Date Posted: 2026-06-15

Country: United States of America

Location: US-AZ-TUCSON-M02 ~ 1151 E Hermans Rd ~ BLDG M02

Position Role Type: Onsite

At Raytheon, the foundation of everything we do is rooted in our values and a higher calling – to help our nation and allies defend freedoms and deter aggression. Our team solves tough, meaningful problems that create a safer, more secure world.

What You Will Do

• Design, test, and integrate RF sensors and subsystems across frequencies from MHz through millimeter-wave.
• Support the decomposition of 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

• Bachelor of Science degree in Technology, Engineering, or Mathematics (STEM)
• A minimum of 5 years of prior relevant experience, or an advanced degree in a related field and minimum 3 years of experience to include any combination of the following:
• Design, integration, and/or test of RF subsystems
• Design, integration, and/or test of RF sensors
• Experience interacting across engineering disciplines (e.g. Systems, Mechanical, SW, Algorithms, etc.) to define RF subsystem requirements and evaluate performance
• Ability to obtain INTERIM U.S. government‑issued security clearance prior to start date with the ability to obtain special program access after start.

Qualifications We Prefer

• Knowledge of RF component technologies, including circuit card assemblies (CCAs), waveguides, planar/printed antennas, RF modules, and/or monolithic microwave integrated circuits (MMICs).
• Experience performing link budget analyses.
• Understanding of antenna patterns and RF measurements with antennas and electronics.
• Experience in concepts such as phase noise, mixer conversion spurs, automatic gain control (AGC), sensitivity, intermodulation distortion (IMD), bit error rate, instantaneous bandwidth, adjacent channel interference, and ADC measurements/calculations (Nyquist and SFDR).
• Familiarity with equipment such as spectrum analyzers, network analyzers, signal generators, and arbitrary waveform generators (ARB generators).
• Understanding of electromagnetic interference (EMI) and electromagnetic vulnerability (EMV) along with mitigation strategies in RF systems.
• Excellent written communication and oral presentation skills.

What We Offer

This position offers relocation based on candidate eligibility.
