About You and the Role You are excited by the challenge of designing complex electromechanical systems from early concept to scaled production and real-world deployment.

You enjoy owning hardware deeply:

defining requirements, developing architectures, building and iterating prototypes, validating performance, and partnering across disciplines to bring robust designs into production. As a Senior Mechanical Engineer on the Long Range Platform, you will lead the design and development of hardware that must perform reliably in demanding field conditions. You will drive engineering decisions across the full product lifecycle, from first principles analysis and hands-on prototyping through validation, manufacturing ramp, and deployment. This role requires strong technical judgment, high ownership, and a willingness to move fluidly between detailed mechanical design work and broader system-level tradeoffs. You will work closely with Electrical, Software, Integration, Test, Manufacturing, Operations, and Supply Chain teams to deliver hardware that is not only functional, but manufacturable, inspectable, serviceable, and built to scale. What You'll Do Own critical mechanical systems and assemblies from concept through production and deployment Develop elegant, practical design solutions for highly integrated electromechanical hardware Translate product and system requirements into robust mechanical architectures, detailed designs, and validation plans Perform first-principles analysis, hand calculations, tolerance analysis, and FEA to inform design decisions Build prototypes, run experiments, and iterate quickly based on test data and field needs Partner with suppliers to improve manufacturability, quality, cost, and scalability Drive design reviews and cross-functional decision-making with Electrical, Software, Integration, Test, and Production teams Ensure designs meet requirements for safety, performance, reliability, manufacturability, and serviceability Support hardware through build, qualification, and production ramp, staying close to issues until they are fully resolved Contribute to a culture of high standards, fast learning, and mission-driven execution What You'll Bring Must Have Experience / Skill Sets 4+ years of full-time industry experience designing electromechanical and structural assemblies Proven ownership of complex subassemblies or full systems through multiple product development cycles Demonstrated CAD fluency for system-level ownership (3D/2D of 20-30 parts simultaneously) Experience working directly with suppliers and incorporating DFM feedback into design decisions Experience working on structural components and mechanisms, identifying worst-case loads, creating quick test setups Strong foundation in GD&T, FEA, design for assembly, and design for real-world field operation Hands-on prototyping experience and a track record of moving quickly through build-test-iterate cycles Ability to use hand calculations to bound problems and validate designs(beam, buckling, bolted joints, etc.) Knowledge of appropriate safety margins for human safety critical applications Experience with electromechanical assemblies including PCBAs, sensors, and connectors Excellent written, verbal, and visual communication skills Nice To Haves Aerospace or automotive validation experience Experience scaling hardware from prototype builds to production processes such as injection molding, stamping, extrusion, or other high-volume methods Experience with carbon fiber composite structures Explicit experience with high-efficiency electric powertrain components Experience working with highly integrated electromechanical assemblies with system-level constraints Ability to think beyond just mechanical engineering- proven track record of addressing the reliability, maintenance, systems, and safety aspects of a complex system NX as your primary CAD tool What Else You Need to Know The starting cash range for this role is $145,000 - $225,000. Please note that these are starting salary ranges that represent multiple internal levels. The final cash pay will depend on experience, qualifications, skills, location, and projected impact.
