Senior QA Automation Engineer

Mesh is a company focused on enabling consumers to transact with any asset, bridging the gap in crypto payments. They are seeking a Senior QA Automation Engineer to design and maintain automation frameworks, ensuring quality in the development lifecycle while collaborating with cross-functional teams.

Responsibilities:

• Architect, build, and maintain robust end-to-end test automation frameworks using tools like Playwright
• Design test strategies that cover the full stack: UI, API, smart contract interactions, and wallet flows
• Write and maintain tests for Web3-specific user journeys including wallet connection, transaction signing, contract interactions, and on-chain state verification
• Integrate automated test suites into CI/CD pipelines and own the health of those pipelines
• Leverage AI-powered development tools (Copilot, Cursor, Claude, etc.) to accelerate test authoring and framework development, and bring strong opinions on how to do this well
• Identify gaps in test coverage, prioritize ruthlessly, and drive continuous improvement
• Champion quality culture across the engineering org
• Stay ahead of the curve on new testing tools, frameworks, and Web3 ecosystem shifts

Requirements:

• 7+ years of experience in QA engineering with a strong focus on automation
• Deep hands-on experience with Playwright and/or Cypress; familiarity with others (WebdriverIO, Selenium, Puppeteer) is a plus
• Proficiency in at least one scripting/programming language (TypeScript, JavaScript, Python)
• Experience designing and scaling test frameworks from the ground up, not just maintaining existing ones
• Strong understanding of CI/CD practices and integrating tests into pipelines (GitHub Actions, CircleCI, etc.)
• Working knowledge of core Web3 concepts: wallets (MetaMask, WalletConnect), transaction signing, smart contracts, gas, RPC endpoints, and on-chain/off-chain interactions
• Experience testing dApps and writing tests that interact with or simulate blockchain state
• Familiarity with testnets or mocking Web3 providers is a strong plus
• Active, hands-on user of AI code generation and developer tools (e.g., GitHub Copilot, Cursor, Claude, ChatGPT)
• You have real opinions on where these tools shine and where they fall short - you've found the edges
• You use AI to move faster without sacrificing rigor, and you can teach others to do the same
• Self-starter who identifies problems and drives solutions without waiting to be asked
• Comfortable with ambiguity and able to operate effectively in a fast-paced, resource-constrained startup environment
• Curious by default, you read release notes, follow ecosystem developments, and enjoy going deep on new tools and technologies
• Clear communicator who can translate quality risk into terms the whole team understands
• Prior experience at an early-stage or growth-stage startup
• Exposure to performance, load, or security testing in Web3 contexts
• Contributions to open-source testing tools or frameworks
• Familiarity with blockchain explorers, event indexing, or subgraph testing
