LayerZero The Future is Omnichain. Founded in 2021, LayerZero’s vision is to create a community of cross-chain developers, building dApps that are no longer constrained by individual blockchain capabilities. With LayerZero's simple, generic messaging protocol, builders will develop cross-chain dApps designed to unify the power of individual blockchains. We are funded by the best investors in the world including: a16z, Sequoia, PayPal, Binance Ventures, Coinbase Ventures, Uniswap Labs, Circle Ventures, Delphi Digital, and many more. ABOUT THE ROLE We're hiring a QA Engineer to take full ownership of testing across our CLI tools, frontends, developer interfaces, and product surfaces. Engineers at LayerZero write their own tests, but this role exists to build dedicated QA coverage where it's missing, improve test reliability, and reduce risk in production. You’ll work across the stack to implement efficient, high-signal manual and automated testing processes that integrate cleanly into our development flow. WHAT YOU'LL DO
Build and maintain test coverage for CLI, frontend apps, and devtools Write and maintain test automation using frameworks like Playwright, Cypress, or similar Create and document reproducible test cases for product workflows and edge cases Identify gaps in existing test coverage and implement targeted solutions Collaborate with engineers to improve code testability and CI integration Investigate and verify bugs prior to release; ensure test coverage for all fixes Monitor test outcomes and reliability across environments You have excellent problem-solving skills and attention to detail.
ABOUT YOU
Bachelor's degree in Computer Science or related field, or equivalent practical experience. 3+ years experience in QA, test engineering, or software testing roles Experience testing web frontends (React/Next.js), APIs, and CLI-based applications Comfortable working in TypeScript codebases and debugging frontend/backend interactions Familiar with automated test frameworks and integrating them into CI pipelines Detail-oriented and structured, you able to turn requirements into comprehensive test coverage Previous experience with blockchain technologies, smart contracts, and decentralized finance is a strong plus.

What does a React developer in web3 do?
A React developer in the context of web3 is a developer who is using the React JavaScript library to build user interfaces for decentralized applications (dApps) that run on the Ethereum blockchain
These dApps often use smart contracts to facilitate transactions and other interactions on the Ethereum network
Overall, the role of a React developer in web3 involves using your skills in React development to help build cutting-edge decentralized applications that leverage the power of the Ethereum blockchain
As a React developer in web3, some of your responsibilities might include:
- Integrating the dApp with the Ethereum blockchain. This might involve using tools like web3.js and Ethers.js to connect to the Ethereum network and interact with smart contracts.
- Building the user interface for a dApp using React. This could involve creating components for the various elements of the dApp, such as buttons, forms, and other input elements.
- Implementing features that are specific to decentralized applications, such as handling cryptocurrency transactions and displaying data from the blockchain in a user-friendly way.
- Collaborating with other members of the development team, such as blockchain engineers and designers, to ensure that the dApp functions properly and meets the needs of the end users.
