Desirable experience
* Worked on systems where components needed to be designed for manufacturing and precise assembly/operating tolerances
* Design of high‑speed automated material transfer systems
* Designed robust, ruggedised and precision mechanical systems for 24/7 operation with minimal down time
* General understanding and hands‑on experience with workshop equipment
* Completed projects using rapid prototyping technologies such as 3D printing
* Designed low‑power automated systems and/or equipment, e.g. animatronics, vending machines, automated food or pharmaceutical production
* Worked with stepper motors, servo motors, automatic material handling systems
* Project management skills or certification
* Designed and assembled electronic circuits, electrical panels and/or PCBs
* Worked in an environment with hygiene and/or regulatory requirements, such as the food, cosmetics or medical sectors
* Competent with SolidWorks software
Personal attributes
* Energy, ambition and commitment to ensure the job gets done
* Honesty, integrity and openness to ensure we build a great company culture
