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.

Join our RF/Microwave Engineering team at Raytheon and help develop mission-critical technologies that protect the U.S. and our international allies. In this role, you will design, develop, integrate, test, and/or support the manufacture of advanced RF and microwave hardware for radar and sensing applications.

You may work across a broad range of technologies, including RF circuit card assemblies (CCAs) and modules for receivers, exciters, and transmitters; antennas and radomes; semiconductor devices; microwave and millimeter-wave integrated circuits (MMICs); and phased-array hardware.

You will collaborate closely with multidisciplinary engineering, manufacturing, test, and program teams throughout the full hardware development lifecycle-from concept development and detailed design through integration, verification, and transition to production. This is an opportunity to solve challenging RF problems, work hands-on with advanced hardware, and contribute directly to some of Raytheon's premier radar and sensing programs.

What You Will Do:

• Design, simulate, and analyze RF/microwave components, MMICs, CCAs, and/or phased array module hardware.
• Perform assembly, testing and characterization, of RF, microwave, and millimeter-wave hardware and/or devices.
• Execute component-level and system-level integration and testing for digital, analog, and RF assemblies.
• Utilize automated test instrumentation and software (e.g., Python, MATLAB, LabVIEW) to control measurement systems, capture data, and evaluate test results.
• Characterize and test hardware using advanced laboratory equipment, including Vector Network Analyzers (VNAs), Signal Generators, Spectrum Analyzers, Phase Noise Analyzers, and Performance Network Analyzers (PNAs).
• Conduct circuit simulations, obsolescence trade assessments, hardware troubleshooting, and failure investigations to resolve performance issues.
• Partner with multi-discipline teams.
• Participate in project design reviews, peer reviews, and briefings to internal program leadership and external customers.

What You Will Learn:

• RF simulation and design processes
• RF hardware characterization techniques, including using spectrum analyzers, network analyzers, signal generators, phase noise analyzers, etc.
• Software such as Keysight ADS, HFSS, Cadence Virtuoso, MATLAB, CST, Mentor Graphics' Expedition, Python, Labview

Qualifications You Must Have:

• Master's degree in Electrical Engineering, Applied Physics, or related Science, Technology, Engineering, or Mathematics (STEM) discipline. Degree must be obtained by start date.
• Coursework in one or more of the following: RF Circuit Design, Microwave Circuits, Electromagnetics, Antenna Engineering, Microwave Measurements, RF Engineering, Radar Signal Processing, or Radar Design.
• Experience in at least one of the following technical domains:
  • RF/Microwave Design & Measurement: Designing, fabricating, or bench-testing RF/microwave circuits or components (e.g., amplifiers, filters, mixers, couplers), including S-parameter or microwave measurements using network/spectrum analyzers.
  • Antennas & Applied Electromagnetics: Modeling, simulating, or testing antennas or electromagnetic structures using computational tools (e.g., HFSS, CST Studio, ADS, FEKO) or anechoic chamber measurements.
  • Radar Architecture & Signal Processing: Modeling or implementing radar signal processing algorithms (e.g., pulse compression, Doppler processing, beamforming, CFAR, waveform design) using simulation tools (e.g., MATLAB/Simulink, Python) or embedded hardware.
  • Experience building, testing, or characterizing electronic hardware, RF circuits, or antenna systems using standard test benches or measurement facilities.
