Tasks

• Implement and operate Kubernetes infrastructure (AKS): cluster lifecycle, networking, resource management, auto-scaling, and multi-tenancy patterns.
• Build and maintain CI/CD pipelines using GitHub Actions and ArgoCD for automated testing, container builds, and GitOps deployments.
• Develop Infrastructure as Code (Terraform, Bicep) to provision and manage Azure resources with consistency and auditability.
• Operate container registries (ACR), artifact management, and image security scanning workflows.
• Implement and maintain observability infrastructure: Azure Monitor, Application Insights, Prometheus, Grafana—including dashboards, alerting, and distributed tracing.
• Manage async processing infrastructure: Celery workers, Redis queues, and workflow orchestration patterns supporting AI agent execution.
• Implement platform security controls: network policies, pod security standards, Key Vault integration, RBAC, and private endpoint configurations.
• Support database infrastructure: PostgreSQL management, backup/recovery, connection pooling, and performance tuning.
• Create self-service tooling and templates that enable development teams to deploy and operate services with minimal friction.
• Diagnose and resolve infrastructure issues across clusters, pipelines, and cloud services; perform root-cause analysis and implement preventative improvements.
• Collaborate with Platform Architects, Backend Engineers, and ML Engineers to translate architecture designs into reliable infrastructure.
