Senior DSP Engineer

Location: Remote within DMV and Florida + Travel

Position Overview

We are seeking a Senior DSP Engineer with deep expertise in RF communications signal processing and practical, hands-on implementation experience on Xilinx UltraScale+, RFSoC, and Versal platforms. The ideal candidate holds a Master's or PhD in Electrical Engineering, Computer Engineering, Applied Mathematics, or a related field, and has a proven track record of developing and fielding innovative DSP solutions for real-world RF systems (not just simulations).

This role requires an innovative, out-of-the-box thinker, someone who can go beyond cookie-cutter DSP blocks to develop novel or nontraditional approaches when performance, latency, interference, or mission constraints demand it. The engineer will collaborate across RF, FPGA/embedded, systems, and customer teams to deliver mission-critical communications and signal processing capabilities.

This position reports to the Chief Technology Office and involves close collaboration with customers and engineering teams to deliver innovative solutions for RF Tactical & Naval Military Solutions, as well as strategic border protection applications.

Key Responsibilities

• Design, develop, and optimize DSP algorithms for RF communications signals, including waveform processing in contested and dynamic environments (e.g., filtering, synchronization, channelization, detection/estimation, demodulation/decoding, interference mitigation).
• Lead algorithm development from concept through prototype to implementation, balancing performance, latency, robustness, and computational constraints.
• Implement and validate DSP solutions on heterogeneous compute platforms including Xilinx RFSoC, UltraScale+, and Versal, leveraging PL/PS resources and hardware acceleration as appropriate.
• Collaborate with FPGA engineers to translate algorithms into hardware-realizable architectures (fixed-point design, throughput/latency optimization, resource trade studies, hardware-friendly formulations).
• Work closely with embedded software engineers to integrate real-time DSP pipelines (drivers, data movement, DMA, streaming interfaces, buffering strategies, runtime configuration).
• Develop and execute test/verification strategies using lab instrumentation and captured RF datasets; characterize performance under impairments (CFO/phase noise, multipath, fading, interference/jamming, nonlinearities).
• Develop simulation and analysis environments (e.g., MATLAB/Simulink, Python) and correlate simulation results to hardware/field behavior.
• Provide technical leadership: define architecture, conduct design reviews, mentor engineers, and communicate trade-offs clearly to stakeholders.
• Produce high-quality documentation (DSP design descriptions, algorithm specs, performance reports, ICD inputs, SBIR deliverables as required).
• Support integration, debug, and field test activities spanning DSP, RF, FPGA, and embedded software domains.

Required Qualifications

• Master's degree or PhD in Electrical Engineering, Computer Engineering, Applied Mathematics, Physics, or related field.
• 15+ years of relevant DSP engineering experience with demonstrated delivery of RF communications signal processing solutions.
• Proven practical experience processing RF communications signals (beyond academic examples), including development, validation, and performance characterization.
• Strong fundamentals in communications and statistical signal processing (detection/estimation, synchronization, spectral analysis, filtering, modulation/demodulation concepts).
• Experience implementing DSP on embedded/real-time systems and/or hardware-accelerated platforms, including Xilinx UltraScale+, RFSoC, and Versal.
• Ability to simulate and/or model DSP algorithms in a suitable environment (MATLAB, Modelsim, etc.), with the ability to define or implement fixed-point functions, where applicable
• Demonstrated ability to create innovative DSP approaches when standard methods are insufficient-creative problem solver with strong analytical rigor.
• Proficiency in at least one of: Python, C/C++, HDL (VHDL or Verilog), MATLAB (or equivalent), with disciplined software engineering practices.
• Experience working with cross-functional teams (RF, FPGA, embedded, systems) to deliver complete system solutions.
• U.S. Citizenship and an active DoD Secret (or higher) security clearance (or ability to obtain).

Additional Preferred Qualifications

• Experience with multi-carrier channelizers, DDC/DUC architectures, polyphase filter banks, efficient FFT-based processing, and real-time spectral sensing.
• Experience with timing/synchronization challenges (PPS/10 MHz disciplining, phase-coherent multichannel systems, TDOA/FDOA concepts).
• Familiarity with JESD204B/C-based high-speed converter interfaces and RF front-end integration considerations (AGC, spur mitigation, calibration).
• Exposure to electronic warfare / interference environments, adaptive filtering, beamforming concepts, or robust waveform processing under jamming.
• Experience with embedded Linux on Zynq/RFSoC/Versal platforms and real-time streaming architectures.
• Scripting and automation (Python) for test harnesses, regression, and performance sweeps.
• Working knowledge of applicable 3GPP 38.211 - 38.214 (Minimum Release 17) standards related to the 4G/5G physical layer
• Experience supporting DoD SBIR projects or similar government-funded R&D efforts.
