XRAYS TRADING Tech Stack

Trading-desk software and infrastructure for financial markets

Financial Services Paris, Île-de-France 11–50 employees Founded 2004 Privately Held

XRAYS TRADING builds execution and risk infrastructure for trading floors — FX dealing, index generation, portfolio management, and algorithmic execution. The tech stack (Python, C++, C#, .NET Core, SQL Server, Azure, FIX protocol) is finance-grade and latency-sensitive; active pain points around low-latency performance, risk modeling, and security vulnerability detection signal a company focused on the hard systems problems that break trading operations. Engineering dominates the headcount (12 of 17 open roles), with accelerating hiring momentum concentrated in mid and senior IC roles — typical of a growing boutique firm scaling delivery capacity.
