  • Strengthen IAM design, networking boundaries and security controls

  • Improve observability, alerting and operational readiness

  • Contribute to incident response processes and reliability practices

  • Integrate Terraform and infrastructure changes into GitLab CI/CD pipelines

  • Keep cost optimisation and data transfer considerations in mind

Ideally, you'll have/be:

  • 5+ years hands-on DevOps / cloud infrastructure experience

  • Strong experience delivering AWS infrastructure at scale (multi-account)

  • Expert-level Terraform skills, including module design and state management

  • Strong understanding of AWS networking, IAM and security design

  • Experience operating production systems in security-conscious environments
