In addition, the candidate will interface with government personnel and program leadership on a regular basis. The candidate will be responsible for providing guidance, coaching, mentoring, and training to other employees across the business within the candidate’s areas of expertise.

This position is an onsite role, located in Tucson, AZ.

What You Will Do

• Specify, design, and test advanced RF sensors and subsystems across frequencies from MHz through millimeter-wave.

• Decompose system-level requirements into detailed RF component requirements.

• Measure RF components/sensors/subsystems, including performance in chamber and range environments.

• Perform modeling and analysis of link budgets, RF cascades, electromagnetic emissions (EME), antenna patterns, phase noise, receiver sensitivity, transmitter power, spurious signals, modulation, isolation, and ADC characteristics.  

Qualifications You Must Have

• Master of Science degree in Technology, Engineering, or Mathematics (STEM)

• A minimum of 10 years of prior relevant experience, or a PhD in a related field and minimum 7 years of experience to include any combination of the following:
