(Volunteer) Test Engineer – Prosthetic Devices

Universal Limbs is a nonprofit developing accessible upper-limb prosthetic solutions. The Test Engineer will strengthen the prosthetic arm MVP test plan and support development of physical test benches for a body-powered, 3D-printed transradial prosthetic hand.

Responsibilities

• Review and validate mechanical verification/test plans and identify gaps in methods, loads, acceptance criteria, and evidence
• Design and build test benches, fixtures, and jigs for functional, force, durability, cyclic, and environmental testing
• Translate design requirements into traceable and repeatable verification procedures
• Define instrumentation, loading conditions, measurements, data collection, and acceptance criteria
• Support testing of pinch force, object retention, actuation/release, structural durability, cyclic wear, attachments, and silicone-glove performance
• Analyze test results, failure modes, and experimental uncertainty
• Ensure test methods and documentation align with applicable ISO and/or recognized regulatory/industry standards

Preferred

• Upper-limb prosthetics, orthotics, rehabilitation, or assistive-device testing experience
