Site Reliability Engineer, Infrastructure Platforms — UK (Intermediate to Senior Staff)

Overview

Site Reliability Engineers keep GitLab's user-facing services and production systems running reliably at scale. They combine software engineering with operational excellence, applying sound engineering principles, automation, and continuous improvement to build, operate, and evolve our production infrastructure.

This is a single application for Site Reliability Engineering opportunities across Infrastructure Platforms. We hire Site Reliability Engineers from Intermediate through Senior Staff across multiple Infrastructure Platforms teams.

*Please note: This position is open to candidates based in the United Kingdom only.*

What you'll do

• Keep user-facing services and production systems reliable, scalable, and efficient
• Build automation and tooling that reduces toil and replaces manual work with repeatable, infrastructure-as-code-driven workflows
• Operate and troubleshoot production systems on Kubernetes, including deployments, rollouts, and scaling
• Write and maintain infrastructure as code, and ship changes safely through CI/CD and GitOps
• Participate in on-call, triage alerts, follow and improve runbooks, and escalate appropriately
• Contribute to the observability stack, using metrics, logs, and SLOs to detect symptoms early rather than just outages
• Take part in incident response and post-incident reviews, turning learnings into changes in automation and process
• Document runbooks, architecture decisions, and reviews so your findings become repeatable practices

What you'll bring

• Experience keeping production systems reliable, combining an operations mindset with real software engineering practice
• Experience building net-new infrastructure tooling and automation (e.g., Terraform modules, Kubernetes operators/controllers, or custom automation/services)
• The ability to read, debug, and reason about code (most teams work in Go; some work in Ruby)
• Experience with infrastructure as code, and with Kubernetes and its ecosystem
• Hands-on experience with at least one major cloud provider (GCP or AWS)
• Familiarity with observability practices, including metrics, logging, alerting, and SLOs/SLIs
• Comfort participating in on-call and incident response with a structured approach to troubleshooting under pressure
• Strong written communication and the ability to operate as a manager-of-one in an async, distributed environment
• A track record of using automation, and increasingly AI, to reduce toil

Hiring Process

• Recruiter Screen: Discussion about your background, fit, and potential level/team
• Core Technical: Collaborative discussion covering system architecture and incident review
• Hiring Manager Interview: Conversation on ownership, judgment, execution, collaboration, and growth
• Peer Technical: Team-specific depth run by SREs from the prospective team
• Skip-Level Interview: Conversation with a senior leader on values alignment
