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.

  • 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
