· Investigate product or manufacturing issues and develop practical engineering solutions.

· Contribute to the design and implementation of tooling, machinery, jigs, fixtures and manufacturing improvements.

· Work closely with production, workshop and management teams and liaise with Australian and overseas suppliers, toolmakers and testing organisations.

· Take ownership of projects and deadlines while balancing engineering quality, manufacturing capability, cost and customer requirements.

Essential experience and qualifications

· Ability to prepare accurate bills of materials, technical specifications and production-ready engineering documentation.

· Strong practical problem-solving, project management and communication skills, with a structured and methodical approach.

· Demonstrated ability to work independently,



solve complex engineering problems and take projects from initial concept through design, testing and production.

· Full Australian working rights.

What we offer

· Competitive salary of $125,000–$135,000 super, based on experience.

· A modern, purpose-built office and manufacturing facility in Pakenham.

· The opportunity to design real products and see them manufactured on site.

· Direct involvement in new product development, advanced manufacturing equipment and business growth projects.

· A collaborative role working closely with experienced engineering, production and leadership teams.
