Sr. Mechanical Engineer, Terafab

What You'll Do

• Own mechanical design across the fab – custom tooling, material handling systems, equipment supports, process machinery, and manufacturing systems
• Work from first principles – evaluate trade-offs (why 5-point vs 3-point support?), select materials against thermal, mechanical, and cost constraints, and defend the design with physics rather than heuristics
• Act as the interdisciplinary system owner – integrate mechanical, thermal, electrical, and process requirements, and balance competing constraints across domains
• Lead hardware end-to-end – from concept through production ramp, including qualification, documentation, and handoff to operations
• Simplify through design – eliminate parts, reduce assembly steps, and design for the build sequence and for serviceability
• Work hands-on on the fab floor – commission systems, measure reality against CAD, and debug the multi-variable failures that only surface at scale (tolerance stack-ups, thermal growth, dynamic loads)

What You'll Bring

• Degree in Mechanical Engineering, or equivalent experience
• 5+ years of mechanical design experience in high-volume manufacturing – full lifecycle from concept through production and continuous improvement
• Exceptional first-principles ability – derive solutions from statics, dynamics, heat transfer, and materials science
• Cross-disciplinary fluency – work across mechanical, thermal, electrical, and process domains to drive system-level decisions
• Expert CAD (CATIA, SolidWorks, or similar) with fluency in GD&T, tolerance analysis, DFM/DFA, and FEA/CFD for design validation
• Deep knowledge of machines and manufacturing – motors, bearings, actuators, sensors, robotics, and how parts are made at scale (machining, sheet metal, casting, welding)
• Proven commissioning and troubleshooting experience – hands-on assembly, debug, and ramp of physical systems; bridges the gap between "works in CAD" and "works in production"
