Job Description

Staff Cloud Platform Engineer

Sydney | Full-time | Hybrid

(AU Citizenship required)

The Mission
At the edge of quantum computing and cloud architecture, this team builds the infrastructure that keeps it all running. Their systems power GPU-accelerated workloads, real-time modeling, and research-grade simulation at scale.
This is the layer that turns deep science into reliable software.

They’re now looking for a senior engineer to shape that platform’s next chapter. Someone who can think strategically, lead technically, and leave the place stronger than they found it.

What You’ll Do

  • Architect and evolve a Kubernetes-based multi-cloud platform that supports high-performance computing workloads

  • Lead technical decisions across architecture, standards, and implementation, balancing innovation with reliability

  • Define and execute a roadmap for CI/CD, developer tooling, and Infrastructure-as-Code frameworks

  • Guide cloud engineering strategy across multiple teams and help define patterns for scalability, observability, and security

  • Mentor engineers, establish technical excellence, and raise the overall bar for platform quality

  • Build golden paths that make delivery faster, safer, and more predictable

  • Stay hands-on enough to troubleshoot, design, and refine alongside the team

What You Bring

  • 7+ years in Platform, DevOps, or Site Reliability Engineering

  • Deep experience building and managing Kubernetes in production

  • Expert knowledge of AWS, GCP or Azure, including Infrastructure-as-Code practices

  • Strong background in Linux systems, automation, and troubleshooting

  • Programming fluency in Go, Python, or JavaScript

  • Proven ability to lead technical strategy and communicate clearly with senior stakeholders

  • A steady approach to innovation — thoughtful, evidence-based, and grounded in real engineering needs

Bonus Points

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

  • Experience with GitOps tooling such as Argo CD or Flux CD

  • Familiarity with CNCF projects and open-source community practices

Why It Matters
This platform underpins software used by scientists, engineers, and customers around the world. Reliability here isn’t a feature — it’s the foundation.
The work is complex and strategic, blending architecture with mentorship and hands-on engineering. You’ll help set the standard for how high-performance systems are built, scaled, and maintained.

The Opportunity

  • Shape the technical direction of a globally deployed cloud platform

  • Influence culture and engineering practice across multiple teams

  • Work alongside senior engineers, researchers, and product builders in one of Australia’s most advanced tech environments

  • Competitive salary, equity, and flexible working arrangements
