Senior DSP Engineer
Owns end-to-end modem algorithm definition, implementation, and validation for a high-performance satellite communications ground-network platform. Requires a bachelor’s degree, 5+ years of relevant experience, strong digital communications expertise, and experience deploying waveform processing into SDR or FPGA systems.
About the job
Responsibilities
- Own the definition and development of modem algorithms end-to-end, from requirements through implementation and validation.
- Define waveform processing chains, including 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 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.
Requirements
- Bachelor's degree in electrical engineering, computer engineering, or a related field.
- 5+ years of relevant experience.
- Experience developing modems or waveform processing chains for SDR, wireless communications, radar, or similar RF systems.
- Strong understanding of digital communications theory, including CCSDS waveforms, BPSK, QPSK, OQPSK, DVB-S2, carrier synchronization, pulse shaping, equalization, and Doppler effects.
- Ability to carry waveform algorithms from analysis and prototyping through working implementation.
- Working understanding of the complete signal chain and interactions between modem design decisions and RF or hardware constraints.
- Experience with communication system testing and performance characterization.
Nice-to-haves
- 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, especially Rust.
- Experience with beamforming, radar, or electronic warfare systems.
Compensation
- Annual salary range: $140,000–$226,000.
