  • Designing secure patterns for Workload Identity Federation to remove the need for long-lived credentials.

  • A strong understanding of the core concepts of Identity (IAM) and Infrastructure as Code is essential.
  • You bring proven capability in designing and maintaining reusable Terraform modules that codify IAM controls.
  • Proficiency in at least one scripting language, such as Python, alongside an automation-first mindset.
