Meet the Team
The Cisco IOS XR Routing and BNG Test Team ensures the reliability, scalability, performance, and resiliency of Cisco’s carrier-grade routing platforms. We work closely with software developers, architects, product managers, and customer-facing teams to deliver comprehensive, end-to-end validation across Layer 2, Layer 3, routing, subscriber-management, and network-service technologies for service providers, hyperscalers, and web-scale customers operating some of the world’s largest and most demanding networks.
Our team values technical depth, automation-first engineering, continuous learning, collaborative problem-solving, and responsible adoption of AI-assisted development practices.
Your Impact
As a Software Test Engineer, you will own the quality validation of IOS XR routing and Broadband Network Gateway capabilities. You will design test strategies, develop automation, validate complex customer scenarios, investigate system-level failures, and provide data-driven release recommendations.

- Validate control-plane, forwarding-plane, subscriber-scale, traffic, failover, software upgrade, rollback, process restart, route churn, and subscriber churn scenarios.
- Troubleshoot complex issues using IOS XR logs, protocol traces, packet captures, telemetry, RADIUS transactions, crash information, and system-resource data.
- Validate model-driven interfaces and telemetry using YANG, NETCONF, RESTCONF, gNMI, gRPC, OpenConfig, and native IOS XR models.
- Integrate automated tests into CI/CD pipelines, code reviews, version control, and regression testing.
- Use approved AI coding assistants and engineering agents for test generation, automation development, log analysis, defect triage, and documentation.
- Apply foundational knowledge of generative AI, AI agents, MCPs, reusable AI skills, prompt and context management, and responsible validation of AI-generated output.
- Collaborate across engineering teams, review test designs and automation code, mentor junior engineers, and communicate product-quality risks and release readiness.
