  • Quick Apply

AI generated summary

  • You need strong fundamentals in signals, digital communications, and software development. Experience with analog concepts, testing equipment, and US Citizenship/Green Card required. Bonus points for SDR, Python, GNU Radio, and FPGA/embedded C experience.
  • You will design and implement signal processing for software defined radio hardware, collaborate with FPGA developers, model radio systems, and optimize performance for various markets worldwide.

Requirements

  • 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)

Responsibilities

  • 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
