Job Description
Senior Backend Engineer, Ruby/Go – Tenant Scale, Cells Infrastructure
GitLab
• Design and implement edge traffic routing that directs requests to the correct Cell in a way that's transparent to users. • Build and evolve the Topology Service that serves as the authoritative source of cluster state for routing, resource assignment, and Cell lifecycle decisions. • Collaborate across the GitLab Rails monolith and supporting services to make features and data models Cell-aware with feature teams across the product. • Operate and improve the routing and topology systems you build by participating in tier-2 on-call, responding to escalated incidents, and strengthening observability and operational tooling. • Author Architecture Decision Records (ADRs), operational runbooks, and documentation so other teams can understand, adopt, and extend the Cells platform. • Review merge requests from GitLab team members and community contributors, maintaining high standards for correctness, performance, and security across the stack.
Job Requirements
- 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).
