About The Position

We are seeking a QA Automation Engineer to own the quality engineering function end-to-end. In this role, you will be responsible for designing automation frameworks, setting standards, and embedding quality into every step of the development lifecycle. As a core member of the team, you will not be a seat at the back of the sprint, but will work closely with engineers, product, and design to ship reliable, production-grade Web3 experiences. Mesh is a global company with headquarters in San Francisco, California USA. This candidate will work closely with the Engineering and Product teams spread across North America, Europe and India.

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
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

Nice To Haves

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 testnets or mocking Web3 providers is a strong plus
Familiarity with blockchain explorers, event indexing, or subgraph testing

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
