## Job Description

## Responsibilities
- Own the electrical architecture of dynamometer and actuator test cells, from mains distribution and protection through load motor drives, braking, and auxiliary power.
- Specify, integrate, commission, and tune motor drives and load machines for robotic actuator torque, speed, efficiency, thermal, and durability testing.
- Design power distribution, grounding, shielding, cable routing, and connectorization for high-current, high-voltage, and low-level measurement systems.
- Integrate torque, position, speed, temperature, voltage, current, vibration, and other instrumentation into DAQ and control systems.
- Develop electrical schematics, wiring diagrams, panel layouts, harness documentation, and test-cell interface definitions.
- Build, debug, and maintain test-cell electrical hardware, diagnosing noise, EMI, grounding, drive, sensor, and power-quality issues.
- Design and validate safety circuits, including E-stops, interlocks, contactors, safe torque off, guarding interfaces, and fault detection.
- Partner with mechanical, software, and controls engineers on packaging, cooling, I/O maps, calibration, automated sequences, and reliable data capture.
- Establish commissioning, calibration, inspection, and preventive-maintenance procedures.
- Evaluate vendors and components for drives, motors, sensors, DAQ hardware, protection devices, and electrical enclosures.
- Analyze test and diagnostic data to improve measurement quality, cell uptime, and hardware reliability.
- Set practical electrical standards for safe and consistent dyno-lab operation.

## Requirements and Preferred Qualifications
- Bachelor’s or graduate degree in Electrical Engineering, Robotics, Mechatronics, or a related field.
- Experience building, commissioning, or maintaining electrical systems for robotic actuator dynamometers, robotics, automation, motors, power electronics, or industrial test equipment.
- Hands-on experience with motor drives, servo systems, load motors, power distribution, and electrical protection.
- Strong understanding of grounding, shielding, EMI/EMC, signal integrity, and instrumentation wiring.
- Experience integrating sensors and DAQ hardware for voltage, current, torque, position, speed, temperature, or vibration measurements.
- Familiarity with electrical safety practices, E-stops, interlocks, safe torque off, lockout/tagout, and relevant lab or machinery standards.
- Ability to create and maintain schematics, wiring diagrams, panel layouts, and electrical documentation.
- Experience troubleshooting complex electromechanical systems with oscilloscopes, meters, power analyzers, and other lab tools.
- Strong communication and cross-functional collaboration skills.
- Willingness to work hands-on in a lab and take ownership of safety and operational reliability.

## Compensation
- Salary range: $225,000–$295,000 USD.
