• Experience building observable, resilient production services using Go or Ruby on Rails (TypeScript experience is a plus). • Background delivering and operating production systems in high-scale environments, including incident response and operational ownership. • Ability to reason about distributed systems, including consistency models, partitioning strategies, failure modes, and operational tradeoffs. • Experience building high-throughput networking services (gRPC and protocol buffers knowledge is a plus). • Familiarity working in large, multi-team codebases and coordinating changes across teams and services, including making features and data models Cell-aware. • Knowledge of observability practices such as metrics, tracing, and alerting, with an approach focused on building systems you'd be confident operating on-call. • Strong written communication skills for an async-first, globally distributed team, including documenting decisions (for example, architecture decision records) and runbooks. • Experience working with relational databases in production, including schema design, migrations, and query performance tuning (PostgreSQL experience is a plus). • We're the Cells Infrastructure team within the Tenant Scale group in Infrastructure Platforms. We're a globally distributed, all-remote group of Backend Engineers and Site Reliability Engineers working asynchronously across multiple time zones. We own foundational services for GitLab's Cells architecture, including edge routing that directs requests to the right Cell and our topology systems that act as the source of truth for cluster state. Our challenge is making GitLab.com scale horizontally in a way that's reliable, low-latency, and operable, so every request reaches the right cluster and we can keep growing safely.
