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.
