Senior Mechanical and Mechatronics Design Engineer

Senior Mechanical/Mechatronics Design Engineer - Product Automation Established Australian Manufacturer | Sydney Our client is a long-established Australian manufacturer, backed by a major ASX-listed group, with a genuine end-to-end engineering environment - concept, prototyping, testing, and mass production, all in-house. They're growing their New Product Development team and looking for a Senior Mechanical/Mechatronics Design Engineer to join the automation side of the business - designing the motor-driven mechanisms and electromechanical systems that sit at the heart of their product range. This role suits you if: You've designed with small electric motors and basic gearing/transmission systems - even off-the-shelf gearboxes you've specified and integrated, not necessarily custom gear design from scratchYou're comfortable working at the interface between mechanical and electronics - designing housings and structures that accommodate PCBs, motors, and wiring, and collaborating closely with electrical/firmware engineersYou've designed injection-moulded plastic housings or enclosures, ideally with IP-rating requirementsYou've owned mechanical designs end-to-end, from concept through prototyping, validation, and mass production releaseYou're genuinely hands-on - happy prototyping, testing, and problem-solving in the workshop, not just at a deskExperience working to formal standards or regulatory frameworks is a plus What you'll be doing: Designing motor-driven mechanisms and actuation systems - gearing, transmission, and drive componentsDesigning plastic housings and enclosures around electromechanical assemblies, working to IP-rating and environmental protection requirementsWorking closely with electrical and firmware engineers to integrate PCBs, motors, and wiring within your mechanical designsRunning and interpreting testing - cyclic, wear, environmental, and destructive — to validate designs before releaseApplying DFM/DFA thinking from day one, working with suppliers and manufacturing to get designs production-readyContributing to design reviews, mentoring where needed, and bringing structure to a growing engineering function What we're looking for: End-to-end product development experience - from concept through to mass production, not just CADStrong SolidWorks skills is ideal, not essentialComfortable working across plastics and mechanism/motor-driven designAutonomous and confident owning a project without heavy oversight - this is a senior role in scope and expectation, with real input into how the engineering function is run What's on offer: Competitive salary depending on experienceEnd-to-end product ownership in a well-resourced, in-house engineering environmentBacking and stability of an established ASX-listed groupA small, collaborative team with real influence over how it's run
