• Serve in the on-call and incident-command rotation and drive retrospective follow-up work to completion
• Provision and maintain AWS accounts and ECS/EKS clusters, and right-size capacity to meet reliability targets
• Run and harden the network edge: CDN, bot protection, API gateway and WAF
• Design and test failover and recovery for compute, network and edge, including game days and DR exercises
• Apply infrastructure as code to production with guardrails, drift detection and safe rollback paths
• Apply and improve the rollout policy and safety gates, and partner with product teams on readiness
• Keep production patched and certificates current, and automate that work
• Maintain production security posture with Security, including least-privilege IAM and image and dependency scanning
• Mentor engineers through incident reviews, code review and pairing, and write runbooks

• Production experience with AWS and container platforms such as ECS, EKS or Kubernetes
• Solid Linux fundamentals, including patching, performance troubleshooting and container internals
• Strong networking fundamentals: TCP/IP, HTTP, TLS, DNS, load balancing and VPC design

• Sound judgment using AI tools, including validating AI-generated changes before they reach production
• Clear written and verbal communication, including explaining operational risk to engineers and non-technical partners

Nice to have

• Depth in more than one of the areas above

• Experience with a CI/CD system such as GitHub Actions, Harness.io, CircleCI or TeamCity
• Hands-on experience with Datadog, Sentry, Honeycomb, Rootly, Fastly or Kong
• Windows Server experience, since production includes a Windows fleet alongside containerized AWS services
