Senior Backend Engineer, Architecture Engineering: Nonlinear Productivity

What you'll do:

• Identify sources of friction across GitLab's software development lifecycle and scope agentic solutions to address them.
• Design and build reliable AI-powered systems that follow step-by-step workflows, use tools and safety checks, and correct errors before taking engineering action.
• Build and maintain evaluation tools that judge agent output on correctness, constraint compliance, and cost.

What you'll bring:

• Hands-on experience building agentic or large language model-based systems with multi-step orchestration, tool use, guardrails, and recovery patterns.
• A track record of working autonomously in unfamiliar codebases, getting oriented quickly, and driving solutions through completion.
• Strong distributed systems knowledge including coordination, consistency, idempotency, rate limiting, failure modes, and degradation under load.

About the team:

• Nonlinear Productivity is a strategic incubation group that reports into AI Platform leadership under the direct sponsorship of the CTO.
• It operates like a startup with no dedicated product manager or pre-set backlog, and solutions that prove out internally are the path to a monetized, customer-facing GitLab offering.
• The team is split into US and India groups that sync on roadmap and tooling a few times a week, otherwise running day to day on their own.
