We are building a global network of phased array ground stations that enable real-time, reliable communication for satellite missions such as national security, global connectivity, and disaster response. With a vertically integrated approach, Northwood designs, builds, and rapidly deploys scalable systems that power the next generation of space missions. If you like solving complex challenges and seeing your work deployed around the world with real impact, Northwood is the place to do it.\nRole:\nWe are looking for a Senior 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.\nYou will work closely with RF, FPGA, and systems engineers to integrate modem algorithms into a high-performance communications platform for our satellite ground network.\nThis 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.\nResponsibilities:\nOwn the definition and development of modem algorithms end-to-end, from requirements through implementation and validation\n\nDefine waveform processing chains - synchronization, pulse shaping, equalization, and related signal-processing functions - for implementation on an in-house SDR platform or FPGA\n\nPartition and implement modem signal-processing functions across FPGA logic and embedded/host-based compute, working within the existing hardware platform\n\nCollaborate with RF, FPGA, and systems engineers to integrate modem algorithms into the end-to-end system and validate performance\n\nDevelop and run communication system tests to characterize modem performance under realistic channel impairments\n\nBasic Qualifications:\nBachelor's degree with 5+ years of relevant experience in electrical engineering, computer engineering, or a related field\n\nExperience developing modems or waveform processing chains for SDR, wireless communications, radar, or similar RF systems\n\nStrong understanding of digital communications theory: CCSDS waveforms, BPSK/QPSK/OQPSK, DVB-S2, carrier synchronization, pulse shaping, equalization, and Doppler effects\n\nDemonstrated ability to carry waveform algorithms from analysis and prototyping through to a working implementation, rather than stopping at simulation\n\nWorking understanding of the complete signal chain and how modem design decisions interact with RF and hardware constraints\n\nExperience with communication system testing and performance characterization\n\nPreferred Qualifications:\nExperience with bit-equivalence verification through FPGAs\n\nFamiliarity with SDR frameworks such as GNU Radio\n\nExperience with real-time signal processing\n\nSystems programming skills in C++ or Rust, with Rust especially valued\n\nExperience with beamforming, radar, or electronic warfare (EW) systems\n\nAdditional Information:\nIf you need a reasonable accommodation as part of your application for employment or interviews with us, please let us know.\nTo conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.\nNorthwood Space is an Equal Opportunity Employer;
