Senior Cloud Platform Engineer

Job Description

Senior Cloud Platform Engineer

Sydney | Full-time | Hybrid

(AU Citizenship required)

The Mission

Somewhere between quantum physics and cloud engineering sits a platform that keeps the impossible running.

This team builds the backbone for a new generation of compute, systems that need to be stable enough for science, fast enough for AI, and flexible enough to survive the future.

They don’t just keep the lights on. They make the impossible routine.

What You’ll Do

Build and scale cloud-native infrastructure that runs high-performance applications across multiple environments

Own production-grade Kubernetes clusters and the automation that keeps them healthy

Design Infrastructure-as-Code pipelines that deploy cleanly and predictably

Champion DevOps culture and guide engineers toward repeatable, cloud-agnostic systems

Balance reliability with speed through fast iteration and minimal firefighting

Stay curious, experiment with emerging tools and shape what the next version of the platform looks like

What You Bring

5+ years in Platform, DevOps or Site Reliability Engineering

Strong experience running Kubernetes in production

Proficiency across AWS, GCP or Azure , and a clear understanding of Infrastructure-as-Code

Strong in Go or Python , with solid Linux fundamentals

Comfort working across CI / CD, monitoring and observability stacks

A bias for clarity, speed and great engineering hygiene

Bonus Points

Certifications in Kubernetes (CKA, CKAD or CKS) or Cloud Platforms (AWS, GCP)

Experience with GitOps tooling such as Argo CD or Flux CD

Familiarity with CNCF projects and modern IaC workflows

Why It Matters

This is the infrastructure layer behind a new computing frontier.

The systems you design will power advanced simulation, control and sensing products used by researchers, engineers and governments worldwide.

It’s complex, demanding work, but you’ll see your impact in the way new technologies move from theory to reality.

The Opportunity

Shape the next iteration of a multi-cloud, high-performance platform

Work alongside physicists, engineers and software builders pushing into uncharted territory

Competitive salary, equity and strong growth upside

Flexible working setup focused on output, not hours
