Title: Principal Platform Engineer
Duration: 6 month rolling contract
Location: Sydney (WFH hybrid)

Join the platform team behind one of Australia's largest and most successful businesses - supporting 30 million monthly active users. This is a hands-on principal role where you'll set technical direction, own the architecture, and still ship code.

The role is split evenly across strategy, architecture and implementation; setting technical direction, owning the platform's architecture, and staying hands-on enough to build reference implementations yourself. Azure is the primary cloud with a growing GCP footprint, so genuine multi-cloud depth matter.

You must have:

- Production Kubernetes at scale — hands-on with both AKS and GKE




- Genuine multi-cloud experience — strong Azure plus real GCP
- GitOps delivery expertise — Harness GitOps and the Argo suite (ArgoCD, Argo Rollouts, Argo Events)
- Infrastructure as Code — Terraform and Crossplane, including landing zone design
- Built or run an internal developer platform — Backstage and/or Cortex
- Robust production-grade Go and Python — shipping operators and platform services, not just diagrams
- Cell-based or microservice architecture in multi-tenant environments
- Principal-level track record setting platform strategy and technical direction
