Frontend Engineer

About the role

We're looking for a Frontend Engineer to join Fullstack.

Fullstack Trade is building the only unified front-end trading app for retail crypto – perps, cross-chain spot, and prediction markets under one portfolio margin balance. No bridging, no fragmentation. Founded by Flood, creator of Insilico Terminal ($900B CEX volume, 90% market share), and Robin, operated a leading CEX and on-chain HFT firm. Launching Jan/Feb 2027.

You will

- Build full-featured web apps and reusable UI libraries that are fast, accessible, and scalable.

- Create high-performance interactive charts and real-time market data displays.

- Drive performance: sub-second load times, advanced caching, latency-sensitive UX.

- Own client-side architecture: REST and WebSocket integration, robust state management.

- Set up CI/CD: automated builds, previews, testing, and rollbacks.

Requirements

- Strong React, TypeScript, and JavaScript; frontend-first, not backend-leaning full-stack.

- Strong CSS and WAAPI experience.

- Experience building real-time or latency-sensitive interfaces (trading, gaming, or similar).

- Public, live deployed frontend work with polished visual quality.

- Active GitHub with recent commits.

- You actively trade crypto or perps and can name the venues and products you use.

- US work authorization (TN supported).

- On-site 5 days/week in SoHo, NYC.

Stack

- React, TypeScript, JavaScript, CSS, WAAPI, WebSockets, REST APIs, Jest, Vitest, Cypress, CI/CD.

Nice to have

- Frontend experience at a trading firm or exchange.

- No degree required: bootcamp and self-taught engineers with strong projects are welcome.

We offer

- Up to $300k/year salary + equity.

- Small, fully on-site team in SoHo, direct work with the founders.
