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 owns the architecture, implementation, and lifecycle of multicast protocols that enable critical solutions for the Service Provider market.
This group is in the forefront of developing products that power the largest networks in the world. The networking industry is going through a massive transformation to build the next generation infrastructure to meet the needs of AI/ML workloads and continuously increasing internet users and application. We are uniquely positioned to capture that market transition.
Your Impact
As a Software Engineer in PI-Common, you will design, build, and sustain critical routing protocol and infrastructure components used across Cisco platforms.
Your work will directly impact production networks operating at massive scale across enterprise, service provider, cloud, and AI infrastructure environments. Key responsibilities include:
- Designing and implementing enhancements to multicast routing protocol.
- Building systems that scale efficiently, are secure by design, and provide solid programmability, observability and debuggability in production.
- Debugging complex system-level issues in large-scale, multi-threaded environments, including high-priority customer escalations.
- Owning issues end-to-end — from root cause analysis through fix development, validation, and deployment.
- Representing Cisco in IETF forums and technical discussions; contributing to protocol evolution and influencing standards where appropriate.
- Collaborating closely with platform, hardware, and test teams to validate performance, scale limits, and system behaviour.
- Mentoring junior engineers and
