About the Company

GSR is crypto's capital markets partner, helping founders and institutions scale with confidence. With over a decade of specialized expertise, we deliver institutional-grade market making, OTC trading, and strategic venture capital to support growth at every stage.

Our value goes beyond execution. We provide access to liquidity, real-time market intelligence, and strategic guidance shaped by years operating at the center of global crypto markets. We bridge the gap between traditional finance and digital assets, connecting teams with the capital, market access, and insights they need to build what's next.

About the Role

Every microsecond in this role carries weight. You'll be building the low latency infrastructure that connects GSR's trading systems to crypto spot and derivatives markets, and the code you ship has a direct line to trading P&L.

You'll design and build core components of our trading platform in Rust, working across market data distribution, order placement, and trade and balance management. This is hands-on development on production-critical systems, sitting within a multiregional team of five, working closely with Trading, Quant and Engineering to get solutions into production fast.

You'll also shape how we organise and expose our data: cataloguing, tracing provenance, and building the APIs and services that let users query analytics data themselves rather than wait on you.
