Engineer II, Battery Test (R5954)

We are growing the Avionics Engineering team to support the development of the X-BAT aircraft. Our team is designing a flight-critical, custom avionics system supporting communications, compute, AI, power, telemetry and other essential aircraft systems.

Shield AI is seeking an early-career Test Engineer to support the testing and verification of X-BAT’s battery energy storage. This position will be primarily responsible for setting up, operating, and analyzing battery storage based test systems used to characterize energy storage.

The role sits at the intersection of electrical, mechanical, chemical and test engineering.  You will partner closely with the Power Systems team and other cross-functional engineering groups throughout design, verification, integration and qualification.

This position is based in Seattle, WA, or San Diego, CA.

Setup and operate battery energy storage systems for testing

Configure thermal chambers, battery cyclers, instrumentation, sensors, fixtures, harnesses and data-acquisition equipment

Execute test campaigns for 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 external test lab qualification testing, including failure modes, temperature, vibration, humidity and altitude 

Install, verify, and deploy DC-sources, power converters, test fixtures and harnesses

Assist with the design and buildout of the battery  test labs

Bachelor's degree or higher in chemical engineering, electrical engineering, mechanical engineering or a related technical discipline

Hands-on experience with batteries, powertrain systems, or comparable electrochemical 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
