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.

• 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.
