Work across GitLab’s codebase to scope and build agentic, LLM-driven systems that automate multi-step engineering workflows (e.g., code review and release steps). Require hands-on experience making agentic/LLM systems reliable in production, strong distributed systems knowledge, and proficiency in Go, Rust, or Python.

Join GitLab's Platform Readiness team to design and implement backend systems and agentic workflows (DAP) that evaluate platform readiness across Self-Managed, Dedicated, Dedicated for Government, and GitLab.com. Role requires 5+ years software engineering experience (2+ years backend/platform tooling) and strong proficiency in TypeScript/Node, Python, or Golang; responsibilities include schema design, CI integration, LLM/API integration, observability, and mentoring other engineers.

Work on the Duo Chat backend to design and build Flow Registry components using Python and LangGraph, integrate generative AI models and multi-agent orchestration, and implement GraphQL/REST APIs and monolith logic. Responsibilities include improving observability, test coverage (pytest, RSpec), performance and reliability, collaborating with product and UX, and participating in Tier 2 on-call rotations.

Work on tooling, workflows, and platform contracts to make GitLab easier to deploy, validate, and operate across self-managed and cloud environments. Responsibilities include contributing to cloud-native deployment guidance (component requirements, topology, scaling), improving ephemeral environments for earlier validation, and collaborating across application, infrastructure, and platform teams on packaging, testing, and delivery workflows.

Work on the Duo Agent Platform in the GitLab monolith (primarily Ruby) and occasionally the AI Gateway (Python). Responsibilities include designing and implementing GraphQL/REST APIs, developing backend features, improving automated tests (RSpec), troubleshooting production issues (Tier 2 on-call), and collaborating with product, UX, frontend and AI teams to ship scalable, secure AI-enabled backend functionality.

Work as a Senior Backend Engineer on GitLab's Authentication team to design and implement authentication and identity services (token issuance/validation, passkeys, SSO, OIDC, SAML, LDAP, SCIM) across the Rails monolith and the new GATE service. Role requires Go and/or Ruby experience, security and IAM knowledge, and remote work from the United States or Canada. US salary range provided.

Lead and contribute hands-on to developer tooling and an internal developer platform, working across teams to improve CI/test environments, Kubernetes onboarding, reliability, observability, and deployment workflows. Requires strong Go experience, familiarity with Ruby, practical Kubernetes and Helm knowledge, and demonstrated ability to provide technical leadership across engineering, infrastructure, and security teams.

Lead a backend engineering team within GitLab's Software Supply Chain Security (SSCS) Add-On to deliver enterprise-grade supply chain security features. Responsibilities include driving delivery and GA milestones, hiring and developing engineers, coordinating roadmap and cross-team dependencies, and advancing engineering quality; requires 3+ years managing backend/product engineering teams and relevant technical familiarity (package registries, CI/CD security, signing infrastructure, SLSA/Sigstore).
