5G gNB L2/L3 Developer - Low Latency & Throughput

Responsibilities Develop and optimize 5G NR Layer 2/Layer 3 functionalities including MAC, RLC, PDCP, RRC, and NGAP. Implement advanced L2 scheduling algorithms, HARQ mechanisms, and efficient buffer management. Collaborate on the development of UE and gNB L2/L3 stacks, ensuring robust protocol compliance and performance. Optimize network performance by enhancing throughput, reducing latency, and improving handover processes. Debug and troubleshoot protocol stack behaviors using logs and advanced tracing tools. Integrate and test L2/L3 software with the physical layer (PHY) and core network (5GC) to ensure seamless operations. Requirements 3+ years of experience in 5G NR or LTE RAN development (L2/L3) Bachelor's or Master's Degree in Computer Science, Electrical Engineering, Telecommunications, or a related field. Strong programming skills in C, C++, and experience with multi-threaded and real-time systems. Deep understanding of MAC, RLC, PDCP, RRC, NGAP protocols. Experience with L2 scheduling, HARQ, QoS, and mobility management. Familiarity with 3GPP (Rel-15 and later) specifications. Strong debugging skills with tools like Wireshark, TShark, QXDM, or similar. Experience in real-time OS (RTOS) or Linux kernel networking stack. Knowledge of DPDK, VPP, or other high-performance packet processing frameworks is a plus. Experience in O-RAN, Open RAN, or vRAN architectures is a plus. #J-18808-Ljbffr Jobtailor
