At Gravity Team, a quantitative proprietary trading firm, we are on a mission to balance the supply and demand across crypto markets around the world. Join our community of innovators, problem solvers and owners who apply scientific discovery techniques to make crypto markets a better place for everyone.
We’re building a proprietary OTC trading platform from scratch—an internal desk mini-exchange for high-value, high-frequency trades executed with institutional precision.
Rust will power the initial system, prioritizing robustness, integration, automation, performance reliability, and uptime.
Over time, it will evolve into a full internal exchange with advanced routing, capital optimization, and execution logic.
This is a top engineering focus this year because it directly affects trading revenue and risk exposure.
