- Coordinate with machine shops, contract manufacturers, and vendors to execute fabrication and validate designs
- Conduct hands-on testing and identify improvement opportunities for performance, reliability, and usability
- Establish requirements, priorities, and execution plans in collaboration with internal stakeholders
What they're looking for
- Mechanical CAD design and modeling
- Manufacturing processes and fabrication constraints
- Rapid prototyping (3D printing, machining, sheet metal, casting)
- Project management and multi-tasking
- Hands-on prototyping and assembly
- Vendor and machine shop coordination
- Product testing and validation
- Mechanical engineering fundamentals
