GNSS (GPS) creates upwards of $500B in economic value in the US every year, supporting everything from consumer applications, to transportation systems, to time sync for critical infrastructure. As these industries progress towards autonomy the performance and security demands of their navigation systems are increasing beyond what GNSS can support, leaving a need for a cost-effective global solution.

Using lessons we've learned at places like SpaceX and Blue Origin, Xona is constructing a modern satellite network at the rapid pace of the new space industry leveraging the recent wave of technology and regulatory advancements. Building on our patent pending small satellite architecture, we are developing a robust and accurate service that is an independent alternative to GNSS rather than a correction, solving the longstanding challenge of obtaining a reliable high accuracy solution from the very fragile GNSS signals. Our satellite system will provide the first ever high-accuracy global navigation and timing services with the security and resilience modern applications need to operate safely at scale.

At Xona you will develop state-of-the-art hardware and software solutions to solve real problems that can have a massive world impact. Xona is driven by the mission to enable modern devices to operate safely in any environment, anywhere on Earth, and unlock the true potential of the age of autonomy.

Xona is looking for a GNSS Receiver Engineer to join the team to bring Xonas space-based receiver capabilities to life. As part of the team, you will design and implement the signal processing algorithms required for the acquisition and tracking of Xonas proprietary GNSS waveform on a satellite in space. From simulations in software through deployment on an FPGA platform, you will work alongside hardware and software teams to integrate and test your designs on flight payloads.

Desired Qualification (not all are expected):

  • Understanding of the principles of GNSS radio occultation measurements
  • Prior work on RF-related FPGA designs for space applications
  • Experience with HDL simulation tools such as modelsim
  • Experience with DSP simulation tools/languages such as MATLAB or Python
  • Mixed-signal and analog/RF lab test experience; usage of oscilloscopes and spectrum analyzers

Required Qualifications:

  • 5 years of FPGA development experience in VHDL/Verilog, spanning the complete build flow from synthesis, placement, and routing to timing constraints and timing closure
  • Proficient in C/C++ to interact with and test FPGA designs
  • Knowledge of GPS/GNSS receiver implementations
  • Digital Signal Processing knowledge (filtering, sample rate conversions, etc.)
  • To comply with U.S. Government space technology export regulations, applicant must be a U.S. citizen, lawful permanent resident of the United States (i.e. Green Card holder), or other protected individual as defined by 8 U.S.C. 1324b(a)(3).
