Senior Manager - Staff Engineer

As a Senior Software Engineer at Tata Communications, you will be an integral part of the Data Plane team, contributing to the development of high-performance Virtual Network Functions (VNFs) that serve as multi-cloud gateways. Your primary focus will be on designing and maintaining core data plane software in C/C++ and Go, ensuring exceptional performance, low-latency, and reliability. Your responsibilities will include optimizing packet processing pipelines using modern data plane frameworks like DPDK and VPP to achieve line-rate throughput. You will delve into Linux networking internals, troubleshoot performance issues, fine-tune system parameters, and build efficient networking components. Additionally, you will ensure the performance and stability of data plane VNFs running on virtualization platforms like KVM throughout the gateway lifecycle. Collaboration with the control plane team is key, as you will integrate routing logic, security policies, and tunneling protocols into the data plane. In addition to your technical contributions, you will also mentor junior engineers, fostering a culture of technical excellence, robust design, and high-quality code. To excel in this role, you should possess 5+ years of experience in systems-level software development with a networking focus, proficiency in C/C++ and/or Go for building low-latency applications, and hands-on experience with packet processing technologies like DPDK or VPP. Deep knowledge of Linux networking internals, virtualization technologies (especially KVM), and L2/L3 networking protocols is essential. Preferred qualifications include familiarity with network security protocols, container networking, cloud-native technologies, low-level performance analysis tools, and contributions to relevant open-source projects. Experience in a fast-paced environment will be advantageous as you navigate the challenges and opportunities in this role.,
