Lead EKS Platform Engineer

We're looking for a Lead EKS Platform Engineer to take ownership of autoscaling, policy governance, and release automation for a Kubernetes environment hosted on Amazon EKS.

The deployment follows an AWS cloud-native approach, incorporating multi-architecture node pools and custom tooling.

• Set up Karpenter provisioners to manage node lifecycle and optimize sizing based on workload needs
• Confirm autoscaling performs correctly across multi-architecture node pools covering AMD64 and ARM64
• Create Gatekeeper constraints and constraint templates to enforce cluster-wide policies at admission time
• Set up mutating admission configurations to ensure policy defaults are consistently applied across namespaces
• Manage GitOps release processes using Argo CD, including promotion gates and automated rollback mechanisms
• Maintain Terraform modules to reproducibly provision cluster infrastructure and policy baselines
• Enhance custom tooling that supports the release process to minimize manual effort

Requirements

• Over 5 years of experience working with Amazon Elastic Kubernetes Service (EKS) and Kubernetes
• Strong expertise in Karpenter for managing node lifecycle and optimizing workload sizing
