DevOps / CloudOps Engineer

Remote·Full-time·Infrastructure

Keep Lumina's production infrastructure boring, fast, and cheap. You'll own EKS, CI/CD, observability, and the cost curve — with full autonomy to pick the tools and standards that serve the team best.

What you'll do

  • Operate AWS EKS clusters: ALB ingress, node groups, IRSA, PV lifecycle
  • Own the GitHub Actions CI/CD pipeline and the deploy story
  • Manage infra as code with Terraform
  • Build the observability stack: logs, metrics, traces, alerting
  • Right-size clusters and drive down cloud cost

What we're looking for

  • 4+ years running production Kubernetes (EKS preferred)
  • Strong Terraform / HCL and AWS networking (VPC, ALB, IAM)
  • Experience with CI/CD on GitHub Actions or similar
  • Comfort debugging Linux, Docker, and networking issues end-to-end

Nice to have

  • Prometheus / Grafana
  • OpenTelemetry
  • FinOps and cost engineering
