Principal AI & Automation Engineer

About the role

We're seeking a Principal AI & Automation Engineer, to lead the evolution of our next-generation quality engineering platform. This role is ideal for a highly experienced engineer who can architect intelligent, self-adaptive test automation frameworks for cloud-native, microservices-based broadband systems. You will combine deep automation expertise, modern software architecture, and AI/ML-driven testing approaches to transform complex system requirements into scalable, resilient, and insight-driven quality solutions. As a technical leader, you will drive autonomous testing strategies , enabling faster releases, higher reliability, and continuous quality validation across DOCSIS and PON features on vCMTS ecosystem.

Responsibilities

• Architect and build scalable, modular, and AI-augmented test automation frameworks supporting functional, integration, and performance testing.
• Design self-healing and adaptive test systems using AI/ML techniques (e.g., anomaly detection, flaky test prediction, intelligent test selection).
• Implement shift-left and shift-right QA strategies , embedding quality across the entire SDLC and production monitoring pipelines.
• Develop data-driven and model-based testing approaches , leveraging telemetry, logs, and production data to improve test coverage and accuracy.
• Lead automation efforts for cloud-native, microservices-based DOCSIS/PON platforms , ensuring high availability and performance at scale.
• Collaborate with engineering, product, and QA teams to translate requirements into intelligent, reusable automation assets .
• Integrate QA deeply into DevOps/MLOps pipelines , enabling continuous testing, validation, and feedback loops.
• Drive Core Virtualization and network validation initiatives , applying advanced simulation, traffic modeling, and AI-assisted diagnostics.
• Build tools for predictive quality analytics , identifying risks and failure patterns before they impact production.
• Troubleshoot complex distributed systems using advanced observability, AI-assisted root cause analysis, and debugging techniques .
• Mentor engineers on modern QA practices, Python architecture, and AI-driven test automation strategies .
• Skills & Experience We're Looking For:
• Required :
• Strong track record of building enterprise-grade, extensible automation frameworks.
• Strong proficiency in Linux/Ubuntu environments, CLI tooling, and automation scripting (Python, Go, Shell scripting).
• Hands-on experience with traffic generation and network test tools (e.g., IXIA, ByteBlower) and simulation platforms.
• Ability to analyze packet captures, simulate network conditions, and validate end-to-end system performance at scale .
• Familiarity with observability stacks (logs, metrics, tracing) and applying them to quality engineering.
• Strong experience with CI/CD pipelines (Jenkins, GitLab CI) and version control (Git), with emphasis on continuous testing and quality gates .
• Experience integrating AI/ML into QA workflows , such as: Intelligent test case generation
• Test optimization and prioritization
• Flaky
