Senior QA Automation Engineer
mesh • Europe - Remote
Posted: April 24, 2026
Job Description
Overview
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.
What You'll Do
- 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
Who You Are
Automation Expertise
- 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.)
Web3 Knowledge
- 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
AI-First Mindset
- 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
The Right Mentality
- 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 Have
- 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
