Hands-on senior engineer responsible for designing, operating, and evolving production Kubernetes platforms on AWS EKS. Owns platform epics end-to-end and provides technical direction across a shared backlog. This is a senior individual contributor role, not a people-management post.

• Deliver GitOps-based deployments (ArgoCD / Flux)
• Build and manage Infrastructure-as-Code using Terraform
• Operate and improve platform reliability and production support
• Partner with application, security, and architecture teams
• Provide technical leadership through design reviews, pairing, and mentoring

Required Experience

• Deep, hands-on Kubernetes production experience (EKS strongly preferred)
• Strong knowledge of K8s networking, security, and multi-tenancy
• Proven experience with Terraform and CI/CD pipelines
• GitOps delivery experience (ArgoCD / Flux)
• Strong AWS background (Azure/GCP a plus)
• Solid networking fundamentals (VPC, CIDR, routing, firewalls, DNS)
• Confident with Linux CLI, Bash, and Python

Nice to Have

• CNCF tooling: Cilium, Kyverno, Karpenter, Helm, Prometheus
• Internal Developer Platform / self-service platform experience
• Multi-cluster or hybrid cloud environments
