Senior Mechanical R&D Engineer

About Syenta 

Syenta is pioneering a new era in semiconductor manufacturing with our groundbreaking Localised Electrochemical Manufacturing (LEM) technology. Our platform enables advanced packaging by combining patterning and metallisation into a single tool. We achieve high-speed, high-resolution metallisation at lower costs and energy use, while minimizing emissions and waste. 

Founded in Australia, we are building a world-class team of engineers and scientists tackling some of the toughest challenges in semiconductor manufacturing. Our collaborative, people-first culture empowers individuals to take ownership, innovate, and deliver breakthrough results. 

About the Role 

We are seeking a Senior Mechanical R&D Engineer to lead the end-to-end mechanical design of our custom semiconductor manufacturing machines. This role owns the full machine design lifecycle – from concept through detailed design, prototyping, validation, and production-ready equipment. 

The ideal candidate has a proven track record of taking machines from blank page to operational production equipment, thrives in a fast-paced, startup environment, and brings a broad skillset across mechanical systems, materials, and manufacturing processes. You will collaborate closely with controls, mechatronics, and software engineers to deliver integrated, high-performance manufacturing solutions. 

This is a high-impact role, critical to scaling Syenta’s in-house production capabilities and reducing reliance on external vendors.

• Conduct tolerance analysis, FEA, and other engineering analyses as required 
• Support prototyping, commissioning, and continuous improvement of equipment 
• Contribute to design reviews, documentation, and mechanical engineering standards 

Collaboration & Cross-Disciplinary Integration 

• Work closely with mechatronics, controls, and software teams to deliver fully integrated machine solutions 
• Communicate mechanical design decisions effectively across teams and stakeholders 
• Provide technical guidance and input on equipment architecture and systems integration 

Process & Standards 

• Establish mechanical design standards, best practices, and workflows for the team 
• Maintain high-quality documentation, including CAD, drawings, BOMs, and specifications 
• Support continuous improvement of design and manufacturing processes 

Requirements 

• Bachelor’s degree in Mechanical Engineering or equivalent 
• Proven R&D background with a track record of taking concepts from blank page to working hardware 
• Proficient in 3D CAD; platform agnostic (OnShape experience advantageous) 
• Engineering drawings to ISO 2768 
• Fluent in GD&T tolerancing – ASME Y14.5 and/or ISO GPS 
• Tolerance stack analysis 
• Pneumatics design and component selection 
• High-precision linear and angular motion system design 
• Material specification and selection 
• Design for Manufacture and Assembly (DFM/DFA) 
• Rapid prototyping experience 

Preferred Qualifications 

• Material selection experience in clean-room contexts 
• Experience with micro-fluidics and viscous flows 
• Clean-room practices; design for cleanliness 
• Experience working with metrology frames and vibration-isolated structures 
• Experience in startups or fast-paced engineering environments 
• Experience with simulation and analysis tools (FEA, tolerance analysis) 
• Familiarity with PLM systems, JIRA, or Confluence
