My client, a quantitative proprietary trading firm, is on a mission to bring greater efficiency and liquidity to crypto markets by balancing supply and demand across global exchanges.
They are building a world-class team of technologists, problem solvers, and innovators who apply scientific and engineering principles to make crypto markets more stable, transparent, and accessible.
About the Role
My client is looking for a Senior Backend Engineer to join their core engineering team. You’ll play a key role in developing a proprietary Over-The-Counter (OTC) trading platform that facilitates large, off-exchange trades with institutional counterparties. This system is being built from scratch and integrates capital routing, trading logic, and exchange connectivity into a high-performance, unified infrastructure.
You’ll focus on backend development in Rust, working closely with engineers, traders, and product teams to design scalable, reliable systems that align with real-world business needs.

-
Contribute to other areas such as capital allocation logic, payment systems, and data processing pipelines.

Proven ability to build and maintain complex systems (e.g., deep tech, algorithmic platforms, trading systems).
-
Strong production-level experience with Rust or other compiled languages.
-
Solid understanding of core programming concepts and backend architecture.
