  • Experience designing and shipping production systems end-to-end.
  • Hands-on experience with AWS infrastructure and security primitives (IAM, networking, RDS, etc.).
  • Experience with infrastructure-as-code tools like Terraform.
  • Familiarity with identity systems such as SSO, IAM, or IdPs.
  • Strong communication skills and the ability to drive projects independently.
