About Five Rings

Five Rings is a proprietary trading firm founded with a vision of combining strategy, innovation and technology to succeed in today’s global markets. With offices in New York, Boca Raton, London and Amsterdam, Five Rings trades in various domestic and international markets, both established and esoteric. Our team constantly seeks new opportunities, analyzes their risks and rewards, and creates strategies and tools to capitalize on them.

We have an open culture and encourage the flow of knowledge and ideas between all areas of the firm.

Interviews will begin in September 2026.

About the Role

Five Rings gives responsibility immediately and recognizes contributors rapidly. New hires work closely with senior software engineers, traders, and quants developing trading software in C++ on Linux.


Application development includes implementing trading strategies, connecting to exchanges, designing trader-facing interfaces, and translating mathematical models into software code – all within a distributed system that spans the globe. If you can write great software as part of a team, and are comfortable both learning from and becoming a mentor, you’re likely to thrive here.

Applicants are able to apply to multiple positions, but we strongly encourage you to only apply to your top choice.
