About the role

Key responsibilities & impact

Review functional specifications and technical design documents, providing meaningful feedback and using AI-assisted analysis to identify edge cases or logic gaps early in the SDLC.
Work closely with development teams to identify test cases for automation and leverage AI-powered IDEs (like Cursor or Augment) to rapidly prototype and scaffold new test suites.
Design, develop, and execute test cases against product features and backend systems.
Maintain and extend automation frameworks (Playwright/Locust) by utilizing LLMs for code refactoring, optimizing test scripts, and reducing flaky test patterns.
Contribute to your development team on best practices, processes, and problem-solving, including the ethical and effective use of AI tools in the QA workflow.
Develop automated test result reports and highlight any potential quality risks.
Identify, troubleshoot, and track bugs to resolution, using AI tools to assist in root cause analysis and log interpretation.
Be an advocate for automation: Partner with the engineering team to provide recommendations on how to decrease manual efforts through automated solutions and AI-driven test generation.
Experience designing evaluation frameworks for LLM-powered features, including prompt regression testing and behavioral drift detection.
Proactively leverage AI tools (e.g., Cursor, Claude, etc…) to accelerate test authoring, debugging, and maintenance of automation frameworks.
Use AI to diagnose failures, generate test scenarios, and improve coverage and efficiency.
Contribute to testing strategies for AI-powered features, including validation of LLM outputs, edge cases, and reliability.
Drive best practices for the ethical and effective use of AI tools within QA workflows and across the broader engineering team.
