Description:
Xenon delivers COMINT and signal processing systems - the algorithms are the product. Everything else (the firmware, the embedded software, the hardware) exists to carry those algorithms into an environment where the spectrum is dense, the emitters are uncooperative, and the platform is moving.
This role owns that algorithmic core. You will work on detection, demodulation, classification, and geolocation of communications signals under conditions that violate most of the assumptions in the textbook: low SNR, co-channel interference, short-duration transmissions, and non-cooperative waveforms that were designed not to be easy.
You will not be handed a specification and asked to code it. You will be handed a mission problem and expected to determine what is theoretically achievable, prototype it, prove it against real data, and then carry it through to something that runs in real time on constrained hardware.
What you will do Algorithm development
Design detection, estimation, synchronization, and demodulation algorithms for communications signals across the spectrum
Develop blind and semi-blind approaches to signal parameter estimation where prior knowledge is limited or wrong
Build classification and modulation recognition capability, including approaches that degrade gracefully rather than failing silently
Performance characterization
Own the analysis that proves an algorithm works including probability of detection and false alarm curves, threshold behavior, sensitivity to model mismatch
Build and maintain synthetic signal generation and channel modeling infrastructure for repeatable evaluation
Characterize performance against recorded collections and identify where lab results diverge from field results, and why
Implementation partnership
Produce fixed-point analyses and reference models that firmware and embedded engineers can implement against
Work through the trade space between algorithmic ideal and what the target hardware can actually sustain
Review implementations against golden models and run the bit-accurate comparisons that catch problems before integration
Field and test support
Perform post-mission reconstruction and root-cause analysis when system behavior does not match expectation
Translate operator feedback into algorithmic requirements
Requirements
Minimum qualifications:
BS in Electrical Engineering, Computer Engineering, or related field
7+ years in RF signal processing with demonstrated COMINT, SIGINT, or EW application
Deep working knowledge of detection and estimation theory, modulation theory, synchronization, and channel effects
Strong MATLAB or Python prototyping skill, with the ability to write production-quality C/C++ when required
Demonstrated experience characterizing algorithm performance rigorously
Ability to obtain a TS/SCI clearance
Preferred qualifications MS or PhD with a signal processing emphasis
Experience with wideband channelization, polyphase filterbanks, and blind signal separation
Familiarity with GOTS RF analysis tooling and signal analysis workflows
Exposure to fixed-point implementation and FPGA-targeted design
Experience with GPU or SIMD acceleration of signal processing workloads
Active TS/SCI
