  • Experienced with hardware lab equipment for test, measurement (e.g. oscilloscope, power supply, DMM, etc.), and/or prototyping (Raspberry Pi, Arduino, 3D printing, powertools, etc.)
  • Enthusiastic to apply engineering problem-solving skills to dig into challenges that are outside of your expertise.
  • Collaborative: have the ability to work as a team, ask questions, and share information to solve problems.
  • Flexible: have the desire to help partner teams when boundaries may be ambiguous
  • Able to articulate technical information to audiences that include members of various levels of technical expertise.
