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. We bring the strength of more than 100 years of experience and renowned engineering expertise to meet the needs of today's mission and stay ahead of tomorrow's threat. Our team solves tough, meaningful problems that create a safer, more secure world.

The Effector RF Team at Raytheon is seeking a talented Principal Engineer to join our team in Tucson, AZ.

The candidate will be responsible for contributing to the architecture, analysis, design, and implementation of RF subsystems and sensors within missile products. The selected candidate will be expected to provide technical expertise, lead small teams, and work with the Engineering organization to establish technology roadmaps, enable modernization, and contribute to general innovation. In addition, the candidate will interface with government personnel and program leadership on a regular basis. The candidate will be responsible for providing expertise, leadership, and subject matter support to RF projects and team members.

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

• Bachelor of Science degree in Technology, Engineering, or Mathematics (STEM)
• A minimum of 8 years of prior relevant 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

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.
