Job description

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.

What You’ll Do

• 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 test detection and self-healing frameworks
• Anomaly detection in logs, metrics, and network traffic

Additional Nice to Have

• Familiarity with observability stacks (logs, metrics, tracing) and applying them to quality engineering.
• Experience with Kubernetes, Docker, and cloud-native test environments, including ephemeral and scalable test infrastructure.
• Good understanding of networking protocols and systems (TCP/UDP, BGP, ISIS, HTTP/S, multicast, switching/routing).
• Deep expertise in software architecture and design patterns (OOP, microservices architecture) applied to test systems.
• Experience with data engineering concepts (test data pipelines, telemetry ingestion) and exposure to MLOps workflows is a plus.
