• 2+ years experience working with RF components and subsystems, including T/R modules, rotary joints, pedestal, filters, radiating structures, isolators, amplifiers, ADC/DAC, etc.
• Design experience in: RF systems, subsystem and/or component analysis (frequency planning, link budget analysis, transceiver architectures, cascade analysis), Electromagnetics & RF/wave propagation
• Skilled in RF component/subsystem/system test and measurement equipment and techniques (anechoic chambers, oscilloscopes, vector network analyzers, spectrum analyzers, signal generators)
• Proficiency in MATLAB and/or Python and/or other higher-level languages
• Strong mathematical, troubleshooting, written, and verbal communication skills

Nice to Have:

• Active Secret or TS/SCI Clearance
• Advanced degree in Electrical Engineering, Applied Mathematics, Physics, or a related technical discipline
• Experience with: RF systems engineering and technologies in one or more of the following areas: sensing and electronic warfare applications including electronic attack, electronic protection, cognitive EW, radar, and advanced ESM techniques, EM Field Solvers (ANSYS HFSS, Sonnet), Interacting with decision-makers and customers to translate mission needs into an end-to-end analytical solution
• Prior design experiences in: Antennas, RF Printed Circuit Boards, RF Integrated Circuits, RF Transceiver building blocks (power amplifiers, low-noise amplifiers, oscillators, mixers, filters)
• Knowledge of: Mechanical design, Designing and debugging for EMI/EMC requirements, FPGA hardware inference designs
• Background in designing for manufacturability, producibility, and cost constraints
• Ability to apply novel, innovative and interdisciplinary approaches to challenging engineering problems
• Ability to create and present briefings to customers and senior management to provide both high-level and deep technical solution explanations
