Responsibilities

Own the mechanical design of the robot’s fan assemblies: impellers, housings, ducts, diffusers, seals, shrouds, baffles, and mounting structures

Translate CFD-engineered impeller geometry into fully detailed, moldable components with proper drafts, ribs, gates, cooling channels, and tooling strategies

Develop manufacturable plastic parts (injection-molded), metal components, and hybrid structures for quiet, efficient airflow

Select, qualify, and integrate fan motors including BLDC, slotless motors, PMSMs, or custom motor architectures depending on system targets

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

Support thermal and acoustic engineers by designing test fixtures, running airflow tests, and validating fan performance

Own iterative cycles: prototype → measure → redesign → retest

Drive supplier engagement on tooling, gating, draft strategies, warpage control, and tolerance analyses

Partner with GSM and CMs to close out DFM, tooling release, mold trials, and FAIs

Create drawing packages, GD&T, BOMs, and assembly instructions for production

Collaborate with CFD, thermal, acoustics, system architecture, IDand manufacturing teams to converge on a highly optimized fan system

Work with global suppliers to evaluate materials, molding processes, motor options, and assembly methods

Provide hands-on build support for engineering units and early factory runs
