About this Opportunity
Firmus Technologies
Firmus Technologies is a global leader pioneering the development and operation of efficient AI infrastructure across Asia Pacific.
Founded in Australia in 2019, our mission is to create the most efficient AI infrastructure by combining cutting-edge technology with a steadfast commitment to sustainability.
At Firmus, we are unique in our approach. We design, build, and operate a new class of digital infrastructure – the AI Factory. Through our model-to-grid technology approach, we have pushed the boundaries of multi-generational liquid cooling systems, energy management, AI software orchestration, and construction. For our customers, this approach allows us to make every watt count and deliver low-cost AI tokens globally.
Firmus AI Cloud
Our large-scale GPU cloud platform, Firmus AI Cloud, is purpose-built to deliver energy-efficient AI compute at scale to customers.
It empowers developers, enterprises, educational institutions, and government users to train and deploy AI models with unmatched efficiency and cost savings. With an ever-growing suite of services and applications, we are committed to delivering a cloud experience that is market-leading, proprietary, and built to scale.
ROLE SUMMARY
Firmus Technologies is seeking a Senior Security Engineer, AI Platform and Infrastructure for our Engineering and Technology team. Customers provision GPU compute through API and console, software engineers build against it, our infrastructure engineers build the bare metal, virtualisation layer and Kubernetes clusters behind it, and our operators run the platform through the same control plane. You own both layers of Firmus AI Cloud: the platform control plane that engineering teams built, and the bare-metal infrastructure it runs on. Automation is how you scale that ownership.
