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.
We’re looking for a commercially minded Legal Counsel to take on a newly created role within Hypersonix. Reporting to our General Counsel & Company Secretary, you’ll have the autonomy to run your own matters, whilst working directly with engineers, executives and external partners. You’ll deliver practical legal advice that helps us make good decisions and move quickly.
If you're looking for a role where you can take ownership, build broad commercial experience and make a visible impact in a growing company, this could be the opportunity for you.
We can consider part-time for this position (minimum 25hrs per week).
We're a 70-person company moving fast in one of the most demanding fields in aerospace. The pace is fast, expectations are high and the environment is constantly evolving. The people who thrive here are energised by that — not unsettled by it.
To thrive here, you’ll need to embrace change, stay resilient, and bring a proactive, solutions-focused mindset. Priorities shift fast — you'll need to adapt just as fast and genuinely enjoy the pace rather than just tolerate it. You'll be part of a tight-knit team delivering bleeding-edge solutions under real deadline pressure, so strong problem-solving instincts and flexibility aren't nice-to-haves — they're how the work gets done.
To hit the ground running in this role, you’ll need:

Hypersonix Launch Systems builds and operates hydrogen-fuelled scramjet powered autonomous aircraft for a range of government, defence, aerospace, and commercial customers.
The first hypersonic flyer to launch is DART AE (Additive Engineering). DART AE is a 3.5 metre long hypersonic aircraft that is powered by a single SPARTAN scramjet engine and makes significant use of 3-D printed high temperature metal alloys. It uses hydrogen fuel and will fly at Mach 7.
The launch is part of the HyCAT program by the Defense Innovation Unit. Hypersonix was the first company to be selected for the program in March 2023, targeting a first launch for Q1 2026 in the United States.
Hypersonix is revolutionizing hypersonic flight technology with a cloud-based software-as-a-service digital twin. By combining extensive knowledge and data from atmospheric flight tests, this virtual replica accurately predicts real-world outcomes. It allows rapid and repetitive testing of materials, designs, manufacturing techniques and enables global 3D printing of components through secure additive manufacturing.
Hypersonix product road map also includes VISR, a high-speed suborbital Intelligence, Surveillance and Reconnaissance (ISR) and rapid airfreight flyer demonstrator as well as Delta Velos Orbiter for small satellite launch in a non-ballistic trajectory.
