Job description

• Own and evolve our multi-cluster EKS infrastructure - from day-to-day operations to cluster upgrades, node group strategies, and capacity planning.
• Keep our Terraform and Terragrunt codebase clean, scalable, and ahead of the growing infrastructure needs - including refactoring and setting patterns others follow.
• Be the go-to person for Kubernetes internals - troubleshooting hard problems, tuning performance, hardening security (RBAC, network policies, secrets management).
• Drive cost optimization as a first-class concern - identify waste, propose and implement improvements, and make cloud spend a conscious engineering decision.
• Partner with development teams to help them ship reliably - improving deployment pipelines, platform tooling, and the overall developer experience.
• Evaluate and introduce new tools and approaches when they genuinely solve a problem - we have the freedom to do this, and we use it deliberately.
• Contribute to observability: make sure we know what's happening in our systems before our users do.
