- Create accurate 3D models, assemblies and production-ready drawings using SolidWorks.
- Improve existing products for performance, reliability, manufacturability and cost.
- Complete engineering calculations, design reviews, tolerance analysis, material selection and design validation.
- Prepare and maintain bills of materials, specifications, drawing registers and manufacturing documentation.
- Support prototyping, testing, certification and the introduction of new products into production.
- 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

- Bachelor’s degree in Mechanical Engineering or a closely related discipline.
- Minimum five years’ experience in mechanical design, product development or a comparable engineering role, preferably in manufacturing.
- Strong SolidWorks capability, including complex parts, assemblies and detailed manufacturing drawings.
- Sound knowledge of mechanical design, materials, tolerances and manufacturing processes.
- 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.
- 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.
- Genuine ownership of projects, with the scope to introduce new ideas and engineering improvements.
