Staff Engineer (Data Plane / VNF)

Job Description: As a Senior Software Engineer in the Data Plane team at our company, you will play a crucial role in developing high-performance Virtual Network Functions (VNFs) for multi-cloud gateways. Your focus will be on enhancing raw packet processing speed, minimizing latency, and ensuring robust stability of the IZO MCN vRouter on the VNFaaS platform. Responsibilities: - Design, develop, and maintain core data plane software for multi-cloud gateways using C/C++ and Go, emphasizing performance and reliability. - Implement and optimize high-speed packet processing pipelines utilizing modern data plane frameworks like DPDK and VPP to achieve line-rate throughput. - Dive deep into Linux kernel and networking stack to troubleshoot performance issues, fine-tune system parameters, and create efficient networking components. - Ensure performance and stability of data plane VNFs on virtualization platforms like KVM throughout the gateway's lifecycle. - Collaborate with the control plane team to integrate routing logic, security policies, and tunneling protocols (IPsec, VXLAN) into the data plane. - Mentor junior engineers and uphold a culture of technical excellence, robust design, and high-quality code. Required Qualifications: - 5+ years of systems-level software development experience, focusing on networking or high-performance data planes. - Proficiency in C/C++ and/or Go for building low-latency, multi-threaded applications. - Hands-on experience with high-performance packet processing technologies like DPDK or VPP. - In-depth knowledge of Linux networking internals including the kernel stack, sockets, and Netfilter. - Experience with virtualization technologies, especially KVM, and running network functions in a virtualized environment. - Strong understanding of L2/L3 networking protocols such as TCP/IP, Ethernet, VXLAN, and Routing. Preferred Qualifications: - Familiarity with network security protocols like IPsec. - Knowledge of container networking (CNI) and cloud-native technologies such as Kubernetes. - Experience with low-level performance analysis and optimization tools like eBPF, bpftrace, SystemTap, and gdb. - Contributions to relevant open-source projects like DPDK, VPP, OVS, FRR, etc. - Experience working in a fast-paced environment.,
