QA Engineer

Own product quality across web, mobile, and blockchain-integrated applications. You’ll design risk-focused test coverage, exercise end-to-end user journeys, and automate important checks in partnership with engineering teams before releases.

• Create test plans, test cases, and regression suites for blockchain applications.
• Perform functional, integration, API, and exploratory testing across product workflows.
• Validate smart contract interactions, on-chain activity, and blockchain integrations.
• Test wallet connections, authentication, transaction signing, and transaction lifecycle behavior.
• Cover edge cases such as failed transactions, network problems, gas issues, and wallet rejection; verify token transfers, ownership, and event processing.
• Automate high-value UI, API, and blockchain integration checks, then investigate defects and confirm fixes.

• At least three years of QA experience on software products, including hands-on testing of blockchain or Web3 applications.
• Understanding of blockchain transactions, smart contract interactions, and Ethereum or EVM-compatible networks.
• Familiarity with wallet connectivity, transaction signing, and on-chain events.
• Strong test design, regression testing, bug reporting, API testing, and browser automation skills.
• Ability to assess complex multi-step workflows and distributed systems through functional, integration, and end-to-end testing.
• Strong analytical skills, attention to detail, and clear communication with product and engineering teams.

• Experience with Playwright, Cypress, or Selenium.
• Solidity contract testing or familiarity with Hardhat, Foundry, or other blockchain testing frameworks.

• Remote role open across global time zones, with full-time or part-time arrangements.
• Collaborate with blockchain, backend, frontend, and product teams on production releases.
