Sr Mechanical Engineer, Fan and Duct Design

Figure AI Figure AI · Robotics · HQ · Hardware

Figure AI is an AI robotics company developing autonomous general-purpose humanoid robots. This role is for a Sr. Mechanical Engineer focused on Fan and Duct Design, responsible for the end-to-end development of the robot’s airflow systems, from initial design to production-ready assemblies. The role requires expertise in mechanical design for airflow systems, CAD modeling, DFM for injection molding, and collaboration with various engineering teams and suppliers.

What you'd actually do

  1. Own the mechanical design of the robot’s fan assemblies: impellers, housings, ducts, diffusers, seals, shrouds, baffles, and mounting structures.
  2. Translate CFD-engineered impeller geometry into fully detailed, moldable components with proper drafts, ribs, gates, cooling channels, and tooling strategies.
  3. Develop manufacturable plastic parts (injection-molded), metal components, and hybrid structures for quiet, efficient airflow.
  4. Select, qualify, and integrate fan motors including BLDC, slotless motors, PMSMs, or custom motor architectures depending on system targets.
  5. Collaborate with motor vendors and CMs to determine winding specs, bearings, back-EMF constants, and long-life design constraints with additional support from the Figure motor team
