You will own the trading core, including order and execution management, exchange integrations and market data pipelines, which risk, the ledger and our client apps all build on.

• Deep experience with exchange or broker APIs (REST, WebSocket, FIX), order lifecycles and market data
• Strong command of a systems or backend language used in production trading, such as C++, Rust, Java or Go
• Solid distributed systems fundamentals: concurrency, idempotency, back-pressure, failover and consistency
• Experience designing for high message rates (tens of thousands per second and up) at millisecond latency
• A track record of owning a production system end to end, including on-call for a 24/7 market
• Clear written and spoken English
