• Integrate Terraform and infrastructure deployment into GitLab CI/CD pipelines.

• Contribute to observability and operational readiness (monitoring, logging, metrics, scaling).
• Keep cost optimisation in mind when designing infrastructure.

Ideally, you’ll have/be:

• 5+ years of hands-on DevOps experience.
• Strong experience delivering AWS infrastructure at scale (multi-account, multi-region).
