Meet the Team
The DSE Platform Independent Common (PI-Common) group develops high-performance, platform-independent system software that runs across Cisco’s flagship routers and switches. We design and deliver core routing protocols and infrastructure components that power Cisco’s Mass Scale Infrastructure, Cloud Networking, and Network Experience portfolios.
Our team works on key control-plane technologies including IGP routing protocols such as OSPF, IS-IS, EIGRP and RIP, BGP-LS, First Hop Redundancy Protocols such as HSRP, VRRP and GLBP, and routing infrastructure components such as route-policy frameworks, prefix handling, filtering, and control-plane scalability mechanisms.
These components form the foundation of networking deployments across enterprise, service provider, cloud, and AI infrastructure environments, where scale, resiliency, security, programmability, and operational debuggability are critical.
Your Impact
As a Software Engineer in PI-Common,



you will contribute to the development and maintenance of routing protocol and routing infrastructure software used across Cisco platforms. You will work with senior engineers to build reliable, scalable, and debuggable control-plane software. Key responsibilities include:
Developing features, enhancements, and defect fixes for IGP protocols, BGP-LS, FHRP technologies, and routing infrastructure components.
Writing clean, productive, maintainable code in C/C++ for multi-threaded, system-level software environments.
Contributing to routing infrastructure components such as route-policy handling, filtering, prefix processing, and control-plane integration modules.
Debugging software issues using logs, traces, core files, protocol state, and platform-level diagnostics.
Participating in root cause analysis for defects and customer-found issues, with guidance from senior engineers.
Building unit, functional, regression, and scale validation coverage for protocol and infrastructure changes.
