Senior Network Systems Software Engineer

• Design, develop, and enhance common networking infrastructure used by multiple Layer-2 and Layer-3 protocols, as part of a product engineering team (not network operations or IT support)
• Build and maintain shared framework components that support routing, switching, VPN, and overlay protocols rather than implementing individual protocol stacks
• Develop high-performance, low-latency system software primarily in C, focusing on efficient data structures, memory management, and scalability
• Design and optimize core data structures and frameworks used for: Packet processing pipelines, Routing and forwarding databases, Protocol state machines and control-plane infrastructure
• Work closely with protocol teams (OSPF, BGP, ISIS, EVPN, VXLAN, etc.) to provide robust and reusable infrastructure components
• Participate across the full product development lifecycle, including design, implementation, debugging, testing, and optimization
• Analyze and troubleshoot complex system-level, performance, memory, and concurrency issues
• Collaborate with system test, QA, and cross-functional engineering teams to deliver scalable and reliable networking solutions
• Learn and adapt quickly to new networking technologies, standards, and product requirements

• Bachelor’s or Master’s degree in Computer Science or Electronics and Communication Engineering
• 4 to 10 years of hands-on experience in networking or systems product development
• Strong C programming expertise (mandatory) with deep hands-on experience in writing optimized, production-quality C code, memory management, pointers, and performance tuning, debugging complex system-level issues
• Strong foundation in Data Structures and Algorithms, with practical experience designing and using lists, trees, hash tables, graphs, queues, and stacks, scalable data models for networking and systems software
• Working knowledge of C++ is a plus
• Good understanding of networking concepts and protocols, including Routing & Switching: OSPF, BGP, ISIS, VPN & Overlay: MPLS, VPLS, Layer-2 and Layer-3 VPNs, EVPN, VXLAN, Traffic & Services: Multicast, QoS, Firewall
• Solid understanding of the OSI Model and the TCP/IP protocol suite, including ARP, IP, ICMP, IGMP, TCP, UDP, SNMP, and FTP
• Experience working on routers, switches, or network operating system platforms is highly preferred
• Strong problem-solving and analytical thinking abilities
• Self-motivated with the ability to work independently and collaboratively
• Quick learner with adaptability to new technologies and evolving requirements
• Strong communication and presentation skills
• Effective team player with a product-engineering mindset
