• Develop infrastructure-as-code automation workflows using Terraform, Ansible, and PowerShell
• Implement GitOps practices for infrastructure and application deployment pipelines
• Design and manage persistent storage solutions for Kubernetes including CSI drivers, storage classes, and backup/recovery procedures
• Support FedRAMP, HIPAA, and FDA 510(k)-aligned infrastructure deployments with proper hardening and audit trails
• Develop and maintain systems documentation, architecture diagrams, and operational runbooks
• Participate in on-call rotation for critical systems infrastructure
