The Staff FDE will work directly with strategic customers, Product, Engineering, Support, SRE, SA, CSA, CSM, and Professional Services to diagnose and resolve high-impact adoption blockers, contribute production-grade fixes and features, and convert learning into repeatable patterns for GitLab and its customers. They are equally comfortable reading traces, writing production code, debugging architecture, discussing AI governance, leading a customer technical session, opening a merge request, writing a whitepaper outline, and coordinating across internal teams to achieve a strategic customer outcome.
