## Description

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.

Own end-to-end signal-chain system engineering for GEO backhaul and inter-satellite cross-links. This includes algorithm development, simulation, measurement engineering, and driving the architectural transition into FPGA-ready solutions. You will serve as the technical lead for third-party vendor IPs, ensuring seamless integration and compliance with Xona requirements.

What You'll Do:

 * Algorithm & Hardware Evolution: Develop acquisition, tracking, data decoding, and measurement algorithms; collaborate across the team to drive the architectural transition from mathematical models to fixed-point, optimized FPGA designs and verifications.
 * High-Fidelity Simulation: Build Python/C++ simulations and analyze performance under low-SNR, high dynamics, interference, and multipath.
 * Integrated Architecture: Define HW/SW partitioning and system interfaces; optimize for FPGA resource utilization and timing constraints while ensuring requirements traceability.
 * Measurement Product Definition: Specify measurement products (code phase, carrier, Doppler, C/N, PRs, DRs) and validate with Navigation team.
 * Vendor & Lifecycle Management: Lead vendor SOWs, acceptance tests, integration, and compliance reviews. Document system architecture, simulations, trade studies, and verification results.
