Contribute to continuous improvements in reliability, performance, and security.

What We're Looking For

Experience testing production software products in a QA or Software Testing role.

Experience working on blockchain, cryptocurrency, Web3, or decentralized application projects.

Strong understanding of software testing methodologies and quality assurance practices.

Experience testing APIs, web applications, and backend services.

Ability to investigate issues, analyze root causes, and communicate findings clearly.

Strong attention to detail and a user-focused mindset.

Comfortable working in a fast-paced, collaborative environment.

Nice to Have

Experience with test automation frameworks and automated testing tools.

Familiarity with Ethereum, EVM-compatible networks, wallets, and smart contract interactions.

Understanding of blockchain transaction flows and on-chain data validation.

Experience working in startups or product-focused technology companies.
