About This Role

Join GitLab's Knowledge Graph team as an Intermediate Backend Engineer and help build a graph data service that powers GitLab Duo agents, analytics, and architecture-level features across GitLab.com, Dedicated, and Self-Managed deployments. You'll work within a small, Rust-focused team that prioritizes clear ownership, thoughtful system design, and rigorous thinking about data reliability and operational excellence.

What You'll Work With

The Knowledge Graph service is a Rust backend that constructs a property graph from GitLab's software development lifecycle (SDLC) and code data. The architecture leverages ClickHouse for analytics, NATS JetStream for messaging, and the Data Insights Platform for comprehensive insights. You'll build secure graph queries and Model Context Protocol (MCP) tools used by AI agents and product features across multiple deployment models.

Key Responsibilities

Implement and iterate on backend features in the Rust-based Knowledge Graph service, including query engine enhancements, SDLC and code indexing flows, and API endpoints (including MCP endpoints) under guidance from senior and staff engineers
Maintain and improve existing systems, reducing single points of failure through better test coverage and comprehensive runbooks
Contribute to observability, monitoring, and operational readiness initiatives that make the service easier to maintain and evolve
Take clear ownership of specific components or features during your first year, such as SDLC indexing pipeline segments or query paths
Help the team ship analytical services with improved maintainability and long-term sustainability
Participate in on-call rotations and incident response as part of operational responsibilities
