Senior Gear Design Engineer

Figure is an AI robotics company developing autonomous general-purpose humanoid robots. The goal of the company is to ship humanoid robots with human level intelligence. Its robots are engineered to perform a variety of tasks in the home and commercial markets. Figure is based in San Jose, CA and requires 5 days/week in-office collaboration. We are looking for a Senior Gear Design Engineer to own gear and transmission design for our humanoid robot's hands — some of the most power-dense, space-constrained actuators in the world. You will take gear trains from first-principles sizing through validation and into mass manufacturing, defining how our robot grasps and manipulates the world. Responsibilities: - Own gear design end-to-end: system-level sizing, macro and micro geometry definition, rating and life analysis, prototyping, validation, and ramp to mass production. - Perform gear sizing, contact/bending stress analysis, and micro-geometry optimization (profile and lead modifications) in KISSsoft to meet efficiency, durability, backlash, and NVH targets. - Design gears, shafts, and transmission assemblies in 3D CAD (CATIA) that satisfy extreme packaging, load, and durability requirements of a high-DOF robotic hand. - Define gear manufacturing strategy — cutting, grinding, powder metal, MIM, or plastics — and drive DFM with suppliers from first articles through high-volume production. - Generate accurate 2D drawings with gear data tables and GD&T per ASME Y14.5, and define inspection and metrology plans for incoming quality. - Build and run test rigs to characterize efficiency, backlash, wear, and fatigue life; correlate test data back to analytical models. - Collaborate closely with actuator, structures, EE, and manufacturing teams — proactively identifying risks, driving decisions, and unblocking the program without waiting to be asked. Requirements: - 7+ years of experience designing gears and geared transmissions - Bachelor's or Master's Degree in Mechanical Engineering, Robotics, Mechatronics, or similar field - Demonstrated ownership of complete gear designs from initial sizing through mass manufacturing - Proficiency in KISSsoft (or equivalent) for gear rating, contact analysis, and micro-geometry optimization - Proficiency in CATIA (or equivalent high-end 3D CAD) for complex geometry and large assemblies - Working knowledge of AGMA/ISO gear rating standards, gear metrology, and tolerancing - Experience with gear manufacturing processes (hobbing, shaping, skiving, grinding, powder metal, MIM, or injection molding) and supplier development - A strong team player with a high sense of agency — you take ownership of outcomes, communicate openly, and elevate the people around you Bonus Qualifications: - Experience with small-module, high-ratio, or high-power-density gearing (planetary, cycloidal, or strain wave) - Experience in robotics, surgical devices, aerospace actuation, or automotive e-drive transmissions - Familiarity with lubrication selection, grease DOE, and tribology for compact gearboxes - Experience with fatigue modeling, bearing life characterization, and accelerated life testing - Experience taking a product through NPI builds (EVT/DVT/PVT) and FATP at volume The US base salary range for this full-time position is between $160,000 - $250,000 annually. The pay offered for this position may vary based on several individual factors, including job-related knowledge, skills, and experience. The total compensation package may also include additional components/benefits depending on the specific role. This information will be shared if an employment offer is extended.
