• Lead the integration of AI/LLM technologies into testing strategy—from test generation and autonomous flakiness management to coverage gap detection, and beyond as the technology evolves
• Partner with engineering leadership to align testing strategies with product and platform roadmaps.
• Establish and enforce testing standards, quality metrics, and quality gates across the SDLC —  automated in CI/CD so quality is the path of least resistance.
• Build visibility and trust in quality signals through unified observability — dashboards, metrics, and alerting that provide actionable insight into product reliability and drive accountability.
• Design systems, tooling, and processes that empower developers to easily create, run, and maintain high-quality automated tests.
• Influence and mentor engineers to adopt shift-left testing, testability-focused design, and quality-first development practices.

• Deep understanding of CI/CD pipelines, distributed systems, and cloud-based test environments.
• Experience designing or architecting testing frameworks and developer tools that scale across large engineering organizations.
• Strong expertise in end-to-end testing frameworks (e.g., Playwright, Cypress, Detox) and best practices in automation architecture.
• Experience with API testing, performance testing, and security testing methodologies.
• Knowledge of containerization technologies (Docker, Kubernetes) and their application to automated testing.
• Strong conviction that AI will fundamentally transform software testing, and the drive to lead that transformation — staying current with emerging AI capabilities and proactively identifying where they can accelerate quality.
