other parts of GitLab's AI platform are built in it, and using GitLab as a product.

We're part of GitLab's AI Engineering organization. We're a small team with members based in Europe, and we're growing. We work closely with our manager, product manager, and designer, and we coordinate cross-departmentally with other AI Engineering teams, since GitLab's AI teams work closely together.

We operate async-first, communicating through GitLab issues and Slack, with async standups and regular one-on-ones. We value autonomy and ownership, giving engineers the authority to make decisions and move quickly, balanced with high context sharing across the group. AI is a top priority at GitLab, and we work on cutting-edge technology in a high-impact, high-visibility part of the company.
