Your work will help ensure that Cisco delivers stable, scalable, and production-ready networking solutions. You will also mentor junior engineers, improve test frameworks, and use modern AI-assisted tools to accelerate engineering and solving workflows.
What You Will Do
Design and implement functional, system, regression, scale, performance, interoperability, resiliency, and high-availability tests for IOS XR routing – Platform Infra/Optics, 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
Strong in Software engineering test methodology and process knowledge
Minimum Qualifications
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.
Basic understanding of generative AI, AI agents, MCP, reusable skills, and responsible AI practices.
Strong knowledge of software development life cycle.
Strong analytical, solving, communication, and multi-functional collaboration skills.
Deep understanding of customer deployments, operations and the ability to translate brown field/green field deployments into test strategy with high efficacy
Quick learner with an open mind to "grey box" testing, bringing in strategic on-the-box, off-the-box views that reflect the state of IOS-XR systems.
Experience in test engineering concepts and methodologies including test planning, test case design, test execution and test automation
Excellent experience in Layer-0, Layer-1 traffic generators and analysers (e.g. Viavi, Agilent, Spirent, IXIA, etc.)
Strong written, verbal communication, and interpersonal skills
Results oriented with a high degree of accountability, dedication and responsibility
Industry certification such as CCNA/CCNP/CCIE/JCNA/JCIE will be a huge plus
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 or Spirent or Viavi or JDSU.
Strong knowledge of Layer 0 , Layer 1 testing along with platform & optics test skills.
Experience with Datapath, model-driven telemetry, and network programmability.
Familiarity with scale and performance characterization.
Expectations
The successful candidate will operate as an experienced individual contributor who can independently own a significant routing or BNG feature area, develop production-quality automation, lead complex technical investigations, identify product and test risks, and provide evidence-based release recommendations.
The engineer is also expected to influence test strategy, improve engineering practices, mentor junior team members, and use AI-assisted tools responsibly while maintaining security, accuracy, and engineering accountability.
