• Experience with rapid iteration and prototyping
• Advanced proficiency in 3D design tools such as AutoDesk suite (Inventor, Fusion), SolidWorks, etc.
• Strong knowledge of manufacturing principles and DFM/A
• Strong knowledge of thermomechanical FEA, and experience using FEA software (Inventor FEA/Nastran, Comsol or Ansys etc.)
• Good knowledge of GD&T and tolerance stack-up

PREFERRED QUALIFICATIONS

• Good understanding of fluid dynamics
  Strong knowledge of heat transfer, and thermodynamics
• Experience with machine design
• Background in materials science with experience in shape memory alloys
• Experience in an agile research and development environment
• Experience with laser processing and advanced manufacturing

WHAT WE OFFER

• A full-time, permanent position working in a state-of-the-art facility
• Flexible work schedule (40 hrs/week) with core hours between 10:00am – 3:30pm
• Competitive salary, commensurate with experience
