About the role
We are looking for a Principal Engineer to help build GitLab Duo Agent Platform, the agentic orchestration layer that runs AI agents and flows across the entire software lifecycle.
Principal Engineers at GitLab are recognized experts across multiple technology domains and represent the senior technical leadership within their organization. In this role you will set technical direction for a significant part of the Agent Platform, working across several teams to turn agentic capabilities into something engineering organizations can actually depend on: predictable, observable, governable, and fast enough to sit in the critical path of real development work.
The Agent Platform is not a single service. It spans agent execution and orchestration, flow definition and event-driven triggering, the AI Catalog through which customers discover and manage agents, model routing and evaluation, and the governance surface that decides which agents may act where and under whose identity. It runs on GitLab.com, GitLab Dedicated, and Self-Managed installations, including deployments that use self-hosted models to meet compliance requirements. You will work on the parts of that system where the hard architectural questions live, and you will do it hands-on.
This role reports into the VP of the AI Engineering organization and works closely with Engineering Managers, Staff Engineers, Product Management, Infrastructure and Security.
What you'll do
- Define the technical direction for a significant area of Duo Agent Platform across several teams, and partner with Engineering Managers and Product to turn it into a roadmap with a six-month horizon.
- Build the orchestration layer that makes agents and flows reliable: session lifecycle, tool invocation, context assembly, concurrency, retries, timeouts, and failure modes that degrade gracefully instead of stalling a developer's workflow.
- Hands on work on driving topics throughout the whole organisation from POC level, architecture to full implementation.
- Participate in Incident Management on-call rotation, to help meet availability goals for GitLab.com.
- Strong product builder and ownership mentality. Understanding of product strategy, technical strategy, delivering customer value and iteration towards a successful product
- Write clear, opinionated design documents, architecture narratives, and decision records that let other teams make aligned decisions. Ensure the architecture holds across multi-tenant GitLab.com, Dedicated, and Self-Managed deployments, including self-hosted model configurations, and respects data governance boundaries in each.
- Use the platform on our own work, find where it falls short of what we claim, and feed that back through improvements into the product.
- Mentor Staff and Senior Engineers, and raise the bar for experimentation rigor and cross-team collaboration.
- Work across the whole platform on different projects, features and teams. This reaches across:
- Complete Interview Training and participate in hiring for the department as a technical interviewer or panel member.
What you'll bring
- 8+ years of software engineering experience, including 3+ years at Staff, Principal level or equivalent senior technical leadership.
- Hands-on production experience building on large language models: agent loops, tool calling, context management, retrieval, prompt and model evaluation. Experience shipping this to real users, not only prototyping it.
- Strong background in distributed systems, including service decomposition, fault tolerance, observability, and operational resilience under multi-tenant load.
- A track record of defining evaluation frameworks and using benchmark and experiment results to make architecture decisions, rather than shipping on intuition.
- Experience designing human-in-the-loop controls, safety guardrails, and responsible AI practices for systems that act on a customer's behalf.
- Ability to drive alignment across Engineering, Product, Infrastructure, and Security on problems that start out ambiguous.
- Experience mentoring senior engineers and shaping technical direction across multiple teams without direct authority.
- Comfort working in one or more of Ruby, Go, Python, or TypeScript, and willingness to work across the stack the platform spans.
- Excellent written and asynchronous communication, and the ability to work effectively in a fully remote, globally distributed organization.
