Top Engineering Jobs in London

Build, test, ship, and operate production backend features using Ruby/Rails, Go, or other modern languages. Design APIs, background jobs, integrations, data models, migrations, and services while ensuring security, performance, reliability, and observability. Review code, investigate failures, reduce technical debt, provide operational support, collaborate asynchronously with product and engineering teams, and use AI coding tools responsibly.

Provides technical leadership across teams by designing and delivering large-scale backend initiatives, modernizing monolithic systems, defining architecture and engineering standards, and improving reliability, security, observability, and operability. The role establishes Go and Kubernetes patterns, guides Rust adoption, participates in incident response, mentors engineers, influences platform roadmaps, and leads safe adoption of AI-assisted and agentic engineering workflows.

Design, build, and maintain secure, tested, performant backend integrations connecting GitLab agents with tools such as Slack, Claude Code, and Codex. Own complex features, develop GraphQL and REST APIs, improve automated testing, troubleshoot production issues through on-call rotations, enhance observability and resiliency, and collaborate across product, frontend, backend, and AI engineering teams.

Lead cross-functional Developer Experience initiatives across six teams, contributing hands-on backend code in Ruby and Go. Improve testing reliability, test coverage, CI/CD pipelines, logging standards, and development environments. Partner with engineering, platform, product, and infrastructure teams to identify friction, remove systemic bottlenecks, shape the Developer Experience Platform strategy, and foster continuous engineering improvement.

As a Staff Backend Engineer at GitLab, you'll enhance backend infrastructure for CI, integrate AI features, and ensure reliability and performance in CI/CD workflows.

As a Forward Deployed Engineer, you will work on customer integrations with GitLab, designing and implementing solutions in complex enterprise environments while partnering with stakeholders to enhance adoption and reduce time to value.

Build and operate GitLab’s Gitaly backend storage systems, focusing on distributed storage, Git repository management, reliability, scalability, performance, and observability. Own complex technical initiatives end to end, lead system design, collaborate across engineering and customer-facing teams, mentor engineers, improve development practices, respond to incidents, participate in on-call duties, and implement operational improvements for production systems.

Lead GitLab’s Build team and roadmap, overseeing systems that convert source code into secure, verified, distributable artifacts. Own build platforms, dependency management, CI templates, supply-chain security, build consistency, observability, and self-service onboarding across delivery targets including Omnibus and CNG. Partner across teams to improve reliability, reduce coordination overhead, and support four-nines service objectives. Manage a distributed, high-performing engineering team and guide architecture, technical strategy, operational excellence, and complex project delivery.

Build tooling, workflows, and guidance to make GitLab easier to deploy, validate, and operate across cloud-native and self-managed environments. Evolve deployment guidance, improve production-like ephemeral environments, and maintain consistent deployment artifacts and environment contracts across development through production.

Design, implement, and evolve moderate-to-complex backend features, improve system quality, reliability, and performance, mentor engineers, participate in incident response, define backend standards, and integrate agentic AI into production engineering workflows.
