What you will do

• Own the architecture and evolution of core infrastructure supporting increasing traffic, data volume, and workload complexity.
• Design resilient AWS account, IAM, networking, multi-AZ, and multi-region architectures.
• Build and operate Kubernetes platforms, including cluster lifecycle, workload isolation, resource allocation, autoscaling, upgrades, and deployment reliability.
• Scale and optimize Aurora RDS for MySQL and Postgres through query tuning, indexing, capacity planning, replication, failover, and safe migrations.
• Improve reliability through observability, SLOs, disaster recovery, incident response, infrastructure-as-code, safe migrations, and cloud cost optimization.
• Build AI-assisted tooling for incident investigation, capacity analysis, runbook automation, anomaly analysis, and toil reduction with bounded permissions and auditable actions.
