About the Company

A seed-stage startup building a single trading front end for crypto, bringing perpetuals, cross-chain spot and prediction markets into one portfolio-margined experience. Its founders built widely used institutional trading tools.

The Role

The company is looking for a backend engineer with production Rust experience to help build the infrastructure behind its real-time trading platform: risk, settlement, market data and the APIs traders depend on. This role suits someone with strong asynchronous programming, solid systems knowledge and a performance-driven mindset who thrives in a collaborative, in-person environment.

What You Will Do

• Build and maintain risk and liquidation engines that improve capital efficiency in volatile markets.
• Design and implement the blockchain state machines that power trading, settlement and risk.
• Build services that keep state consistent across asynchronous processes using voting, consensus and coordination.
• Process live market data and coordinate actions across trading venues over WebSocket streams.
• Build high-performance REST and WebSocket APIs with millisecond-level response times.

What You Bring

• 2-4 years as a backend software engineer
• In-depth production experience with Rust
• Strong asynchronous programming (Tokio a plus) and distributed systems knowledge
• A performance-driven mindset for latency-sensitive, real-time systems
• Ability to work on-site in New York
