Seeking a Senior DSP Engineer to design, implement, and field advanced processing chains for communications signals of interest (SOIs) across terrestrial, airborne, maritime-surface, and space segments. The role centers on detection, characterization, demodulation, and exploitation of tactical and strategic data-bearing waveforms in congested, contested, and degraded electromagnetic environments. Work spans algorithm development through operational software deployed against collected I/Q from wideband receivers and software-defined radios.
Responsibilities- Architect and implement DSP pipelines for detection, classification, parameterization, and tracking of communications signals across HF through Ka-band collections.
- Develop synchronization, carrier and symbol recovery, equalization, and demodulation algorithms for both well-documented and poorly characterized waveforms, including frequency-hopped, spread-spectrum, and low-probability-of-intercept / low-probability-of-detection constructions.
- Recover payload bits and reconstruct higher-layer structure from tactical and strategic data links, including line-of-sight, beyond-line-of-sight, and satellite communications carriers (protected and commercial).
- Design multi-rate channelize rs, polyphase filter banks, and wideband front-end processing suitable for high-occupancy spectrum and mixed narrow band / wideband collections.
- Characterize and mitigate real-world impairments typical of long-range and over-water paths:
Doppler from moving platforms, multipath, co-channel interference, phase noise, IQ imbalance, and low SNR. - Perform SOI development and waveform discovery against unidentified or evolving communications systems; produce reusable signal models, feature sets, and processing recipes.
- Implement and optimize algorithms in C/C++ and Python on Linux, with GPU/CUDA or equivalent acceleration where throughput or latency requires it; integrate with SDR hardware and existing mission processing frameworks.
- Validate processing chains against laboratory-generated and field-collected I/Q using quantitative metrics (detection probability, false-alarm rate, EVM, BER, protocol decode success).
- Support end-to-end integration with RF front ends, collection systems, and downstream analytic or C2 consumers; contribute to lab, ground, and occasional field test events.
- Mentor junior engineers, review designs, and translate operational collection needs into technical requirements and processing architectures.
- Document algorithms, interfaces, and performance so capabilities can be sustained and transitioned.
- Bachelor’s degreein Electrical Engineering, Computer Engineering, or a closely related discipline;
Master’s degree preferred. Equivalent experience may be considered in lieu ofa degree. - 8 years of experience required
- U.S. citizenship
- An active Top Secret / SCI clearance
- Ten or more years of professional experience developing DSP algorithms for digital communications, COMINT, or closely related SIGINT applications.
- Deep working knowledge of communications theory: modulation and coding, multiple access, synchronization, estimation and detection, channel models, and link-budget fundamentals.
- Hands-on experience demodulating and exploiting communications waveforms used for command-and-control and data exchange among surface,…
