Financial Controller

We’re building aircraft that fly faster, further, and to space.

Hypersonix is an Australian aerospace engineering and advanced manufacturing company building hydrogen-powered scramjet aircraft. We work at the bleeding edge of hypersonic technology, delivering aircraft that fly faster, reach further, and open new pathways to space – and we’re a small, highly capable team doing work that genuinely matters.

The Opportunity

As our Financial Controller, you’ll play a key role in safeguarding the integrity of our financial operations, reporting, compliance and controls as we continue to scale. Working closely with the CFO and FP&A Manager, you’ll lead day-to-day finance operations, deliver accurate and timely financial insights, and support executive decision-making across the business. You’ll also guide and develop the finance team, driving a culture of accuracy, accountability and continuous improvement.

This role would suit someone who’s recently moved into a Financial Controller position, or someone looking to step up from a Senior Financial Accountant. This is a rare opportunity to join a company working with cutting-edge hypersonic technology, directly supporting our teams to deliver exceptional engineering. If you thrive in a fast-paced, scaling environment and want to be a part of our journey, we’d love to hear from you.

Please note that this is a temporary position and will be offered as a 6 – 12 month fixed-term contract.
