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.
