Qualifications

• Hands-on experience taking a physical product or subsystem from incomplete requirements through mechanical design, prototyping, debugging, and testing, with learning from real operating conditions.
• Strong mechanical design fundamentals, including materials and process selection, fit and tolerances, assembly, and reliability considerations.
• Proficiency with a mechanical CAD package such as SolidWorks, Creo, NX, or equivalent, and the ability to create drawings and specifications suppliers can use.
• Product judgment: question requirements, understand the customer problem, and explain technical choices in terms of cost, usability, performance, and business value.
• Able to operate independently through ambiguity, prioritize work, and communicate decisions and risks clearly.
• Experience collaborating with suppliers or manufacturing partners and with engineers from other disciplines.
• Bachelor's or Master's degree in Mechanical Engineering or related field, or equivalent practical experience.
• Comfortable exercising discretion and independent judgment in performing job duties, including evaluating options and determining actions within scope.

Responsibilities

• Define product requirements and features from customer needs and business priorities, explaining trade-offs among UX, performance, cost, reliability, and development time.
• Build prototypes for new product ideas, design pilots, and translate findings into requirements for larger pilots.
• Create CAD drawings and select materials and fabrication methods for development stages.
• Apply mechanical fundamentals, tolerance analysis, and targeted calculations or simulations to risks that matter; design and run physical tests to validate assumptions.
• Integrate mechanical designs with electronics, sensors, and firmware, and debug cross-interface issues with teammates.
• Lead mechanical engineering with manufacturing partners during NPI: investigate issues, assess changes, and define corrective actions.
• Collaborate with suppliers on prototype parts, feedback, build issues, and readiness for larger pilots; bring in specialists as needed.
