About the role

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 headquartered in San Jose, CA.

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.

The work

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.

Who they want

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.

Nice to have

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 $160,000 to $250,000 per year.

The pay offered for this position may vary based on several individual factors, including job-related knowledge, skills, and experience.
