  • Passionate individual with strong fundamentals in signals and systems, digital communications, software development, and analog concepts. Experience with signal generators, analysers, and oscilloscopes. US Citizenship or Green Card required. Bonus points for experience with software defined radios, Python, GNU Radio, and FPGA development. Mobile and willing to work onsite in San Francisco.
  • The candidate will design signal processing for custom software defined radio hardware, collaborate with FPGA developers, model the end-to-end radio system, drive radio architecture trade studies, and optimize system performance for various markets and use cases.


  • A passion for working in a fast-paced environment and constantly learning
  • Strong fundamentals in "signals and systems" (basic transforms, filters, aliasing, analysis in both continuous and discrete domains, interpolation, decimation, etc)
  • Strong fundamentals in digital communications (modulation, coding, synchronization, fading, doppler, multiple access, channel capacity, etc)
  • Familiar with software development (some experience writing software for DSP, MCU, and/or FPGA, experience in one or more scripting languages)
  • Familiar with analog concepts (amplifiers, analog filters, gain and delay variation, reflections, compression, etc)
  • Experience working with signal generator, signal analyzer, network analyzer, oscilloscope, etc
  • US Citizenship or Green Card
  • 40 hours per week minimum
  • Must be onsite in San Francisco 3 days a week minimum
  • Don't meet them all? Not a problem. Please apply even if you do not meet all these criteria.
  • Bonus:
  • Experience with software defined radios
  • Experience with Python
  • Experience with GNU Radio
  • Experience with FPGA development (and/or embedded C)


  • Design signal processing for custom software defined radio hardware (ex. channelization, equalization, PA linearization, gain control, carrier synchronization, symbol mapping, framing, channel coding/FEC, etc)
  • Work closely with FPGA developers to implement and test the signal processing on radio hardware
  • Model the end-to-end radio system from earth to space, and back.
  • Drive radio architecture trade studies, run link budgets, optimize the radio system for maximum performance for dozens of markets and use cases around the world
