- Own AWS EKS clusters and Kubernetes workloads, including autoscaling (Karpenter), FluxCD -based GitOps, Helm charts, and custom SDKs for reusable deployments.
- Design and manage core cloud services—VPCs, VPNs, IAM, S3, RDS, ECR, load balancing, and network security controls.
- Build, maintain, and document infrastructure templates and developer enablement tooling to allow teams to deploy independently.
- Implement observability and monitoring systems using Grafana, Prometheus, and Loki for infrastructure and application metrics.
- Establish and contribute to CI/CD best practices using GitHub Actions and related automation pipelines.
- Participate in on-call rotations and respond to infrastructure alerts, RFIs, and external requests.
- Author and review technical design documents and proposals for infrastructure initiatives, architecture changes, and new services.
