QA Engineer (Manual + Automation) - Web3 / Blockchain

About the Project: We are looking for a QA Engineer to join a team building a real-world asset (RWA) tokenization platform that connects issuers and investors. The platform lets users create, issue, mint, burn and transfer tokens using the ERC-3643 standard on Ethereum. The product sits at the intersection of digital assets and traditional finance and operates in a highly regulated space, so compliance and security are top priorities. It includes role-based access control, approval quorums, KYC/KYB identity verification, AML transaction and wallet monitoring, and self-custodial wallet integration, with institutional non-custodial wallets planned next. The testnet is already live, and the team is preparing a restricted mainnet launch in mid-November, followed by a full launch next year. Responsibilities: - Own end-to-end testing of the platform, from requirements analysis to release validation; - Test core blockchain flows: token issuance, minting, burning and transfers, wallet connections and on-chain transactions on testnet and mainnet; - Test compliance-related functionality: KYC/KYB onboarding, role-based access, approval flows and AML integrations; - Design and maintain test documentation (test cases, checklists, test plans); - Develop and maintain automated UI and API tests with Playwright + TypeScript; - Perform regression, smoke, integration and exploratory testing; - Identify, document and track bugs in Jira or similar tools; - Collaborate closely with developers, product managers and the client team; - Support release processes, including the testnet-to-mainnet launch and post-release verification. Requirements: - 4+ years of professional experience in QA; - Commercial experience testing Web3 / blockchain products (must have): crypto wallets, tokens, transactions, Ethereum or EVM testnets; - Commercial experience with test automation using Playwright + TypeScript (Cypress is acceptable); - Strong manual testing skills for web applications; - Experience with API testing (Postman, Swagger); - Basic SQL knowledge for data validation; - Understanding of client-server architecture and SDLC; - Experience working in Agile/Scrum teams; - English: Intermediate or higher (written and spoken). Nice to have: - Experience with ERC-20 / ERC-3643 tokens or smart contract testing (Hardhat, ethers.js); - Experience testing KYC/KYB, AML or other compliance flows; - Fintech or financial services background; - Mobile testing and mobile automation (Appium or similar).
