Role: We are looking for a DSP Engineer to own the definition and development of modem algorithms for our next-generation radio platform. You will work within our existing in-house SDR and FPGA infrastructure, taking substantial ownership over the modem end-to-end - from waveform definition through implementation and validation.
You will work closely with RF, FPGA, and systems engineers to integrate modem algorithms into a high-performance communications platform for our satellite ground network.
This role is a great fit for an engineer who thinks fluently in waveforms and signal chains and is comfortable moving that thinking into real implementation, without needing to own the surrounding RF hardware, data-converter, clocking, or embedded systems architecture.
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
