• Develop and implement DSP algorithms including: Filtering, modulation/demodulation, and waveform processing
• Detection, estimation, and classification techniques
• Spectral analysis and signal extraction in noisy environments
• Support end-to-end signal chain design (antenna → RF front end → IF/baseband → processing)
• Develop system-level models to evaluate signal-to-noise ratio (SNR), interference, and performance trade-offs
• Perform simulation and analysis for: Phased array systems and beamforming, Direction finding (DF) and geolocation, Electronic beam steering and adaptive systems
• Validate designs through simulation, lab testing, and field experimentation
• Support integration of RF hardware with DSP and software components
• Analyze collected RF data to assess system performance and identify issues
• Collaborate on test planning, execution, and results analysis
• Interface with test engineers to refine measurement strategies and validate models
• Work closely with: RF hardware engineers (front-end design, PCB, test), Antenna engineers (array design, beamforming), Software/embedded teams (SDR, FPGA, system control)
• Contribute to system architecture, requirements development, and trade studies
• Support proposal development, IRAD efforts, and technical documentation

Qualifications

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Physics, or related field and 5 years experience
• Strong foundation in digital signal processing (DSP) and RF systems
• Experience with: MATLAB, Python, or similar for modeling and analysis, Signal processing techniques (filtering, FFTs, modulation schemes, etc.), RF system analysis and integration
• Ability to interpret and analyze real-world RF data and system performance

Preferred Qualifications

• Experience with: Software Defined Radio (SDR) development, FPGA or embedded implementations of DSP algorithms, Phased array systems, beamforming, or direction finding, Electronic warfare (EW), radar, or communications systems
