Battery Test Engineer II (Avionics)

About the role

Shield AI is growing its Avionics Engineering team to support the development of the X-BAT aircraft, a flight-critical custom avionics system covering communications, compute, AI, power, telemetry and other aircraft systems. It is looking for an early-career Test Engineer to set up, operate and analyze battery storage test systems that characterize energy storage. The role sits at the intersection of electrical, mechanical, chemical and test engineering, working closely with the Power Systems team and other engineering groups through design, verification, integration and qualification. The position is based in Seattle, WA or San Diego, CA.

Key responsibilities

• Set up and operate battery energy storage systems for testing
• Configure thermal chambers, battery cyclers, instrumentation, sensors, fixtures, harnesses and data-acquisition equipment
• Run test campaigns for electrochemical subsystems, checking 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 report 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
• Help design and build out the battery test labs

Required profile

• Bachelor's degree or higher in chemical, electrical or mechanical engineering or a related technical discipline
• Hands-on experience with batteries, powertrain systems or comparable electrochemical equipment through work, internships, academic teams, clubs or personal projects
• Experience setting up and running hardware tests with instrumentation, sensors and data-acquisition equipment
• Experience troubleshooting systems with electrical and mechanical components
• Understanding of laboratory safety practices, including high-voltage or high-power equipment
• Demonstrated ownership, reliable execution, clear documentation and effective collaboration with engineers, technicians and cross-functional partners

Required skills

• 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
