Lead Electrical Engineer, Robotic Actuator Test Cells

United States Digital Space LLC; United States; Remote; USD 120,000 - 180,000; Full time

Job summary

United States Digital Space LLC is seeking an Electrical Engineer to build and own the electrical backbone of robotic actuator testing. You will design, integrate, and operate load motor drives, power distribution, instrumentation wiring, DAQ interfaces, and safety systems for repeatable, safe, scalable testing.

The role spans hands-on lab work and system architecture: selecting power electronics, designing robust test cells, bringing up sensors, and collaborating with mechanical and software

Qualifications

• Bachelor’s or graduate degree in Electrical Engineering, Robotics, Mechatronics, or 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 clear electrical documentation.
• Experience troubleshooting complex electromechanical systems with oscilloscopes, meters, power analyzers, and other lab tools.

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 from robotic actuators 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, rapidly 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 engineers on packaging, cooling, fixturing interfaces, and serviceability of test infrastructure.
• Partner with software and controls engineers on I/O maps, real-time signals, calibration, automated sequences, and reliable data capture.
• Establish commissioning, calibration, inspection, and preventive-maintenance procedures for lab electrical systems.
• 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 that enable a growing dyno lab to operate safely and consistently.
