• Integrate automated tests into CI/CD pipelines to support frequent, reliable deployments.
• Mentor and guide mid- and senior-level QA engineers, setting best practices and driving a culture of quality-first development.
• Evaluate and introduce new tools, libraries, and frameworks to improve test coverage, performance, and developer experience.
• Participate in architectural discussions to ensure testability and reliability are baked into software designs from the start.
• Analyze test results, track quality metrics, and communicate risk and coverage to stakeholders.

Qualifications

• 4+ years of hands-on experience with Cypress for UI and end-to-end automation testing.
• Expert-level proficiency in TypeScript, JavaScript and Python
• Proven experience testing AI-powered or machine learning applications, including AI model validation techniques.
• Strong understanding of AWS services (e.g., Lambda, S3, SQS, CloudWatch, ECS/EKS) and how to validate applications deployed in cloud environments.
• Experience with threaded/multi-agent AI tools and how they impact test design and validation.
• Familiarity with version control (Git), containerization (Docker), and CI/CD pipelines (e.g., GitHub Actions, Jenkins, or CircleCI).
• Strong communication, leadership, and mentoring skills.

Preferred Qualifications

• Knowledge of AI model evaluation, model versioning, and monitoring tools (e.g., SageMaker, MLflow, LangChain, Vector Databases).
• Experience testing APIs, microservices, and event-driven architectures.
• Background in testing non-deterministic systems, including applying statistical or heuristic testing approaches.
• Contributions to open-source testing or AI tools are a plus.
