4G/5G Network Element Platform Software

Roles and Responsibilities :

• Expertise in development and optimization of Linux based bare-metal/virtualized platform software on various CPUs/GPUs/DPUs/Network Processors/ASICs/FPGAs for 4G/5G RAN and Core network elements
• Experience with VPP, DPDK, DOCA, SRIOV, RDMA, OVS/OVN, XDP/ eBPF for processing of data plane traffic directly in user space (bypassing OS kernel) to facilitate e.g. highperformance packet processing
• Knowledge of SmartNIC**,** SoC, DPU/ FPGA/ ASIC etc. meant for CPU offload architecture which is required e.g. user plane workload acceleration, radio acceleration for fronthaul (CPRI/eCPRI) and L1
• Expertise in designing and implementing solutions using Multi-Processes and Multi-Threads
• Experience of driving root-cause analysis and optimization for packet loss, interrupt storms, NUMA imbalance, VF attachment issues, pod networking problems, time-sync instability affecting RAN or core workloads.
• Design and implementation experience of scalable, resilient, low latency, deterministic throughput, HA systems
• Networking protocols: Ethernet, IP, eCPRI, PTP, TCP/UDP/GTP/ SCTP
• Good knowledge of build environments (makefiles) and Continuous Integration/Continuous Deployment systems
