- 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.
- Experience testing DeFi, tokenization, NFT, staking, or other blockchain-based products.
- Understanding of blockchain transaction flows and on-chain data validation.
- Experience working in startups or product-focused technology companies.
