About the role

Daily life is underpinned by satellite navigation infrastructure, the global economy relies on GNSS and in the UK it is worth an estimated £13,622m per year, supporting everything from consumer applications, to transportation, to time sync for critical infrastructure. As these industries progress towards autonomy, the performance and security demands of their Position, Navigation and Timing (PNT) systems are increasing beyond what GNSS can support, leaving a need for a cost-effective global solution. Xona is seeking a GNSS Engineer to join our growing UK team. As a member of this team, you will collaborate with our navigation and software engineers in the support of the development and certification of next generation LEO GNSS downstream applications. You will plan and conduct GNSS testing across lab and field environments, working closely with partners and early customers to shape hardware selection and test design, and to rigorously evaluate and characterize performance across varying operational conditions. Key Responsibilities include: Lab Testing & Simulation: You will test and verify GNSS receivers and simulators to ensure performance across both controlled setups and representative operational scenarios. You will be responsible for designing simulation activities and analyzing results from simulations and testing across commercial programs. Software Development: You will be supporting software development and engineering activities which may include algorithm development, test automation or Digital Signal Processing (DSP) for GNSS and Pulsar signals. Customer Testing & Trials: You will design, plan, and execute GNSS testing activities across lab and real-world environments. This includes selecting appropriate receiver hardware, defining robust test methodologies, and developing test cases that assess performance under varying conditions.

Requirements

  • Minimum of BS / BEng in Electrical, Computer Science, Geomatics, Aerospace, or related field, and relevant experience in a Position, Navigation and Timing Industry.
  • Familiarity with GNSS receivers and GNSS Interface Control Documents (ICD) and data/file formats such as RINEX navigation and observation files, sp3, NMEA and others.
  • Experience with Python or C++ (OOP is a plus), familiarity with Git version control and the Git workflow, some familiarity with CICD and Docker is advantageous.
  • Familiarity with hardware simulation, RF lab testing, system level verification testing, hardware-in-the-loop testing, data processing, and field testing.
  • Must have right to work in the UK.
  • Must be willing to travel for customer engagement and environment-specific field testing.
  • Desirable but not essential:
  • Basic knowledge of GNSS signal processing chain and positioning algorithms or experience in LEO satellite signals in navigation.
  • Experience with novel GNSS simulator and receiver testing.
  • Experience in GNSS RF recording tools and workflows, including the generation, processing and replay of IQ data files.
  • Experience in Cryptography or Secure Communications is advantageous.
  • Experience with Software Defined Radios (SDR) GNU Radio and Software Defined Receivers.
