Role Responsibilities
In this role, you will be responsible for the design, development, testing, maintenance, and optimization of real-time embedded GNSS positioning software.
Key responsibilities include
Design, develop, review, and maintain production-quality GNSS Positioning Engine software in C/C++. Implement and optimize GNSS positioning algorithms, including Weighted Least Squares (WLS), Kalman Filtering (KF/EKF), and Position/Velocity/Time (PVT) estimation. Develop algorithms and software for processing GNSS measurements, including pseudorange, Doppler, carrier-phase, satellite ephemeris, clock, atmospheric, and other measurement corrections. Develop and optimize GNSS/INS and multi-sensor fusion algorithms using inertial sensors and other positioning technologies. Contribute to advanced positioning technologies including multi-frequency GNSS, hybrid positioning, sensor-assisted navigation, AI/ML-enhanced positioning solutions and emerging XR use cases. Work closely with GNSS systems engineers to translate positioning algorithms and system concepts into efficient, robust, production-quality embedded software. Collaborate with the GNSS Measurement Engine team to consume and process GNSS observables and optimize end-to-end positioning performance. Develop robust algorithms for satellite selection, measurement weighting, outlier detection and rejection, fault detection, integrity monitoring, and positioning error mitigation. Analyze and improve positioning accuracy, availability, robustness, convergence time, and reliability under challenging GNSS environments including urban canyons, indoor, and high-dynamic scenarios. Diagnose and resolve complex system-level positioning and performance issues using GNSS measurements, logs, simulations, and field-test data. Develop software within a real-time, multi-threaded embedded architecture, including inter-process communication and multiple software and firmware interfaces. Contribute to software architecture, interface design, design reviews, code reviews, unit testing, and development methodology. Optimize positioning software for CPU/MIPS utilization, memory footprint, latency, and power efficiency. Work closely with systems, software, firmware, hardware, validation, and product teams to commercialize positioning technologies across Qualcomm platforms.
