- Evolve AWS infrastructure and network architecture (VPCs, subnets, IAM, account structure) to support scalable, multi-team workloads
- Build and maintain infrastructure-as-code and GitOps workflows using tools such as Terraform, CDK, and ArgoCD
- Improve platform reliability and performance by defining and driving SLOs, analyzing incidents, and implementing systemic fixes
- Participate in and help improve the on-call rotation, leading incident response and post-incident reviews to drive systemic platform improvements
- Partner with SRE, Delivery, InfoSec, and product/ML teams to land high-impact infrastructure changes and platform standards
- Drive improvements in developer experience by simplifying platform usage, reducing toil, and enabling faster product and ML development
- Contribute to cost efficiency initiatives by optimizing resource utilization across Kubernetes and cloud infrastructure
Requirements:
