  • ● Set technical direction for GitLab Dedicated, shaping architecture and platform strategy as we scale a growing fleet of isolated, single-tenant environments.
  • ● Lead platform transformations across resilience, failover, tenant orchestration, change management, self-service tooling, and platform integrations.
  • ● Drive scalable, modular architecture that aligns Dedicated with GitLab's broader Cells strategy while preserving its security, isolation, and compliance requirements.
  • ● Strengthen service ownership and operational maturity, helping engineering teams build, operate, and improve the production systems they own.
  • ● Identify and address systemic reliability and scalability risks using production signals, incident patterns, and architectural insight.
  • ● Establish reusable platform patterns and automation that reduce operational toil and allow Dedicated to scale efficiently.
  • ● Lead complex technical decisions across teams, balancing reliability, security, cost, maintainability, and customer needs.
  • ● Advance engineering excellence across the organization through architectural leadership, mentorship, and influence with senior engineers and engineering leaders.
  • ● What you will bring
  • ● Deep expertise in Site Reliability, Platform, Infrastructure, or Backend Engineering, with experience designing and operating large-scale production systems.
  • ● Hands-on experience with cloud infrastructure, automation, observability, infrastructure as code, and modern production engineering practices.
  • ● Strong software engineering fundamentals, with experience building production systems or infrastructure tooling in languages such as Go, Ruby, Python, or similar.
  • ● Strong distributed systems and systems-design expertise, with sound judgment around reliability, failure isolation, scalability, and operational complexity.
  • ● A track record of technical leadership across multiple teams, setting direction and driving complex initiatives through influence.
