Frontend Engineer

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.
