Manufacturing Engineer II (Mechanical)

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. 

This is an excellent opportunity for a talented Manufacturing Engineer to take the next step in their career, working on complex and challenging manufacturing engineering tasks with high accountability. 

The Opportunity 

As a Manufacturing Engineer II, you’ll be responsible for transforming complex designs into repeatable, high-quality production processes. You’ll take ownership of the manufacturing documentation and tooling for specific sub-assemblies, ensuring as-built hardware meets as-designed specifications. 

You’ll be comfortable working at pace and to a high quality, driving efficiency, safety and scalability. If you’re an experienced engineer looking for autonomy to deliver results on genuinely challenging and impactful projects, we’d love to hear from you. 

What you’ll be doing 

Responsibilities include: 

• Create, maintain and optimise accurate manufacturing documentation and system data (BOMs, work instructions, routings, work orders) in Manufacturo. 
• Document and standardise manufacturing processes to support scalability from prototype builds through Low-Rate Initial Production (LRIP). 
• Design or source specialised tooling, jigs, GSE, and support the selection and commissioning of new manufacturing equipment.  
• Assist the design team in Design for Manufacture and Assembly (DFM/A) for various manufacturing processes, E.g., metal additive manufacturing and Ceramic Matrix Composites. 
• Represent manufacturing in design reviews and part release activities, ensuring hardware is optimised for assembly, cost, and lead time. 
• Evaluate hardware non-conformances and define dispositions (Rework, Use-As-Is, or Scrap)  
• Contribute to Failure Mode and Effects Analysis (FMEA) for manufacturing processes. 
• Act as a technical interface with outsourced manufacturing suppliers, ensuring technical requirements are clearly communicated, and vendor quality issues are resolved.  
• Develop and maintain manufacturing test procedures; support production test campaigns and troubleshoot test failures. 

Life at Hypersonix  

We are a 50-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. 

You will thrive here if you:

• Own problems end to end without waiting for a complete picture 
• Can hold technical rigour and program pace simultaneously – without sacrificing either 
• Lead by bringing people with you, not by working around them 
• Stay solutions-focused when the ground shifts under you. 

What You’ll Bring 

To hit the ground running in this role, you’ll need: 

• A bachelor’s degree in mechanical, aerospace, or manufacturing engineering or related discipline. 
• 3+ years’ experience working in a high-precision manufacturing environment (aerospace, defence, medical, automotive, or similar).  
• Experience working in MRP, MES, or ERP systems (ideally Manufacturo or similar). 
• Demonstrated experience writing manufacturing procedures, work instructions, or process documentation. 
• Experience designing or specifying tooling, jigs, or fixtures for production. 
• An ability to read and interpret engineering drawings and GD&T. 
• Strong analytical and problem-solving skills with a practical, hands-on approach 
• An ability to translate complex engineering concepts clearly to technicians on the shop floor and to stakeholders at all levels. 
• An ability to obtain any applicable security clearance or background checks.  
• Right to live and work in Australia.  

Bonus points if you have experience with: 

• Manufacturing, engineering, or aerospace industries 
• Production test procedure development and execution 
• CNC machinery (mill, lathe, waterjet, laser cutter, EDM)  
• CAD (NX & Teamcenter)    

Ready to Fly Faster? 

If you want to do the most technically challenging work of your career — and you’re honest with yourself that our environment will enable you to do your best work — we’d love to hear from you.  

Benefits include: 

• Competitive salary 
• Equity participation 
• Flexible working – we care about output, not hours 
• A team doing genuinely world-class work. 
• Real ownership and influence from day one 
• Funded Professional development 
• Confidential Employee Assistance Program
