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. ## Related Videos - [Coffee with Developers - Stephen Jones - NVIDIA](https://www.wearedevelopers.com/videos/1303-coffee-with-developers-stephen-jones-nvidia) - [More efficient software for more efficient microchips](https://www.wearedevelopers.com/videos/1164-more-efficient-software-for-more-efficient-microchips) - [Android beyond mobile: Cars, TVs, and Wearables](https://www.wearedevelopers.com/videos/553-android-beyond-mobile-cars-tvs-and-wearables) - [Strange New Worlds: shaping the future of the digital age](https://www.wearedevelopers.com/videos/677-strange-new-worlds-shaping-the-future-of-the-digital-age) - [Remote Driving on Plant Grounds with State-of-the-Art Cloud Technologies](https://www.wearedevelopers.com/videos/251-remote-driving-on-plant-grounds-with-state-of-the-art-cloud-technologies) - [Build Delightful Mobile Experiences with Kotlin, Realm, and Atlas Device Sync](https://www.wearedevelopers.com/videos/694-build-delightful-mobile-experiences-with-kotlin-realm-and-atlas-device-sync) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [The Best X (Twitter) Accounts for Developers](https://www.wearedevelopers.com/magazine/294-the-best-x-twitter-accounts-for-developers) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Dev Digest 134 - Where pixels sing?](https://www.wearedevelopers.com/magazine/477-dev-digest-134-where-pixels-sing) - [How software is steering vehicle technology](https://www.wearedevelopers.com/magazine/515-how-software-is-steering-vehicle-technology) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated)
