Senior Mechanical Engineer - Robotics, Production Ready

Roboticsconnected; Fremont (CA); On-site; USD 130,000 - 180,000; Full time

Job summary

Dexmate is seeking a Senior Mechanical Engineer to design, test, and implement key hardware components for our humanoid robot platform. You will own mechanical subsystems end-to-end—from requirements through 3D CAD, prototyping, supplier qualification, and production release.

This hands-on role spans from bench prototypes to volume production, emphasizing manufacturability, DFM reviews, first-article inspection, and tight integration with electrical, firmware, and controls teams to ship reliable

Qualifications

• 5+ years of mechanical engineering in robotics or similar fields with at least one production ship
• Expert in 3D CAD (SolidWorks, NX, CATIA, Onshape or equivalent) for complex parts
• Mastery of GD&T per ASME Y14.5 and production-ready drawings
• Experience with actuators and transmission systems: harmonic, planetary, cycloidal gearing, or direct-drive
• Hands-on structural analysis (FEA) and tolerance stack-up analysis for design validation
• Proven electromechanical integration experience: motors, sensors, encoders, harnesses, and connectors in tight envelopes
• Proven ability to take a mechanical design from working prototype to production-ready — including DFM iterations, supplier qualification, first-article inspection, and manufacturing yield validation

Responsibilities

• Design parts and assemblies in 3D CAD that satisfy load conditions, form factor constraints, ROM, and durability targets
• Determine component-level mechanical requirements from system specs
• Apply analytical methods — FEA, tolerance stack-up, kinematic analysis — before prototyping or production
• Generate 2D drawings with GD&T per ASME Y14.5 for prototype and production
• Build prototypes to test assembly, range of motion, wire routing, and integration with subsystems
• Design and build test stands and fixtures; conduct structured validation testing and document results
• Own the prototype-to-production transition for subsystems: apply DFM/DFA principles from first iteration
• Collaborate with suppliers to select and qualify parts; inspect first articles and drive corrective action to closure
• Conduct DFM/DFA reviews with contract manufacturers; define mechanical acceptance criteria and support tooling
• Define and execute validation plans — environmental, fatigue, functional testing
• Collaborate with electrical engineers on electromechanical integration
