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 Accounts Payable Manager, you’ll take ownership of our procure-to-pay and accounts payable functions, helping to build a best-practice finance function.

• Lead the end-to-end accounts payable function, ensuring the accurate and timely processing of supplier invoices, expenses, corporate cards and payments.
• Manage supplier relationships, vendor onboarding, payment runs and accounts payable ageing.
• Drive compliance and financial controls across the procure-to-pay process, ensuring adherence to Delegations of Authority, purchase order requirements and governance standards.
• Work closely with Procurement and budget holders to improve purchase-to-pay compliance, resolving supplier queries and payment disputes as required.
