Senior Mechanical Engineer
$150,000–$150,000 year
On-siteSan Francisco, California, United States
Job Summary
Own mechanical design and architecture for robotic subsystems, including structures, mechanisms, and precision assemblies, from concept through production deployment. Produce production-grade engineering drawings with GD&T (ASME Y14.5), perform structural analysis and FEA, and drive design for manufacturability, assembly, and cost reduction. Select and integrate electromechanical components, partner with cross-functional teams to deliver integrated systems, and lead prototype builds and root-cause investigations. Support the supply chain by driving supplier development, resolving manufacturability issues, and defining inspection requirements to ensure part quality. Mentor engineers and contribute to mechanical best practices while accelerating product development and supporting the transition from prototype to high-volume manufacturing.
Required Qualifications
- 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
Desired Qualifications
- 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
