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.
