Network Systems Software Engineer

Job Description:

Responsibilities

• 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.

Qualification & Experience

• Bachelor’s or Master’s degree in Computer Science or Electronics and Communication Engineering.
• 3 to 7 years of hands-on experience in networking or systems product development.
