Mechanical Engineer, Dynamometer and Actuator Testing Infrastructure

Design, build, and own the mechanical side of robotic actuator dynamometer and test infrastructure Create test stands, couplings, fixtures, load paths, guarding, and serviceable lab hardware Take actuator test infrastructure from requirements and analysis through CAD, fabrication, assembly, commissioning, and iteration Own the mechanical architecture of dynamometer and actuator test cells, including frames, bases, load paths, alignment, guarding, and serviceability Design dynamometer structures, robotic actuator fixtures, load-motor mounts, couplings, shafts, bearings, adapters, and torque-reaction hardware Translate actuator test requirements into systems for torque, speed, thermal, durability, backdrive, efficiency, and failure testing Perform first-principles analysis and simulation for stiffness, strength, fatigue, vibration, thermal growth, critical speed, and safety factors Create precise, repeatable alignment strategies Design modular fixturing for rapid changeover across actuator and motor variants Partner with electrical engineers on cable routing, enclosures, cooling, sensor packaging, and test-cell safety interfaces Partner with software and controls engineers to define mechanical limits, safe operating envelopes, and automated-test constraints Build, assemble, debug, and improve test stands in the lab Develop guarding, containment, pinch-point mitigation, hard stops, and other mechanical safety systems Manage fabrication partners and vendors Establish drawings, tolerance stacks, assembly procedures, inspection plans, and preventive-maintenance practices Use test observations and failure analysis to improve durability, usability, uptime, and measurement fidelity
