Skills & highlights for this role

  • injection molding DFM
  • GD&T and tolerance stack-up
  • polymer materials selection
  • Class-A surfacing

Also useful

  • SolidWorks
  • CATIA
  • mold flow analysis
  • ASME Y14.5

Responsibilities

  • Own the mechanical design of A-surface plastic components for the robot - covers, skins, shrouds, bezels, and cosmetic enclosures - from industrial design intent through production tooling.
  • Develop Class-A surfaces and translate ID surfacing into manufacturable parts, holding gap-and-flush, parting line, draft, and aesthetic intent across the full assembly.
  • Select polymers and processes across the cosmetic stack: ABS, PC, PC/ABS, PA and glass-filled grades, TPU/TPE, and specialty resins - balancing appearance, impact and creep behavior, chemical and UV resistance, flammability, and cost.
  • Define and own GD&T, tolerance stack-ups, and datum schemes across multi-part plastic assemblies and their interfaces to structures, actuators, and electronics.
  • Drive DFM and DFA for injection molding, insert molding, overmolding, and secondary operations - gate and ejector strategy, wall thickness, ribbing and boss design, warp and sink mitigation, and shutoff design.
  • Own cosmetic specification: textures, gloss levels, color matching, painting, plating, laser etching, and in-mold decoration, plus the defect standards and limit samples that go with them.
  • Work directly with tool shops, molders, and CMs through tool kickoff, T0/T1 sampling, tuning, and PPAP - reviewing mold flow, tool design, and first-shot parts, and driving corrective action.
  • Build and test prototypes using 3D printing, urethane casting, CNC, and soft tooling, then validate with drop, structural, and environmental testing.

Qualifications

  • Exceptional mechanical intuition. You understand how polymers flow, shrink, warp, and fail - and you can predict it before the tool is cut.
  • 5+ years designing injection-molded plastic parts for high-volume consumer, automotive, or robotics products, with parts you took from CAD through production tooling.
  • Deep, hands-on knowledge of polymer materials science: resin families, fillers and additives, anisotropy, moisture sensitivity, and how process conditions change part behavior.
  • Fluent in GD&T (ASME Y14.5 or ISO GPS) and tolerance analysis, including worst-case and statistical stack-ups on compliant plastic parts.
  • Proven experience owning cosmetic A-surface parts and defending appearance standards with vendors.
  • Strong surfacing skills in SolidWorks, CATIA, NX, Creo, or similar; comfort reading mold flow results and tool drawings.
  • Comfortable with ambiguity, moves fast, and curious about how the whole system works.
