Spécialiste Gnss / Gnss Specialist

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.
-----------------------------------------------------------------------------------------------------
Role Description
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.
Key Responsibilities Include:
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.
You Might be a Fit if:
You have a strong background in GNSS receiver design, in both measurement and position engine development.
You are comfortable operating in a dynamic, research-driven environment with shifting technical priorities.
You take initiative on complex technical problems and enjoy producing standalone research and analysis.
You have hands‑on experience working with GNSS test equipment and conducting lab-based signal validation.
You can work effectively in a team environment, contributing to the development of state-of-the art solutions.
You communicate effectively through written reports and verbal presentations.
You are familiar with project management principles and can act as a contributor or collaborator without friction.
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.
Desired Qualifications:
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.
