Cisco is seeking an experienced Software Test Engineer to own the quality validation of IOS XR routing, platform infrastructure, optics, and Layer 0 and Layer 1 capabilities. You will work with cutting-edge routing technology to deliver stable, scalable, and production-ready networking solutions for global carrier-grade platforms.
Key Responsibilities
Design and implement functional, system, regression, scale, performance, interoperability, resiliency, and high-availability tests for IOS XR routing and L0/L1 test features.
Develop reusable and scalable test automation using Python and frameworks such as pyATS, Genie, or equivalent tools.
Build and maintain physical, virtual, containerized, and cloud-based test environments using Linux, Docker, Kubernetes, clustering technologies, VMware, OpenStack, and network simulation platforms.
Solve 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.
Work on Network automation, algorithmic thinking and Analytics applications derived from customer use cases.
Requirements
Bachelor’s or master’s degree in Computer Science, Electrical Engineering, Computer Engineering, Telecommunications, or a related technical field.
Eight or more years of experience in software engineering, network product testing, test automation, or quality engineering.
Experience configuring and solving Cisco IOS XR or another carrier-grade network operating system.
Advanced Python programming skills for test automation, scripting, API interaction, data analysis, and troubleshooting.
Experience developing system, scale, performance, resiliency, and high-availability test scenarios.
Strong Linux or Unix skills and experience with Git, code reviews, debugging, and CI/CD pipelines.
Working knowledge of cloud, containerization, virtualization, and clustering technologies, including Docker, Kubernetes, VMware, and OpenStack.
Familiarity with AI coding assistants such as GitHub Copilot or equivalent tools.
Excellent experience in Layer-0 and Layer-1 traffic generators and analysers such as Viavi, Agilent, Spirent, and IXIA.
Preferred Qualifications
Experience testing Optical and routing capabilities on Cisco IOS XR platforms such as Cisco 8000, ASR 9000, NCS 5500/5700 and NCS1K.
Experience with traffic generators and subscriber-simulation tools such as IXIA, Spirent, Viavi, or JDSU.
Strong knowledge of Layer 0 and Layer 1 testing along with platform and optics test skills.
Experience with Datapath, model-driven telemetry, and network programmability.
Familiarity with scale and performance characterization.
