About The Position

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.
Xona is seeking an analytical and self-driven GNSS Specialist with a passion for solving technically complex problems in satellite navigation. The ideal candidate thrives in fast-paced, research-heavy environments, and can confidently work independently and collaboratively to deliver mission-critical insights. As a member of the product team, the chosen candidate will be expected to conduct deep-dive analyses on cutting-edge timing and positioning systems, participate in analytical and theoretical studies involving topics related to LEO-PNT and its wide range of applications — from reliable timing for critical infrastructure to exploiting dynamics to achieve precise positioning.

Requirements

• Master’s Degree or PhD in Aerospace Engineering, Electrical Engineering, Geomatics Engineering, Mechanical Engineering, or other relevant fields.
• 2+ years of experience working in GNSS.
• Experience with theoretical analysis of GNSS performance in various environments using Python, C, C++ or MATLAB.
• Availability to support occasional rapid-turnaround technical assessments.

Nice To Haves

• Experience writing and presenting technical content to both internal and external stakeholders.
• Prior experience with GNSS timing and UTC traceability.
• Experience with precision GNSS corrections modeling and application.
• Theoretical understanding and practical experience with multipath characterization, reflection modeling, and signal-level or measurement-level mitigation techniques.
• A demonstrated ability to work independently on targeted research projects.
• Strong project management skills and ability to collaborate.
• Experience with hardware testing, including field testing and GNSS simulators.
• Experience with the practical use of Linux-based systems.

Responsibilities

• Assisting the execution of time-sensitive novel LEO PNT-related analyses to support ongoing and future company objectives.
• Preparing technical resources and materials related to Pulsar-based PNT including contributing to white papers, internal reports, and technical documentation, leading detailed analysis on key GNSS research topics.
• Partner with business teams on research driven customer demonstrations, including feasibility analysis, test plan development, onsite execution, and delivery of rigorous technical reports.
