Responsibilities
- Design, develop, review, maintain, test, and optimize production-quality real-time embedded GNSS Positioning Engine software in C/C++.
- Implement and optimize Weighted Least Squares, Kalman Filter/EKF, PVT estimation, GNSS/INS, and multi-sensor-fusion algorithms.
- Process GNSS measurements including pseudorange, Doppler, carrier phase, satellite ephemeris, clock, and atmospheric corrections.
- Develop satellite selection, measurement weighting, outlier rejection, fault detection, integrity monitoring, and positioning-error-mitigation algorithms.
- Analyze and improve positioning accuracy, availability, robustness, convergence time, and reliability in urban, indoor, and high-dynamic environments.
- Diagnose system-level positioning and performance issues using measurements, logs, simulations, and field-test data.
- Develop within real-time, multithreaded embedded architectures with inter-process communication and software/firmware interfaces.
- Contribute to software architecture, interface design, design reviews, code reviews, unit testing, and development methodology.
- Optimize software for CPU/MIPS utilization, memory footprint, latency, and power efficiency.
- Collaborate with systems, software, firmware, hardware, validation, and product teams to commercialize positioning technologies.

About Qualcomm
Qualcomm is a public semiconductor company headquartered in San Diego, founded in 1985, that designs and sells wireless chipsets and platforms for mobile devices, automotive, IoT, and networking, notably the Snapdragon application processors and 5G modems. It also licenses a large portfolio of cellular patents to device makers, generating revenue alongside chip sales; its technology underpins many Android smartphones and emerging automotive and edge-compute systems, and it trades on NASDAQ as QCOM.
