Fullstack.Trade
We're looking for a Backend Systems 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 risk and liquidation engines that manage risk and capital efficiency in volatile markets.
- Design blockchain state machines powering trading, settlement, and risk operations.
- Build consensus and coordination services that keep state consistent across async processes.
- Process live market data: WebSocket streams and time-sensitive workflows across trading venues.
- Ship high-performance REST and WebSocket APIs with millisecond-level response times.
Requirements
- 2–4 years of backend experience with production Rust.
- Real-time, high-throughput backend services (systems-level, not pipeline work).
- Async programming with Tokio.
- Relational, time-series, and key-value databases.
- Startup or VC-backed company experience.
- Active public GitHub with Rust or C projects outside of work.
- Genuine passion for trading: you actively trade perps or prediction markets, run trading bots, or build on-chain.
- US work authorization: TN and H1B transfers supported (not in year 3 or 6), no OPT/F1.
- On-site 5 days/week in NYC or SF.
Stack
- Rust, Tokio, distributed systems, blockchain, REST APIs, WebSockets,
