- Operate GitOps release management through Argo CD, including promotion gates and automated rollback paths
- Maintain Terraform modules that provision cluster infrastructure and policy baselines reproducibly
- Extend custom tooling supporting the release process to reduce manual intervention

Requirements

- 3+ years of experience with Amazon Elastic Kubernetes Service (EKS) and Kubernetes
