DSP Engineer

Responsibilities:

• Own the definition and development of modem algorithms end-to-end, from requirements through implementation and validation
• Define waveform processing chains — synchronization, pulse shaping, equalization, and related signal-processing functions — for implementation on an in-house SDR platform or FPGA
• Partition and implement modem signal-processing functions across FPGA logic and embedded/host-based compute, working within the existing hardware platform
• Collaborate with RF, FPGA, and systems engineers to integrate modem algorithms into the end-to-end system and validate performance
• Develop and run communication system tests to characterize modem performance under realistic channel impairments
• Basic Qualifications:
• Bachelor's degree with 0-4 years of relevant experience in electrical engineering, computer engineering, or a related field
• Experience developing modems or waveform processing chains for SDR, wireless communications, radar, or similar RF systems
• Strong understanding of digital communications theory: CCSDS waveforms, BPSK/QPSK/OQPSK, DVB-S2, carrier synchronization, pulse shaping, equalization, and Doppler effects
• Demonstrated ability to carry waveform algorithms from analysis and prototyping through to a working implementation, rather than stopping at simulation
• Working understanding of the complete signal chain and how modem design decisions interact with RF and hardware constraints
• Experience with communication system testing and performance characterization
• Preferred Qualifications:
• Experience with bit-equivalence verification through FPGAs
• Familiarity with SDR frameworks such as GNU Radio
• Experience with real-time signal processing
• Systems programming skills in C++ or Rust, with Rust especially valued
• Experience with beamforming, radar, or electronic warfare (EW) systems
