Job Description:

We are looking for an enthusiastic and inquisitive Platform Engineer to help strengthen our platform engineering capabilities and improve the supportability, observability, and documentation of our infrastructure. You will ensure that infrastructure, connectivity, and shared service dependencies are fully mapped, documented, and efficiently supported. You will play a central role in enabling engineering teams by developing and maintaining cloud-native infrastructure, CI/CD pipelines, and operational tooling, with a particular focus on standardising support processes and improving cross-team efficiency. The role is highly collaborative, supporting teams with scalable, secure infrastructure patterns, and shared operational capabilities. You will work with GCP native technologies along with Terraform and Azure DevOps, and contribute to a platform-first engineering culture that values quality, automation, and continuous improvement.

Ensure pipelines include infrastructure validation, environment promotion, and automated testing stages
Collaborate closely with engineering squads, architecture, governance, and security teams to deliver shared platform outcomes
Contribute actively to Squad, Chapter, and Guild forums, raising platform standards and sharing reusable patterns
Help onboard and support teams using platform infrastructure, ensuring consistent adoption and support coverage
