  • Apply strong Linux and/or Windows systems engineering knowledge
  • Support OS-level hardening, patching, access control, and troubleshooting
  • Understand how cloud infrastructure maps to underlying OS and network behavior
Required Qualifications:
  • Senior-level experience designing and operating AWS infrastructure at scale
  • Hands-on experience with AWS Organizations, Control Tower, and multi-account architectures
  • Proven experience migrating workloads from single-account to multi-account AWS environments
  • Strong Linux and/or Windows OS fundamentals

  • Infrastructure as Code using Terraform
  • Experience implementing security guardrails (SCPs, IAM, KMS)
  • Experience with centralized logging, monitoring, and security tooling
  • Experience with AWS cost management and chargeback/showback models
