Key responsibilities

• Quality strategy & process: Define and evolve QA standards, release criteria, and quality metrics tailored to a trading platform. Establish best practices for validating execution accuracy, pricing, and API reliability.
• Automation (E2E-first approach):Design, build, and maintain a scalable end-to-end automation framework for the web app, covering critical user journeys.
• API testing & validation:Develop comprehensive automated tests for backend services and APIs. Ensure consistency between API responses and frontend behavior.
• Trading logic validation:Validate correctness of execution paths, price impact, and fee calculations across different trading pairs and liquidity sources.
• Performance & reliability:Drive API-level load and stress testing for high-throughput scenarios. Validate system behavior under peak traffic and degraded conditions (timeouts, partial failures, node issues).
• Test data & environment strategy:Design reliable test environments and datasets (mocked or real blockchain interactions), ensuring repeatability of E2E and API tests.
• Cross-team collaboration & leadership:Work closely with Engineering and Product to define testable acceptance criteria. Take ownership of QA processes, drive automation adoption, and set quality standards across the team.
