Staff Software System Engineer (Networking)

Join a high-performance engineering team building next-generation network operating systems for leading data-networking platforms.
You will design and implement embedded software spanning control-plane (protocols & network logic) and data-plane (packet forwarding & resource management) components that power carrier-grade switching and routing solutions

Key Responsibilities

• Design, develop, and maintain software for switching and routing platforms.
• Build scalable control-plane modules (L2/L3 protocols, routing, management).
• Implement high-performance data-plane features – packet forwarding, QoS, ACL, traffic management.
• Participate in system architecture and design reviews; propose improvements.
• Integrate and interact with third-party protocol stacks or SDKs.
• Debug performance bottlenecks, memory leaks, and inter-process issues.
• Collaborate cross-functionally with Hardware, QA, and Product teams to validate features and interop requirements.
• Prepare design documents and drive feature sign-offs through the entire product life cycle.

Core Technical Expertise

Control Plane Areas:

• L2 protocols – STP/MSTP/RSTP, 802.1p/q/v, 802.1x, 802.3ad (LACP), IGMP, ERPS
• L3 protocols – IPv4/IPv6, OSPF, BGP, PIM, ISIS, VRF, L3VPN
• Routing algorithms and data structures

Data Plane Areas:

• Packet forwarding pipeline design and resource management (TCAM, packet buffers, RIB/FIB, ACL)
• Policy-based routing (PBR), QoS, Rate-limiting, MPLS, VPLS, VLL, VXLAN, SDN/OpenFlow
• High availability and in-service software upgrade (ISSU)

Programming & Systems:

• Strong C/C++ programming skills (Mandatory)
• Linux OS internals and multi-threaded development
• Python or Shell scripting for automation (preferred)
• Debugging tools (gdb, valgrind, profilers)
• Familiarity with microservices and Go language is a plus

Nice to have & Requirements

• Experience with network ASIC SDKs or traffic manager drivers
• Exposure to automated unit testing frameworks
• Understanding of REST APIs and system integration for management interfaces
• Working knowledge of virtualized network functions (VMs, containers).
• Experience with network ASIC SDKs or traffic manager drivers
• Exposure to automated unit testing frameworks
• Understanding of REST APIs and system integration for management interfaces
• Working knowledge of virtualized network functions (VMs, containers)

Qualifications

• B.E./B.Tech or M.E./M.Tech in Computer Science, Electronics or related field
• 4–12 years of hands-on experience in Networking / Telecom software development (embedded systems or network management)
• Strong problem-solving and analytical skills
