Xona is the navigational intelligence company bringing real-time, centimeter-level certainty to any device, anywhere on Earth.
With Pulsar - the world's most advanced PNT satellite infrastructure in Low Earth Orbit - Xona will offer a future-proof, backwards-compatible global positioning system optimized for absolute precision, superior power, and robust protection.
OverviewWe're looking for a
Navigation Algorithms Engineer to join our Ground Software team.
This is a hands-on algorithm role: you'll build tools that keep an eye on constellation health and work on the core estimation pipelines, including Precise Point Positioning (PPP), that make centimeter-level accuracy possible. You'll work alongside senior navigation engineers who will mentor you as you grow from prototype-level contributions toward owning pieces of the pipeline outright.
This role is a great fit for someone with a solid foundation in statistics and estimation who wants to apply it to real satellite navigation systems.
Key Responsibilities- Constellation Monitoring: Develop tools to monitor the health, availability, and performance of the Pulsar constellation and GNSS signals in real time.
- Estimation Pipelines: Collaborate on and help validate Precise Point Positioning (PPP) algorithms and other estimation pipelines across the navigation stack.
- Collaboration & Growth: Work closely with senior navigation engineers to review results, troubleshoot algorithm performance, and build toward greater ownership of navigation subsystems over time.
Required Qualifications- MS or PhD in Aerospace Engineering, Electrical Engineering, Geomatics, Applied Mathematics, or a related field.
- Solid foundation in statistics and estimation theory (e.g., least squares, Kalman filtering) from coursework, research, or project experience.
- Familiarity programming in both C++ and Python.
- Internship, academic research, or project-based experience with navigation, estimation, or signal processing is welcomed in place of industry experience.
Desired Qualifications- Prior exposure to PPP algorithms or implementations.
- Familiarity with GNSS receiver internal mechanics or the GNSS signal processing chain.
- Familiarity with GNSS data formats (RINEX, SP3, RTCM).
- Familiarity with orbital mechanics, reference frames, and time systems.
For U.K. Roles: To comply with U.K. regulations, this role requires Baseline Personnel Security Standard (BPSS) checks, and successful candidates must be eligible to obtain UK Security Clearance (SC).
For Canada Roles: Successful candidates must obtain and hold a security clearance at the reliability status level, and pass security assessment for the Canadian Controlled Goods Program (CGP) and ITAR.
