## Description

Senior Java Developer, Execution Algos and Smart Order Router (Low Latency)
London, hybrid

A fast-growing electronic trading firm is building the next generation of its execution technology in London and wants a senior Java engineer to own the EMS and Smart Order Router (SOR) end to end.

This is a greenfield build. You will design and develop a low-latency, high-throughput SOR and execution algo suite from the ground up, working directly with the trading desk across FX and digital asset markets. Real ownership, not maintaining someone else's legacy stack.

What you will be doing

 * Design and build a low-latency, high-throughput EMS and Smart Order Router in Java
 * Develop execution algorithms such as VWAP, TWAP, POV, liquidity seeking and crossing
 * Build intelligent routing logic based on execution quality, liquidity, latency and cost
 * Work with real-time market data, tick data and multicast feeds
 * Tune for performance, fill ratio and latency under live trading conditions
 * Partner with traders and quants to refine routing logic and build new capabilities
