Job description

We're hiring for one of the most established HFT prop firms in the US, for its largest and longest-running trading desk in New York.

The team is flat and led by engineers. There's no split between the people who build the systems and the people who find the trades. They want strong C++ developers who want to do research and trading, not just infrastructure.

• Research and develop high-frequency strategies in futures and equities
• Take ideas from research all the way to live trading, alongside the traders on the desk

What they're looking for

• Excellent modern C++, ideally in a low-latency or HFT setting
• Experience at a prop, HFT or market-making firm, or a strong engineer at a top tech firm who wants to move into trading
• Real interest in research and markets, not only engineering
• Open to all levels, including very senior hires
• Based in New York or willing to relocate

Why it's worth a look

• The firm's most successful desk, with a long track record
• A genuine hybrid role where you write the code and share in the trading
• Strong base and a bonus tied to desk performance
