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

Firmus Technologies is seeking a Principal Data Engineer to join our Engineering and Technology team. You will own the data architecture across the company, setting the standards, patterns, and technology choices our engineers build on as we scale the platform. Your influence spans the full data stack: streaming telemetry off GPU compute and cooling systems, the data lake feeding hardware failure prediction models, the AI-native layers powering agent-based workflows, and the governance layer that keeps it all secure, discoverable, and compliant. You will be one of the most senior technical voices for data at Firmus: you make the architecture decisions the organisation lives with long-term, and you stay hands-on on the problems that are too complex or too consequential to delegate.  

KEY RESPONSIBILITIES

• Data Architecture & Technology Strategy   

Own the data architecture across Firmus: the patterns, technology choices, and technical standards that teams build on. Make the build-versus-buy, storage-topology, and streaming-versus-batch decisions the organisation lives with long-term and own the outcomes they lead to. 

• Platform Build & Operations 

Build the core of the data platform hands-on: the real-time and AI data pipelines, the storage layer, and the transformation and semantic layers that serve BI tooling, internal analytics, and customer-facing reporting. Collaborate with the data engineers and platform engineers to deliver and operate streaming and batch ingestion from GPU telemetry, cooling sensors, billing, and incident sources, with clear reliability, schema-evolution, and latency SLAs. Data components run as infrastructure-as-code on the self-hosted, bare-metal Kubernetes. You own their deployment, quality, and storage cost, and work with platform engineers on backup, recovery, and incident response.
