QA Engineer

Role Overview

• Perform manual, exploratory, regression, integration, and end-to-end testing across multiple products and systems.
• Design, build, and maintain a UI automation test suite and quality tooling using Typescript and Playwright. Integrate wallet extensions such as MetaMask/Keplr into the test suite.
• Validate functionality across web applications, APIs, backend services, blockchain infrastructure, and protocol-level features.
• Investigate issues across frontend, backend, infrastructure, and distributed systems.
• Analyze logs, metrics, network traffic, and system behavior to identify root causes and quality risks.
• Collaborate with Product, Engineering, DevOps, and other stakeholders throughout the development lifecycle.
• Contribute to release validation, test strategy, automation initiatives, and continuous improvement efforts.
• Leverage AI-powered tools and workflows to accelerate testing, automation, investigation, and overall quality engineering productivity.
• Support new products, features, and initiatives as business priorities evolve.
• Assist with production investigations, incident analysis, and post-release validation when needed.
• Proactively identify quality gaps, process inefficiencies, and opportunities to improve product reliability and testing coverage.
