Backend Software Engineer (Rust)

About the Opportunity

We're partnering with a fast-growing, VC-backed trading technology company in San Francisco to hire 3–5 Backend Software Engineers with production Rust experience. They're building the backend infrastructure for a real-time trading platform, systems where milliseconds matter, markets move fast, and getting it right has real consequences.

This is a chance to work on hard problems: risk engines that hold up in volatile markets, blockchain state machines that power trading and settlement, and distributed systems that stay consistent under pressure. You'll join a small, high-bandwidth team that works together in person, five days a week, and moves quickly.

What You'll Be Doing

• Building and maintaining risk and liquidation engines that manage exposure and improve capital efficiency when markets turn volatile.
• Designing and implementing the blockchain state machines behind trading, settlement and risk operations.
• Developing services that keep state consistent across asynchronous processes, using voting, consensus and coordination mechanisms.
• Processing live market data and coordinating actions across trading venues, managing WebSocket streams and time-sensitive workflows.
• Building high-performance REST and WebSocket APIs that power the trading interface with millisecond-level response times.

What You'll Bring

• 2–4 years of experience as a backend software engineer, with in-depth, production-level Rust experience.
• A genuine, demonstrable interest in trading or financial markets.
• Experience building backend services for real-time, high-throughput systems.
• Strong command of asynchronous programming (e.g. Tokio).
• Proficiency with a range of databases, including relational, time-series and key-value.
• Startup experience, ideally in a VC-backed environment.
• A performance-driven mindset and a preference for working closely with your team in person.

Nice to Have

• Experience in FinTech, trading or blockchain.
• Low-latency or trading-systems experience, whether at a trading firm or on Cloudflare-style infrastructure.
• Personal side projects, especially in Rust or C.

The Package

Base salary of $185,000–$300,000, depending on experience. Competitive equity. Full-time, on-site role, 5 days a week in the San Francisco office. Visa Sponsorship available.
