Job Description:
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.
What you'll do:
- 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
Required qualifications:
- 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
