Software Engineer, Backend Systems - Crypto Trading

We are seeking a hands-on backend systems engineer with meaningful production Rust experience, strong asynchronous programming skills, and a genuine interest in trading and financial markets.

You will build performance-critical infrastructure involving live market data, risk management, blockchain execution, and low-latency trading workflows. This position suits an engineer who enjoys technical ownership, close collaboration, and the pace of a small startup.

Responsibilities

• Build and maintain risk and liquidation engines that manage exposure and improve capital efficiency.
• Design and implement blockchain state machines supporting trading, settlement, and risk operations.
• Develop services that maintain consistent state across asynchronous processes using coordination and consensus mechanisms.
• Process live market data and coordinate time-sensitive actions across trading venues.
• Build and maintain real-time workflows and WebSocket streams.
• Develop high-performance REST and WebSocket APIs with millisecond-level response times.
• Identify and resolve performance bottlenecks in high-throughput backend systems.
• Collaborate with founders and senior engineers on architecture, implementation, and system reliability.

• Approximately 2-4 years of relevant backend software engineering experience.
• Meaningful, hands-on experience building or maintaining production systems in Rust.
• Experience with asynchronous programming using Tokio or comparable Rust-based asynchronous systems.
• Experience developing real-time, high-throughput backend services.
• Low-latency or trading-systems experience.
• Proficiency with multiple database types, such as relational, time-series, and key-value databases.
• Meaningful startup experience.
• Experience in fintech, crypto, trading, high-frequency trading, or blockchain.
• Demonstrable interest in trading and financial markets.
• Meaningful personal engineering projects, particularly in Rust or C.
• Strong backend and systems-engineering fundamentals.
• Comfort working in a fast-moving, collaborative startup environment.
• Ability to work onsite in New York City or San Francisco five days per week.
• U.S. citizenship or Green Card status, with no current or future visa sponsorship requirement.

Production Rust experience is essential. Experience with C, C++, or another backend language does not replace this requirement.

Additional Experience Valued

• Distributed systems and concurrent programming.
• REST and WebSocket API development.
• Live data streams and time-sensitive processing.
• Docker.
