The Role

We’re expanding our frontend engineering team in Latin America to build next-generation interfaces for the Nexus ecosystem. As a Frontend Engineer, you’ll design and deliver intuitive, high-performance user experiences for our DEX, developer tools, and verifiable finance applications — making complex financial systems transparent and accessible.

You’ll collaborate with product, backend, and protocol teams in San Francisco while contributing remotely from Argentina or Mexico. We move fast, ship often, and expect engineers to take full ownership of their work.

What You’ll Do

  • Build responsive, performant web applications in React and TypeScript.

  • Create interfaces for our enshrined DEX, analytics dashboards, and developer tooling.

  • Integrate APIs and blockchain services to surface verifiable on-chain data.

  • Implement interactive visualizations for trades, liquidity, and transaction flows.

  • Collaborate closely with design to deliver polished, intuitive user experiences.

  • Iterate quickly based on real-world feedback from traders and developers.

What We’re Looking For

  • Strong experience building production React/TypeScript applications.

  • Solid understanding of web performance, state management, and component architecture.

  • Comfort integrating backend APIs and blockchain or financial data sources.

  • A sharp eye for UX, interaction design, and visual clarity.

  • Excellent communication skills in Business English (spoken & written).

Bonus Points For

  • Experience with financial applications, trading interfaces, or data visualization.

  • Familiarity with Node.js, Rust, or WebAssembly.

  • Experience in Web3 or blockchain-based systems.

  • Background at high-impact startups or fast-paced environments.

Why Join Us

  • Build the interfaces powering the next generation of verifiable financial systems.

  • Collaborate with world-class engineers, designers, and researchers across continents.

  • Help define how users experience an on-chain DEX embedded in a Layer 1.

  • Thrive in a fast-paced, ambitious environment where ownership drives growth.

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.
