ABOUT YOU
We are looking for a Senior QA Engineer with strong Web3 experience to join our engineering team. You are meticulous, technically sharp, and deeply curious about decentralized technologies. You understand the nuances of blockchain interactions, wallet integrations, smart contract behavior, and hybrid on-chain/off-chain systems.
You thrive in fast-paced, agile environments and bring a proactive approach to quality-anticipating risks, validating distributed systems, and ensuring seamless user experiences across Web3-enabled features. You are confident in manual testing, comfortable with API-level validation, and eager to integrate AI-driven testing tools to improve coverage, speed, and defect detection.
If you're excited to shape quality practices for blockchain-enabled products and help define how Web3 experiences should feel for millions of users, we'd love to meet you.
