• Develop Production Automation: Write robust, maintainable code using Python and Terraform/CloudFormation for CI/CD pipelines, custom tooling, and automated deployment scripts.
• Ensure Enterprise Security: Implement and maintain high-security standards, firewalls, encryption, and network segregation across the multi-account AWS architecture.
• Enable Velocity: Build self-service infrastructure capabilities for engineering teams, fostering independent resource provisioning and scaling.

Required Experience:

• 5+ years of infrastructure/DevOps experience with deep, hands-on expertise managing complex, multi-cluster Kubernetes deployments.
• Proven production experience with Karpenter, Flux, and Kustomize.
• Expert knowledge of AWS and managing complex multi-account architectures for security and scalability.
• Strong coding skills in Python for automation and tooling, alongside extensive use of Terraform or CloudFormation.
• A demonstrated ability to build simple, elegant solutions to complex distributed systems challenges.
