Senior Software Engineer – Networking Systems

Senior Software Engineer - Network Systems

We are seeking a Senior Software Engineer - Network Systems with strong proficiency in C/C++ and Python, and solid experience in the networking domain. The ideal candidate will be responsible for designing, developing, and maintaining software systems that power next-generation networking solutions, with a focus on performance, scalability, and reliability. Having hands-on experience in virtualized environments (VMs) — including setup, configuration, and network integration — along with the ability to design and develop robust, scalable networking software is also an essential requirement.

Key Duties and Responsibilities:

• Design and develop software modules using C/C++ for high-performance network applications.
• Part of the software also involves integrating with Python based modules.
• Work on L2–L7 networking protocols such as Ethernet, IP, TCP/UDP, BGP, OSPF, MPLS, and others.
• Collaborate closely with architecture and QA teams to define and deliver robust software components.
• Debug and resolve complex issues across multiple layers (application, transport, and network).
• Analyze crash files and debug with the team to resolve them
• Configure and troubleshoot virtual networking in virtual machine (VM) environments — bridges, TAP/TUN interfaces, VLANs, and virtual switches (like OVS).
• Deploy and test networking software inside VMs or virtualized test environments (e.g., KVM, VMware, VirtualBox, or cloud VMs).
• Collaborate with DevOps and QA teams to ensure seamless deployment, configuration, and testing workflows.
• Participate in design and code reviews, enforcing best practices for maintainable, high-quality code.
• Mentor junior engineers and contribute to technical design discussions and documentation.

Requirements:

• Bachelor’s or Master’s degree in Computer Science, Electronics, or related discipline.
• 7–10 years of hands-on software development experience in C/C++ and Python.
• Strong understanding of networking concepts and protocols — IPv4/IPv6, ARP, VLAN, TCP/IP stack, routing, switching, or network virtualization.
• Experience with Linux based systems — system programming, socket programming, and multithreading.
• Hands-on experience with packet capture/analysis tools (Wireshark, tcpdump, etc).
• Exposure to DPDK/VPP, SDN/NFV, or network appliances is a strong plus.
• Experience integrating software with network management systems (NMS), SNMP, or REST APIs.
• Familiarity with CI/CD pipelines, Git, Jenkins, Docker, Kubernetes preferred.
• Excellent problem-solving and debugging skills in distributed systems.
• Good understanding of software design patterns and performance optimization techniques.
• Strong analytical thinking and attention to detail.
• Good communication skills and ability to work in a collaborative environment.
• Proven track record of delivering production-quality software in fast-paced teams.

Preferred / Good to Have:

• Experience with VPP (Vector Packet Processing) or DPDK-based applications.
• Strong understanding of networking concepts — TCP/IP stack, routing, switching, VLANs, ARP, IPv4/IPv6.
• Proven experience with Linux/Unix systems, socket programming, and multithreaded applications.
• Hands-on experience in setting up and managing virtual machines and virtual networks — including KVM, libvirt, VMware, or VirtualBox.
• Familiarity with configuring bridges, vSwitches, TAP/TUN interfaces, and NAT or host-only networking.
• Exposure to OpenConfig, NETCONF/YANG, gRPC, or telemetry systems.
