Lead Mechanical Engineer

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. We're a small, highly capable team doing work that matters — and we're growing.
This is a rare opportunity to own the structural and mechanical integrity of a hypersonic vehicle program from the ground up.
The OpportunityAs Lead Mechanical Engineer, you will be the subject matter expert for airframes, wings, internal structures, actuators, mechanisms and ground support equipment — from concept through to qualification.
This is a hands-on technical leadership role. You will lead and develop a team of engineers, review and approve design and analysis artefacts, and provide expert direction across the broader engineering team. You'll also be central to ensuring our engineering processes are rigorous, current, and continuously improving.
What you’ll be doingResponsibilities include:Leading structural and mechanical integrity of Hypersonic vehicles and ground systems - airframes, wings, actuators, mechanisms, internal structures and GSE.Reviewing and approving mechanical designs and analysis for hypersonic vehicles and GSE. Ensuring designs are assessed for manufacturability, reliability and FMEA.Ensure adherence to engineering process and guidelines and continuous improvement or processes.Day-to-day management, mentoring and technical development of your team.Leading work package planning and resource allocation in line with program schedules.Contributing to new materials, technologies and structural methods that push the boundaries of what's possible.Acting as the structures and mechanisms voice in design reviews, non-conformance investigations and failure analyses.Life at Hypersonix We are a 60-person company growing fast in one of the most technically demanding fields in aerospace. The pace is fast, the expectations are high and the environment is still evolving. Priorities shift as the program evolves. Processes are maturing in real time. Some days the path forward isn’t clear, and you'll need to find it yourself. We don't say this to be dramatic — we say it because it's the reality, and the people who thrive here are energised by it, not unsettled by it.
