Senior AI Engineer (Kubernetes & Customised Scheduler)

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.

Why Firmus?

As an NVIDIA Cloud and Engineering partner in Asia Pacific, you will gain skills, experience, and exposure across the AI industry and be part of shaping what this industry looks like for decades to come.

We are founder-led, not a big corporate. Decisions happen fast, our leaders are accessible, and there's minimum bureaucracy between you and the work. Ownership comes early. Whatever your role, you will have a direct line to outcomes, helping shape how the business grows as we scale nationally across a long-term, large-scale roadmap.

Work alongside founders and experts in AI infrastructure, energy systems and next-generation compute.

What we build here has impact beyond the business. Our AI Factories are designed to operate as assets to the energy grid to actively strengthen the communities and regions they operate in rather than drawing from them.

Considering applying? You don't need a perfect background to join our team. If you're driven and curious, there's a path for you. We back our people to grow into new domains and take on challenges beyond their previous experience.

ROLE SUMMARY

The Senior AI Engineer will be a core builder of the AI & Applications team's Model-to-Grid product, designing, developing, and operating the Kubernetes-based workload orchestration layer for massive-scale AI factories. The role has a strong software and platform engineering focus: building a proprietary job scheduler that enables efficient, reliable, and policy-driven execution of training, fine-tuning, inference, batch, benchmarking, and agentic workloads across cutting-edge GPU systems, including NVIDIA NVL72 GB300-scale deployments and future-generation platforms such as VR200.

The proprietary scheduler is a central product differentiator. It must be network-topology aware and AI-factory-resource aware: making placement, queueing, prioritization, admission, and execution decisions based not only on nominal GPU availability, but also on GPU and NVLink/NVSwitch topology, node and fault-domain boundaries, RDMA and fabric health, storage locality and throughput, workload characteristics, capacity, power, thermal state, maintenance activity, and other operational constraints.

The resulting capability improves outcomes in two directions. For AI users, it provides better workload placement, lower queue times, higher GPU utilization, stronger job-success rates, improved end-to-end throughput, and faster time-to-results. For AI-factory and grid operators, it serves as a technical shock absorber by making demand more observable, controllable, schedulable, and responsive to infrastructure availability, system health, power, thermal, capacity, and operational conditions.

The role will work closely with other AI engineers, inference and optimization engineers, the Model-to-Grid product and program lead, Platform, Infrastructure, Security, and operations teams. It will turn scheduler product requirements into robust production capabilities, integrating Kubernetes, custom controllers, APIs, observability, automation, workload recipes, benchmark signals, and supporting platform services. The work will align with the architectural direction of NVIDIA DSX OS and AI Factory Blueprint concepts - co-designed, resilient, multi-tenant AI-factory operations, while delivering the organization's proprietary scheduler intelligence and differentiated Model-to-Grid capabilities.
