Lead the operation and evolution of production-grade Kubernetes clusters across cloud environments, making architectural decisions on upgrades, scaling, disaster recovery, and reliability improvements.
Define and drive GitOps strategy and standards across the organization, owning ArgoCD-based workflows (Application Sets, sync policies, deployment standards) and mentoring teams on GitOps best practices.
Architect and establish Terraform-based infrastructure-as-code standards, building reusable modules, managing state, and implementing drift detection for safe provisioning.
Lead platform observability strategy and incident response processes, standardizing monitoring and post-incident reviews to improve availability, performance, and resilience.
Partner with and mentor application teams to onboard services onto the platform, creating documentation, runbooks, and self-service tooling to scale and boost developer productivity.
Design and implement security control standards (RBAC, network policies, secrets management via Vault/Sealed Secrets/External Secrets Operator) to meet compliance and scale.
Drive integration of platform capabilities with CI pipelines (GitHub Actions, GitLab CI, Tekton) to establish end-to-end delivery workflows and standards.
