Senior Mechanical Engineer

• Own the mechanical design and architecture of robotic subsystems — structures, mechanisms, frames, housings, and precision assemblies — from concept through production deployment
• Produce production-grade engineering drawings with GD&T (ASME Y14.5): sound datum schemes, functional tolerancing, and tolerance stack-up analysis that suppliers can build from without guessing
• Develop detailed 3D CAD models and assemblies, and drive system-level mechanical design decisions
• Perform engineering calculations, hand calcs, structural/stress analysis, and FEA to ensure performance, reliability, and manufacturability.
• Design for manufacturability (DFM), assembly (DFA), reliability, serviceability, and cost
• Select and integrate mechanical and electromechanical components — bearings, gears, transmissions, and fasteners, along with the motors, gearboxes, and sensors your designs interface with
• Partner with controls, software, electrical, embedded, perception, and manufacturing teams to deliver integrated robotic systems
• Lead prototype builds, debugging, root-cause investigations, and field performance improvements
• Establish and execute validation plans, reliability testing, and qualification procedures
• Support the supply chain across the product lifecycle — support sourcing and supplier selection, drive supplier development and second-sourcing, and resolve component and manufacturability issues fast to keep builds on schedule
• Own part quality for the components you design — define inspection and measurement requirements on your drawings, lead first-article inspection, and drive root-cause and corrective action on nonconformances alongside suppliers and the quality team
• Drive cost reduction across new and existing parts — through tolerancing, material, and process choices, value engineering (VA/VE), and design-to-cost — to hit unit-cost targets as we scale
• Support the transition from prototype to production, including documentation, manufacturing support, and quality improvements
• Mentor engineers and contribute to mechanical engineering best practices, drawing standards, and design reviews

• Bachelor's degree in Mechanical Engineering or a related field
• 7+ years developing complex mechanical or electromechanical hardware
• Deep mechanical engineering expertise: machine design, mechanisms, structural and stress analysis, solid mechanics, materials, and product development
• Strong, demonstrable GD&T fluency (ASME Y14.5) — you can define a datum scheme, defend a tolerance stack, and produce release-ready drawings
• Proficiency with 3D CAD tools such as SolidWorks, Creo, or equivalent
• Solid understanding of manufacturing processes — machining, sheet metal, injection molding, weldments, and assembly methods — and how design choices drive cost and yield
• Track record of driving part quality and cost reduction with suppliers — first-article inspection, supplier development, root-cause/corrective action, and tolerance, material, and process trade-offs made with cost and quality in mind
• Comfortable interfacing with electrical, controls, and embedded systems: you design mechanical systems that integrate cleanly with motors, sensors, and electronics, without needing to own circuit design or control loops
• Experience with prototyping, testing, troubleshooting, and system integration
• Ability to interpret test data and drive engineering decisions through quantitative analysis
• Strong communication skills and the ability to work effectively across multidisciplinary teams

• Master's degree in Mechanical Engineering or a related discipline
• Experience with industrial robotics, warehouse automation, or autonomous systems
• Experience with FEA, dynamic simulations, and tolerance stack-up analysis
• Familiarity with model-based definition (MBD)
• Experience scaling products from prototype to high-volume manufacturing
• Experience with value analysis / value engineering (VA/VE), design-to-cost, or supplier-quality programs
• Familiarity with reliability engineering and field-deployed hardware
• Experience leading technical projects and mentoring engineers
