Job description

Remote, EMEA

GitLab is an open‑core software company that develops the most comprehensive AI‑powered DevSecOps Platform, used by more than 100,000 organizations. Our mission is to enable everyone to contribute to and co‑create the software that powers our world. When everyone can contribute, consumers become contributors, significantly accelerating human progress. Our platform unites teams and organizations, breaking down barriers and redefining what’s possible in software development. Thanks to products such as Duo Enterprise and Duo Agent Platform, customers get AI benefits at every stage of the SDLC.

GitLab’s high‑performance culture is driven by its values and continuous knowledge exchange, allowing team members to reach their full potential while collaborating with industry leaders to solve complex problems. Co‑create the future with us as we build technology that transforms how the world develops software.

The Agent Foundations group focuses on developing the foundations of Agents and Flows, an AI system to automate tasks and increase productivity in the development workflow. As our new Staff Backend Engineer, you’ll build out our core service that hosts and coordinates our AI agents and enables teams both inside and outside GitLab to build their own agents. You’ll lead efforts to ensure the service follows up‑to‑date best practices for Python web development, orchestrate communication between services via gRPC, and contribute to core AI functionality in a company whose main language is Ruby.

• Write high‑quality, efficient, and maintainable code while adhering to best practices and contributing to code reviews
• Build a highly scalable web platform based on Python and gRPC that can be deployed in different environments
• Design and develop interactions with the latest LLMs
• Contribute to a testing infrastructure that allows us to verify agentic AI behaviours
• Embrace continuous learning and stay connected with industry best practices, tools, and technologies around AI to drive improvements in our software
• Provide technical mentorship and guidance to engineers across the Code Creation team and collaborate with other teams
• Influence product and engineering decisions by proposing thorough, iterative solutions to complex technical and architectural challenges
• Collaborate with cross‑functional teams across product, engineering, marketing, and more
• Represent the team in technical discussions with customers and stakeholders about AI‑powered development capabilities
• Participate in Tier 2 or Tier 3 weekday, weekend, and/or occasional night on‑call rotations to assist troubleshooting product operations, security operations, and urgent engineering issues

What You’ll Bring

• A deep interest in the way AI will change the process of software development
• Multiple years of experience building Python Web Services in a multi‑service environment (e.g. FastAPI, Starlette)
• Proven ability to architect and lead complex technical projects from concept to production across distributed systems
• Strong experience with AI/ML technologies, including integration with large language models and understanding of prompt engineering
• Deep expertise in performance optimization, particularly for systems handling high‑volume API requests
• Experience designing and building distributed systems with a focus on reliability, observability, and scalability
• Demonstrated ability to drive technical decisions and influence engineering strategy across multiple teams
• Experience mentoring engineers and raising the technical capabilities of a team
• Excellent written and verbal communication skills for collaborating in a remote, globally distributed environment
• Ability to work effectively across different technology stacks and quickly learn new languages and frameworks as needed
• Experience with the gRPC framework is a plus
• Experience with languages that our other services use such as Go, Typescript, Ruby or IDE Extension development is a plus

About the team

The Agent Foundations group is a team distributed across 3 continents but unified by the desire to shape the future of software engineering. We’re hard at work creating a product and the infrastructure that changes development processes, building the tools of tomorrow.

We’re partnering with teams both within the AI space as well as all over GitLab to ensure that Duo Agent Platform can become the backbone of many AI features at GitLab.

Please note that we welcome interest from candidates with varying levels of experience; many successful candidates do not meet every single requirement.
