Senior Mechanical Engineer

Job description

Job responsibilities

• Design parts and assemblies in 3D CAD that satisfy load conditions, form factor constraints, range-of-motion requirements, and durability targets
• Determine component-level mechanical requirements (stiffness, strength, fatigue, thermal) from system-level functional specs
• Apply analytical methods — FEA, tolerance stack-up, kinematic analysis — before releasing designs for prototyping or production
• Generate accurate 2D drawings with GD&T per ASME Y14.5 appropriate for both prototype and production inspection methods
• Build prototypes to test assembly, range of motion, wire routing, and integration with adjacent subsystems
• Design and build test stands and fixtures; conduct structured validation testing and document results rigorously
• Own the prototype-to-production transition for your subsystems: apply DFM/DFA principles from the first design iteration, not as a final step;
• Work with suppliers to select and qualify parts; inspect first articles, perform root cause analysis on failures, and drive corrective action through to closure

Job requirements

• 5+ years of mechanical engineering experience in robotics, industrial automation, automotive, aerospace, or consumer electronics — with at least one product shipped to production
• Expert proficiency in 3D CAD (SolidWorks, NX, CATIA, Onshape, or equivalent) for complex parts and assemblies with tight tolerances
• Mastery of GD&T per ASME Y14.5 and the ability to create production-ready 2D drawings
• Experience with actuators and transmission systems: strain-wave (harmonic), planetary, cycloidal gearing, or direct-drive
• Hands-on experience with structural analysis (FEA) and tolerance stack-up analysis as part of routine design validation
• Proven electromechanical integration experience: motors, sensors, encoders, wire harnesses, and connectors in tight mechanical envelopes
• Demonstrated ability to take a mechanical design from working prototype to production-ready — including DFM iterations, supplier qualification, first-article inspection, and manufacturing yield validation;
• Deep familiarity with modern manufacturing processes and when to apply each: CNC machining (3- and 5-axis), injection molding, die casting, sheet metal fabrication, MIM (metal injection molding), investment casting,…
