Job description
Meet the Team
The Cisco cnBNG Solution Testing team validates carrier-grade broadband solutions running on IOS-XR routing platforms, including Cisco 8000, ASR 9000, and NCS 5500/5700. Our focus is ensuring that cnBNG solutions meet demanding service-provider requirements for functionality, scale, performance, resiliency, interoperability, and operational readiness. We validate the cnBNG solution end-to-end across Control Plane and User Plane functions, subscriber protocols, forwarding, high availability, and platform infrastructure. We operate at the intersection of software, hardware, networking, and customer deployments, with an automation-first approach and responsible adoption of AI-assisted engineering practices.
Your Impact
As a Software Engineer in the cnBNG Solution Testing team, you will own end-to-end solution, scale, performance, and resiliency validation of cnBNG deployments.
You will design sophisticated service-provider network topologies, develop comprehensive test strategies, automate large-scale subscriber and traffic scenarios, and validate the system under realistic customer workloads. You will work extensively with traffic-generation platforms such as Keysight IXIA and Spirent, analyze system and forwarding performance, identify bottlenecks, and collaborate with development teams to drive defects to resolution.
