• Extensive production experience operating Kubernetes (EKS strongly preferred) at scale.
• Strong Linux systems engineering skills and advanced scripting in Python, Bash, or Go.
• Deep expertise in CI/CD platforms (GitHub Actions, ArgoCD, Jenkins).
• Expert-level understanding of cloud networking and security.
• Proven experience designing and operating observability platforms at organizational scale.
• Strong experience with database infrastructure (Aurora PostgreSQL, RDS, ElastiCache/Redis, OpenSearch, DynamoDB).
• Demonstrated ability to lead disaster recovery planning and design HA architecture.
• Excellent technical communication skills.
• Proven track record of mentoring engineers.
