• Experience configuring and troubleshooting 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.
• 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, troubleshooting, communication, and cross-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
• 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 analyzers (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

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.
• 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.
