An overview of this role As a Senior Engineer on the Runway team, you'll lead the design, evolution, and operation of the Kubernetes-based platform and developer tooling that powers Git Lab's engineering organization. You'll drive strategic infrastructure initiatives across platform architecture, automation, and developer experience. That includes operating production Kubernetes clusters across cloud environments, scaling our ArgoCD-based Git Ops workflows, and setting infrastructure-as-code practices and standards across teams.

You'll mentor engineers, influence architectural decisions, and drive platform improvements that enhance reliability, observability, and security controls like RBAC and secrets management. Your work will establish clear patterns that make it easier for application teams to adopt modern practices and ship with confidence.

Some examples of our projects:

Evolve ArgoCD Git Ops standards across environments (Application Sets, sync policies, and deployment guardrails)
Build reusable Terraform modules and practices for safe, repeatable cloud infrastructure provisioning and drift detection

What you'll do Manage and evolve production-grade Kubernetes clusters across cloud environments, contributing to architectural decisions on upgrades, scaling, disaster recovery, and reliability improvements.

Implement and maintain Git Ops workflows using ArgoCD, including Application Sets, sync policies, and deployment standards, and share best practices with teams adopting these patterns.

Build and maintain reusable Terraform modules that enable safe, repeatable cloud infrastructure provisioning, including state management and drift detection practices.

Lead incident response, drive post-mortems to clear conclusions, and implement improvements to availability, performance, and resilience as part of on-call rotation.

Partner with application teams to onboard services onto the platform, writing documentation, runbooks, and self-service tooling that improves developer productivity.

Implement security controls such as RBAC, network policies, and secrets management that meet compliance requirements.

Contribute to CI pipeline integrations as part of end-to-end delivery workflows.

What you'll bring Proficiency in Go for writing and maintaining production-grade services and automation tooling, with the ability to guide others on best practices and code quality. Python or Bash experience is a plus.
