• Develop and enhance assembly processes for both new and existing products
• Create, release, and maintain process documentation including specifications and work instructions
• Specify and execute validation testing for new assembly processes
• Train operators and technicians on new and updated processes
• Establish and monitor process metrics (SPC) to track yield and failure modes in pilot production
• Contribute to new product line design with a strong focus on Design for Manufacture (DFM)
• Drive continuous improvement initiatives to reduce manufacturing cost, increase process efficiency, and enhance product quality across all assembly lines
• Support the transfer of new assembly processes to overseas production facilities
• Develop and transfer assembly processes for customised product variants
• Conduct regular audits of production processes, staff, and equipment
• Ensure all manufacturing equipment and materials handling comply with OH&S standards

Essential Education & Experience

• Degree in Mechanical Engineering or Materials Science, with strong understanding of manufacturing concepts, materials, and mechanical tolerances used in mechanical assembly
• Experience as a process or manufacturing engineer, ideally within a high‑technology manufacturing environment

Desirable Skills & Experience

• Minimum 5 years developing or designing processes/equipment for electro‑mechanical or mechanical assemblies
• Strong understanding of materials used in precision assemblies (low‑thermal‑expansion adhesives, metals, ceramics) and associated testing methods (tensile, shear, etc.)
• Solid knowledge of SPC, FMEA, and reliability standards
• Hands‑on experience in failure analysis techniques (cross‑sectioning, inspection); SEM and XRD experience highly desirable
