We pride ourselves on a culture of ambition, creativity, and teamwork, constantly seeking innovative minds ready to challenge norms and drive progress in our field.

About the Role

Whisper is seeking a mid-career or senior ground test engineer to assist in the research and development of Whisper’s revolutionary electric propulsors. This candidate will create ground test rigs, design experiments for static tests and wind tunnel tests, define and implement instrumentation to collect key data, define and write data acquisition software, and collect and process test data. The candidate should have both a strong background in instrumentation and associated electronics and software as well as some background in propulsion aerodynamics.

What You’ll Do

  • Use first principles to determine the validity of an idea (for example: back-of-the-envelope hand calcs or a basic physics model)
  • Design test equipment, load measurement rigs, electronics, general data acquisition hardware systems, aerodynamics measurement rigs, etc.
  • Select and implement instrumentation to measure various test article performance
  • From limited information create and implement test plans, design efficient experiments, collect data, post-process test data and report findings to team
  • Troubleshoot electronic and instrumentation systems
  • Communicate with other groups to integrate designs and frameworks
  • Lead design reviews
