  • Programming experience using any of the languages such as C, C++ and scripting languages (yaml, GO, REST)
  • Programming experience using acceleration technologies on application level and Linux stack level using dpdk, eBPF, AF-XDP
  • Knowledge on L3/L4 load balancing and L7 load balancing (Metal LB, F5, service mesh or any similar load balancing)
