• Capable of handling multiple tasks, setting priorities and meeting schedules.
• Demonstrated capability to perform engineering analysis and familiarity with commonly used analysis tools (e.g. FEA, DFX, etc).
• Understanding of tolerance analysis and GD&T application.
• Capable of designing/ debugging complex electro‑mechanical products.
• A self‑starter and must be able to work independently with minimum supervision or direction.
• Open‑minded and data‑driven; willing to entertain other options when presented with superior technical evidence or analysis.
• U.S. work authorization and ability to travel occasionally as required.

Education/Experience

• A BSME/MSME from a regionally accredited and non‑profit institution.
• 8+ years of mechanical engineering experience in product development.
• Demonstrated experience developing products from concepts through design, testing, manufacturing launch, and market release.
• Strong experience with component and subsystem design, including creation of detailed manufacturing drawings and GD&T.
• Experience conducting engineering analysis, tolerance stack‑ups, design verification testing, and root cause investigations.
• Experience with releasing mechanical products to production via a structured new product development process is desirable
• Experience with manufacturing processes (i.e. Injection Molding, Extrusion, Metal Forming & Stamping) is desirable.
• Experience integrating industrial design and human factors in design is desired.
• Ability to communicate effectively in English.
