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. This matters most to the hiring team, so tell us what draws you to 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. If you've built something you're proud of, we'd love to see it.

Tech Stack

Rust, Tokio, Distributed Systems, Blockchain, REST APIs, WebSocket APIs, Docker

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

Our client can support TN visas and H-1B transfers, including candidates currently on OPT moving to H-1B. They can't support H-1B transfers for candidates in year 3 or year 6 of their H-1B.
