• You have meaningful production experience with Kubernetes or EKS, including cluster lifecycle management, upgrades, workload delivery, container security, observability, and runtime controls
• You are a trusted technical escalation point who can diagnose complex infrastructure issues across networking, DNS, IAM, Kubernetes, CI/CD, security controls, and application delivery
• Strong track record of owning production changes from design through implementation, validation, documentation, incident support, and long-term operational maintenance
• You balance strong technical opinions with sound judgment, humility, and openness to feedback, and you can explain infrastructure decisions and tradeoffs to both technical and non-technical partners
• Hands-on experience using AI tools to accelerate infrastructure work, improve output quality, and reduce operational toil, and you help colleagues apply them responsibly while maintaining appropriate security, validation, and human oversight
• Experience supporting infrastructure in a regulated financial-services environment
• Experience with PCI DSS, CIS controls, security audits, evidence collection, or remediation programs
• Experience migrating workloads or connectivity from data centers to AWS
