Your Impact

Requirements

• Kubernetes Mastery: Expert-level experience managing production K8s workloads (preferably within GKE, but will also consider EKS). Deep understanding of Networking, Storage, and RBAC.
• CI/CD & GitOps: Hands-on expertise with ArgoCD and modern pipeline runners (GitHub Actions, GitLab CI, or Jenkins).

• Modern Workflow: Experience (or strong desire) using AI-pair programming tools like Cursor and Claude to multiply personal and team productivity.

Responsibilities

• Infrastructure Leadership: Architect and oversee large-scale Kubernetes clusters in GKE, ensuring high availability, performance tuning, and cost optimization.
• GitOps & Orchestration: Design and refine complex CI/CD lifecycles using ArgoCD, moving toward a fully declarative infrastructure-as-code model.
