Principal RF Subsystem Lead Engineer at Raytheon Tucson, AZ
Raytheon, Tucson, Arizona, United States, 85718
Job Description
The Principal RF Subsystem Lead Engineer at Raytheon leads the design, analysis, and implementation of advanced RF subsystems and embedded signal processing algorithms for missile products. The role involves system-level decomposition, performance testing in various environments, and applying specialized RF and statistical techniques to meet mission requirements. The engineer also provides technical leadership, collaborates across disciplines, and interfaces with government and program leadership in a secure, onsite environment. Responsibilities
Specify, design, and test advanced RF sensors, subsystems, and embedded signal processing algorithms across frequencies from MHz through millimeter-wave. Decompose system-level requirements into detailed RF component and algorithm requirements. Measure RF components/sensors/subsystems, including performance in chamber and range environments. Perform modeling and analysis of link budgets, RF cascades, signal processing chains, antenna patterns, phase noise, receiver sensitivity, transmitter power, spurious signals, modulation, isolation, and ADC characteristics. Utilize statistical techniques such as Monte Carlo simulation to perform sensitivity analyses and execute design trades. Support software and configurable logic teams with implementation and maturation of signal processing algorithms in tactical hardware. Support simulation team with implementation and integration of RF HW models into system performance simulation. Support production team with troubleshooting activities, assessing impact of non-compliant HW on system performance, and requirements re-allocation. Qualifications
Bachelor of Science degree in Technology, Engineering, or Mathematics (STEM) A minimum of 8 years of prior relevant experience, or an advanced degree in a related field and a minimum of 6 years of experience that includes the following:
Design, integration, and / or test of RF sensors, subsystems, and / or signal processing algorithms
Preferred Qualifications
Knowledge of RF technologies, including circuit card assemblies (CCAs), waveguides, planar/printed antennas, RF modules, and/or monolithic microwave integrated circuits (MMICs). Experience performing Link Budget and Radar Range Equation analyses. Experience in design and analysis of signal processing chains including digital receivers, digital filters, Fourier analysis, matched filters, modulation/demodulation, correlators, signal and noise modeling. 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. Experience interacting across engineering disciplines (e.g. Systems, Mechanical, SW, Configurable Logic, Algorithms, etc.) to define RF subsystem and signal processing requirements and evaluate performance RTX is an Equal Opportunity Employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability or veteran status, or any other applicable state or federal protected class.
