Job Description

Join a Deep-Tech Adventure as a Tech Lead – Cloud, Kubernetes & High-Performance Systems

Hybrid : 3 Days in North Sydney | 2 Days WFH

Imagine joining a well-funded Australian deep-tech startup at the very moment it’s redefining how engineering teams build and scale cloud platforms. Backed by top-tier global VCs, and founded by leaders from Google, ROKT, and large-scale cloud systems, this is your chance to help shape a category-defining product from the ground up.

As a founding engineering hire, you won’t just write code- you’ll architect the platform, influence technical strategy, and work side by side with ex-FAANG engineers building distributed, high-performance systems. You’ll take ownership of large-scale backend systems, design the core distributed cloud platform, and tackle deep challenges in performance, scalability, resilience, and orchestration. You’ll mentor early engineers, set engineering standards, and collaborate closely with the founders on architecture and product direction.

What You Bring

• Extensive backend engineering experience with complex cloud or distributed systems
• Strong skills in Python, Go, or Java
• Deep cloud expertise (AWS ideal; Azure / GCP also valued)
• Experience with Kubernetes, containers, and cloud-native architecture
• Proven ability building high-throughput, low-latency, or performance-critical systems
• Excellent problem-solving skills and a builder’s mindset
• Bonus: background in cloud infrastructure or cybersecurity

The culture here is low-ego, high-ownership, and built on trust-no bureaucracy, just engineers solving real problems at pace. If you want to tackle complex engineering challenges, shape a platform that could define its category, and make a massive impact, this is the place to do the best work of your career.
