Principal RF Engineer, EW

The role

You will design and develop complete RF radio architectures from requirements through production. This includes architecting signal chains, modeling circuits, and owning radio PCBA design and test through the full lifecycle.

What you will do

• Design and develop complete RF radio architectures from requirements through production
• Architect and design RF up-conversion and down-conversion signal chains
• Model, simulate, analyze, design, test, and optimize active and passive RF and/or mixed signal circuits
• Select, characterize, and integrate high-speed data converters and associated circuits
• Design and optimize clock trees, reference oscillators, and LO/synthesizer architectures
• Perform system-level spur analyses and develop mitigation strategies
• Own radio PCBA design and test through the full lifecycle
• Assist with feasibility studies, requirements definition, and system integration

Required qualifications

• B.S. Electrical Engineering or equivalent
• 7+ years experience
• Experience designing complete RF receiver and/or transmitter signal chains using common architectures
• Experience with off the shelf discrete RF components like LNAs, filters, mixers, PLLs / synthesizers, oscillators, amplifiers, variable attenuators, switches, power detectors, and limiters
• Experience with high-speed data converters (ADC/DAC)
• Experience with synthesizer and LO design including PLL loop filter optimization, phase noise analysis, and spur management
• Experience with schematic capture, board bring up, test, and optimization
• Experience with circuit modeling and simulation using tools like Ansys Electronics Desktop (Nexxim, SiWave) and Cadence AWR Microwave Office
• Proficient with RF test equipment including VNAs, spectrum analyzers, signal generators, power meters, and oscilloscopes
• Must be able to obtain and hold a U.S. Secret security clearance

Nice to have

• Experience with 3D EM modeling and simulation (Ansys HFSS, CST, Feko)
• Nonlinear circuit simulation (harmonic balance, envelope) using tools like AWR Microwave Office
• Familiar with matching circuit, RF filter design, and feedback / control loop design (AGC, ALC, power control)
• Experience with RF shielding, cavity design, and isolation techniques for leakage mitigation
• Experience with NPI, manufacturing test development, and production transitions
• Familiar with FPGA or digital backend integration with RF front ends
• Experience with PCB design / layout and guiding layout engineers
• Familiar with programming languages like Python for analysis and test automation
• Familiar with embedded Linux

Benefits

• Comprehensive, competitive benefits package available at little to no cost to employees
