Make self-managed GitLab upgrades reliable across Omnibus, Helm Charts, and the GitLab Operator
GitLab's Upgrades team needs a senior backend engineer to harden the deployment tooling, including Omnibus GitLab, Helm Charts, the GitLab Environment Toolkit, and the GitLab Operator, that self-managed customers rely on to install and upgrade GitLab reliably. Expect deep questions on Kubernetes/Helm operations, Go service design, infrastructure-as-code, and reducing upgrade failure and escalation rates for enterprise-scale deployments.

Common question themes
Walk me through a deployment or upgrade pipeline you owned and how you measured and improved success rate or reduced escalations
Describe a resilient, observable Go service you built and what made it debuggable across environments you don't directly control
How have you used Terraform to manage infrastructure across a cloud provider, and what tradeoffs did you hit
Tell me about diagnosing an operational pain point for self-managed or on-prem customers and how you fixed the workflow
How do you approach PostgreSQL troubleshooting in a secure, scalable production setup
Describe how you've mentored a backend engineer or influenced architectural direction on your team
