About the company
Our client is a seed-stage crypto and fintech startup in San Francisco building the backend infrastructure for a high-performance, real-time trading platform. It has raised more than $15M, the team is about ten people, and the founder has spent more than a decade in crypto. The product processes live market data and coordinates trading across venues at scale, so the backend is the core of the business rather than a supporting layer.
The role
You would join as a backend engineer writing production Rust for the systems that trading, settlement and risk run on. The work is asynchronous, performance-driven and close to the market: risk and liquidation engines, state machines, live market data and low-latency APIs. The team works together in person five days a week in a high-bandwidth, collaborative setting. It suits an early-career engineer with real Rust experience who wants harder problems and a genuine interest in trading, rather than a quieter job.
What you'll do
- Build and maintain risk and liquidation engines that manage risk and improve capital efficiency in volatile markets
- Design and implement the blockchain state machines that power trading, settlement and risk operations
- Develop services that keep state consistent across asynchronous processes using voting, consensus and coordination mechanisms
- Process live market data and coordinate actions across trading venues, managing WebSocket streams and time-sensitive workflows
- Build high-performance REST and WebSocket APIs that power the trading interface with millisecond-level response times
Nice to have
- Experience in fintech, trading or blockchain
- Low-latency or trading-systems experience, for example at a trading firm or on large-scale network infrastructure
- Personal side projects, especially in Rust or C
Tech stack
Rust (async, with Tokio), C/C++, REST and WebSocket APIs, Docker, and relational, time-series and key-value databases.
