Staff Frontend Engineer

Our client is a high-growth fintech and Web3 technology company currently serving over two million users. Backed by top-tier venture capital firms, the organization has raised substantial Series B funding to scale its platform, expand product offerings, and maintain high engineering standards while accelerating development velocity.

In this role, the engineer will drive critical frontend initiatives—including the rollout of new order types, support for additional asset classes (such as perpetuals and prediction markets), and the expansion of key social features.

The ideal candidate possesses deep mastery of React, operates effectively with a high degree of autonomy, and thrives in a fast-paced, in-person environment. While focused on frontend architecture, engineers are empowered to contribute across the stack whenever beneficial.

• Application Ownership: Lead and architect frontend development across primary platforms, including a mobile application (built with Expo) and a web application (built with React Router and Vite).
• Feature Development: Design, build, and deploy high-impact features such as advanced order types, new financial asset integrations, and engaging social functionalities.
