Principal Mechanical Engineer

Requirements

• A bachelor's or master's degree in Mechanical Engineering or a related field.
• A Mechanical Engineer with 10+ years of experience, ideally in robotics, automation, consumer electronics, aerospace, or EV, with a strong structural design background and a track record of technical ownership at the system level.
• FEA experience that goes beyond the resume line. Has worked through real structural problems. The candidate should be able to set up their own analyses, sanity-check results with hand calculations, and close the loop with physical test data rather than trusting the model.
• Must have experience designing machined, sheet metal, and welded parts in OnShape and submitting documentation through ECO's and deviations in Arena or other similar tools.
• Comfortable ordering and building prototypes by hand to validate their ideas through prototyping and testing.
• Must have performed tolerance stackups, reviewed FAI's, PPAP's, and worked on DFMEA's throughout their career.
• Has followed designs through the production line, diagnosing and fixing issues in engineering or production builds, as well as in the field.
• Strong engineering judgment across both design and hands-on execution, with the ability to move between CAD, simulation, building, testing, and debugging real hardware.
• Adept at communicating complex concepts and writing technical documents.
• Experience evaluating design, performance, and logistical tradeoffs for hardware systems.
• Experienced in designing for a range of manufacturing processes, including CNC machining, sheet metal fabrication, welding, and 3D printing.
• Able to work in a fast-paced, collaborative environment
• Comfortable thinking at the product level, seeing how mechanical subsystems connect, package, and are manufactured together, and can make system-level architecture calls that hold up through production and deployment, not just through the design review.
• Experience mentoring or technically guiding junior and mid-level engineers on design reviews, DFM, and best practices.
• Willing and able to work from our Charlestown, MA office at least 4 days per week.
