What You Will Do

• Lead, mentor, and develop a Cloud DevSecOps/SRE team focused on cloud applications (AI, MLOps, Data).

• Build, standardize, and maintain CI/CD pipelines and GitOps processes (Jenkins, GitLab CI, ArgoCD).

• Develop and manage Kubernetes environments (Anthos, OCP, Istio, Helm).

• Expand the Infrastructure as Code (IaC) platform for rapid, repeatable cloud provisioning (Terraform).
