Responsibilities
Design, validate & deliver EW payloads end-to-end: RF front-ends and wideband receivers for Electronic Support Measures/Electronics Intelligence/Communications Intelligence systems
Develop Electronics Attack/Electronic Countermeasures modes (smart jamming, deceptive techniques), frequency agility, notch/adaptive filters, and cognitive EW that learns in-the-loop
Design characterize and deliver channelizers, wideband detection/classification, LPI/LPD intercept, and MIMO/digital-array algorithms in MATLAB/Python/C++ and accelerate on FPGA/RFSoC/GPU
Own requirements, ICDs, and verification from concept through delivery
Track and insert advances in MMIC/ RF SoC devices and associated technologies, adaptive beamforming, RF machine learning, and resilient PNT for GPS-denied ops
Qualification
Required
BS/MS in Electrical Engineering, Computer Engineering, or related field
Receiver design across analog/RF/mixed-signal domains: mixers, PLLs/LOs, gain/linearity/noise trades; ability to turn simulations into flight-worthy, Tier 1 deliverable hardware
Channelizers & wideband architectures: filter banks, analog/digital downconversion, sample-rate planning, clocking/synchronization across nodes
Willingness to support critical test events that occasionally require extended hours/weekends
To Conform to US Government Regulations, applicant must be a (i) U.S. Citizen or National or (ii) U.S. lawful, permanent resident (aka green card holder)
