Job Summary

Job Summary

We are looking for a highly motivated AI-savvy Principal Software Quality Assurance Engineer to join our Digital Web QA team. As a Principal SQA Engineer, you will be responsible for creating and implementing a strategy for quality coordination and transforming how we test and validate as well as suggesting solutions to identified quality problems. All this in a fast paced, agile-based process of development, test and release. In this role, you will design and implement autonomous QA workflows that leverage AI to achieve unprecedented test coverage, efficiency, and defect detection. You will take ownership of quality outcomes, mentor teams, and drive innovation in how we approach testing at scale.

Key Responsibilities

• Design and implement autonomous scalable End-to-End (E2E) QA workflows using AI agents and LLM-based frameworks to achieve continuous, intelligent test execution across multiple services.

• Develop AI-augmented test infrastructure enabling scalable, context-aware testing that reflects real-world deployment scenarios —specifically integrating self-healing test suites, AI-driven test case generation, and Visual AI regression tools.

• Build AI-powered test generation systems that automatically create comprehensive test suites from requirements, specifications, and production telemetry.

• Participate in system design to ensure quality, observability, and testability are built-in throughout the feature development lifecycle.

• Provide technical leadership in browser security, cloud orchestration, distributed systems, and AI-assisted quality engineering across multi-team quality initiatives.

• Mentor junior and mid-level engineers on AI/ML testing techniques, prompt engineering, and modern quality practices; lead adoption of new testing methodologies and measure impact.

• Collaborate with Development, SRE, Product Management, and Technical Marketing to align quality strategy with business outcomes and establish quality standards.

• Enhance test strategies, automation, and build infrastructure with feedback and analysis from real-world customer deployments.

• Stay current with AI/ML advancements and translate them into practical testing innovations like agentic workflows, multimodal testing, and AI-powered observability.

• Execute system tests including functional and E2E on sanity, regression, pre-production, and post-production phases in a tight release schedule

• Track and report the outcome of test executions and all information needed to support ongoing measurements and reporting on risks, defects, tests, and coverage.

• Conduct deep-dive root cause analysis on complex, multi-system bugs and collaborate directly with developers to implement corrective actions.

• Establish the overarching AI strategy for new features and major website redesigns in a fast-paced, Agile/Scrum environment.

• Conduct system functional testing to ensure system quality, reliability, capacity, and scalability.

• Compare and analyze system behavior vs. expected results/KPIs based on business and technical requirements.
