Sr.DSP Engineer (Hybrid, Aberdeen Proving Ground Maryland)
About The Position
We are seeking a Digital Signal Processing (DSP) Engineer to design, implement, and optimize advanced baseband and waveform-level signal processing for next-generation context-aware software-defined radios (SDR) and adaptive electronic warfare (EW) systems. This role is central to evolving an existing channel emulator into an active EW platform and delivering TRL-6 Army Software Defined Radio Head (SDRH) architectures supporting wideband, multi-band, and multi-antenna operations. In addition to core SDR and EW responsibilities, this position will support the development of Low Earth Orbit (LEO) Non-Terrestrial Network (NTN) emulation capabilities within Fairwinds’ custom-built, FPGA-based RF Propagation Channel Emulator. The DSP Engineer will design and implement signal processing models for LEO satellite communications, including high-Doppler dynamics, rapidly time-varying propagation delay, frequency offset, phase noise, beam handover effects, and space-to-ground multipath conditions. This effort supports validation of LEO waveforms, PNT resilience techniques, and resilient satellite communications in contested environments.
Requirements
- Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or related field
- Strong background in digital communications and signal processing
- Experience with SDR frameworks and waveform development
- Must possess, or be eligible to obtain, at minimum an active DoD / DoW Secret Security Clearance.
Responsibilities
- Design and implement real-time DSP algorithms for OFDM, QAM, PSK, and custom waveforms
- Develop coherent and non-coherent jamming techniques including record/replay, noise, chirp, and interference waveforms
- Implement channel emulation models (multipath, Doppler, delay, SNR variation)
- Enable arbitrary waveform generation using DDR-backed buffers
- Support multi-antenna and beamforming signal processing (SISO through 4x4 MIMO)
- Collaborate on HW/SW co-design targeting AMD/Xilinx RFSoC and Versal platforms
Benefits
- Competitive compensation packages include comprehensive benefits, paid time off, retirement plans, and flexible work arrangements where mission allows.
