About the role

Test Fixture Design Engineer role within the Test & Validation team focused on designing and delivering mechanical test fixtures for NEO humanoid robot validation, from concept through production handoff and in-lab implementation.

Responsibilities

  • Design and deliver the mechanical test fixtures that enable safe, accurate, and repeatable validation of NEO and its critical subsystems.
  • Own fixture development end-to-end, from understanding the test objective and developing the initial concept through CAD, drawings, fabrication, assembly, test-cell installation, and iteration based on real-world test results.
  • Develop fixture designs that are robust, easy to manufacture, and minimize unnecessary complexity, cost, and test-induced artifacts.
  • Produce production-ready fixture design packages including 3D CAD, 2D drawings, materials, tolerances, hardware, interfaces, and assembly requirements.
  • Drive successful manufacturing handoff by working with internal fabrication teams and external vendors to resolve DFM issues, manage quotes and lead times, and deliver hardware to test schedules.
  • Bring fixtures from CAD into the lab through hands-on assembly, fit checks, installation, and test setup, iterating designs based on test-cell feedback.

Qualifications

  • Bachelor’s degree in Mechanical Engineering or closely related engineering discipline.
  • 2-4 years of experience designing mechanical test fixtures, assembly fixtures, tooling, or similar custom hardware.
  • Strong 3D CAD and 2D engineering drawing skills, with experience designing parts and assemblies for machining, fabrication, or rapid prototyping.
  • Experience working with internal machine shops or external manufacturing vendors to turn designs into physical hardware.
  • Practical understanding of mechanical testing, including loads, load paths, fixturing, interfaces, and safe test setup.
