About The Position

Mesh is seeking a QA Automation Engineer to own the quality engineering function end-to-end. This role involves designing automation frameworks, setting standards, and integrating quality into the development lifecycle. The engineer will work closely with development, product, and design teams to deliver reliable Web3 experiences. Mesh is a global company with headquarters in San Francisco, California, and this role will collaborate with teams 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.
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.

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 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.
