Design, develop, and optimize modem firmware and software for 5G-Advanced and early 6G protocol stacks on Qualcomm's Snapdragon chipset. Work across L1/L2/L3 protocol layers to implement 3GPP-compliant features, develop real-time scheduling and resource management algorithms, and use custom scripting to dynamically reconfigure modems based on network conditions and AI-driven signals.… Requires strong C/C++ embedded systems expertise, real-time OS experience (RTOS), wireless communication principles, and the ability to debug complex field issues and optimize performance in latency-critical environments.
