Job Description
We're building aircraft that fly faster, further, and to space.
n
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.
n
The Opportunity
n
As Lead Propulsion Engineer, you'll lead a team of scramjet propulsion and fluid systems engineers working across the full engineering lifecycle – taking ownership of the fuel and engine
n
systems that power our hypersonic flight vehicles and their support equipment.
n
This is a hands‐on leadership role. You'll combine line management, technical mentoring and career development for engineers at every level of experience - with review and approval of propulsion and fluid systems engineering artefacts. As our propulsion and fluid systems subject matter expert, you'll provide direction and advice across the whole engineering team.
n
What You'll Own
n
n
Act as subject matter expert across the whole engineering team, driving design reviews and failure investigations, and collaborating with engineers and designers to deliver high-performing propulsion and fluid systems.
n
Lead review and approval of engine, fuel, and fluid system designs for hypersonic vehicles and ground support equipment
n
Own propulsion and fluid systems design integrity, reviewing and approving engineering artefacts, engine and fluid system designs, and ensuring rigorous Design for Manufacture, Reliability, and Failure Modes Effects Analysis
n
Guide technical execution, directing your team's use of CFD, thermal,



and structural analysis tools across the full engineering lifecycle — from concept through design, test, and in-service support
n
Push our technology forward, contributing directly to next-generation propulsion technology and process improvement.
n
Lead and develop the team – line management, technical mentoring and career development, guiding use of CFD, thermal, and structural analysis tools.

Life at Hypersonix
n
We're a 60-person company moving fast in one of the most demanding fields in aerospace. Our culture values creative thinking and practical solutions that get results. You'll work alongside a passionate, collaborative team in an environment built on flexibility and trust rather than rigid timekeeping.
n
To thrive here, you'll need to embrace change, stay resilient, and bring a proactive, solutions-focused mindset. Priorities shift rapid — 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.
n
What You Bring
n
To hit the ground running in this role, you'll need:
n
n
Bachelor's degree in mechanical, aerospace, chemical or
n
propulsion-related Engineering
n




CPEng / RPEQ (held or working toward)
n
5+ years in propulsion, fluid systems, combustion, or thermal-fluid design — ideally with exposure to scramjet or high-speed air-breathing propulsion or closely related
combustion/aerothermodynamics
n
Proven experience leading a team of engineers, with a hands‐on, collaborative leadership style
n
Experience in configuration management and Product Lifecycle Management systems for propulsion/fluid system designs and CAD data.
n
Excellent communication skills – you can break down complex technical concepts clearly for any audience, and you speak clearly and concisely.
n
Sharp attention to detail and organisational skills, managing multiple projects and deadlines at once.
n
Ability to obtain any applicable security clearance or background checks.
n
Right to live and work in Australia.
n
n
Bonus points:
n
hypersonics experience, a Master's/PhD in propulsion or combustion, hot-fire test campaign experience, hydrogen or cryogenic propellant systems knowledge, or hands-on Siemens NX / Teamcentre skills.
n
Why Hypersonix?
n
You'll be working on hardware that already flew — DART AE, our hydrogen-fuelled scramjet demonstrator, completed a real flight test this year. This isn't a paper study. We are a fast-moving team building things that don't exist anywhere else in the world, with your name on the propulsion system that gets it there.
