Tooling & Fixturing Engineer

Design and own production tooling and fixtures (weld fixtures, assembly jigs, lifting tools) from concept through validation, lifecycle management, and operator-focused design for high-volume fabrication/assembly. Requires proven experience designing fixtures that hold tolerance at rate using proper stack-ups and capability studies.

About the job

Role Scope

  • Design the tooling and fixtures the factory builds with: weld fixtures, assembly jigs, and lifting and handling tools.
  • Own fixtures from concept through proving: tolerance stack-ups, repeatability studies, and sign-off.
  • Manage the tooling lifecycle: maintenance, calibration, revisions, and the register that tracks it all.
  • Design for the operator: fast loading, mistake-proofing, and safe handling of heavy parts.

What We're Looking For

  • You've designed production tooling and fixtures for fabrication or assembly, and they're still in use.
  • You do stack-ups properly and your fixtures hold tolerance at rate.
  • You've proven fixtures with capability studies, not eyeballs.
  • You design mistake-proofing in rather than inspecting errors out.
  • You revise fast when the product changes.

Bonus: Weld fixture design. GD&T depth. SolidWorks or Inventor. Lifting device design standards.
