Job summary

Shield AI is expanding its Avionics Engineering team to advance a flight-critical, custom avionics system for the X-BAT aircraft. The early-career Test Engineer will set up dynamometer and battery energy storage tests, configure instrumentation, and collaborate across electrical, mechanical, and test engineering groups.

The role focuses on testing, debugging, and data-driven evaluation of energy storage, electric machines, and motor-drive systems in a lab environment in Seattle, WA.

Qualifications

• Associate degree or higher in electrical technology, mechanical technology, mechatronics engineering, electrical engineering, mechanical engineering or a related technical discipline.
• Hands-on experience with batteries, dynamometers, electric motors, motor drives, powertrain systems, or comparable electromechanical equipment through employment, internships, academic teams, clubs or personal projects.
• Experience setting up and executing hardware tests using instrumentation, sensors and data-acquisition equipment.
• Experience troubleshooting systems involving electrical and mechanical components.
• Familiarity with benchtop electrical equipment such as multimeters, oscilloscopes, power supplies and electronic loads.
• Ability to read and interpret electrical schematics, wiring diagrams, mechanical drawings and test procedures.
• Understanding of laboratory safety practices, including the safe operation of high-voltage or high-power equipment.
• Demonstrated ownership, reliable execution, clear documentation, and effective collaboration with engineers, technicians and cross-functional partners.

Responsibilities

• Set up and operated dynamometer systems for electric motor and motor-drive testing.
• Setup and operate battery energy storage systems for testing.
• Configure instrumentation, sensors, fixtures, harnesses and data-acquisition equipment.
• Execute test campaigns for electromechanical or electrochemical subsystems, verifying voltage rails, logic levels, performance, thermal behavior and overall functionality.
• Perform testing, debugging and system-level troubleshooting.
• Collect and evaluate test data, identify abnormal behavior and communicate findings.
• Support environmental qualification testing, including temperature, vibration, altitude and humidity.
• Install, verify, and deploy DC-sources, power converters, test fixtures and harnesses.
