Trading Desk

The Firm

XTX Markets is a leading algorithmic trading firm. We build models that forecast prices for more than 53,000 financial instruments across equities, fixed income, currencies, commodities and crypto. Those forecasts are used to trade on exchanges and other venues and provide liquidity to clients worldwide. The firm trades over $250bn a day across 35 countries and has over 300 employees in London, Singapore, New York, Paris, Bristol, Mumbai, Yerevan and Kajaani.

XTX is a technology business. Trading is driven by research, large-scale computation and careful engineering. Over the last decade, our trading models have evolved from the econometric methods that gave the firm its name, through trees and neural networks, to modern deep learning architectures. We expect that evolution to continue.

XTX has an unusually large research platform for a trading firm, with well over 25,000 GPUs and more than 1 exabyte of usable storage, alongside further compute being built in Finland. The aim is simple: good ideas and decisions should not be bottlenecked by data, infrastructure or compute.

At XTX Markets, technology is our business. We are a diverse organisation that attracts outstanding talent from across all industry backgrounds. Our people collaborate across the business, working openly and respectfully with each other, our clients and the market. Our culture is non-hierarchical, everyone is valued, and we strive for excellence in everything we do.

The Trading Desk is the real-time control layer for XTX’s automated trading businesses, working with quantitative research, trading technology, risk, operations, exchanges and clients to keep the engine operating reliably 24/7.

As a Trading Desk Analyst, you will take operational ownership of this layer. The role requires deep systems thinking rather than software engineering, and a strong grasp of the principles, inputs, outputs and failure modes of our automated trading infrastructure.

In this role, you will use internal tools, dashboards and automated workflows to monitor, diagnose and optimize real-time engine performance. When anomalies arise, you will interrogate the data quickly and execute or coordinate interventions to safeguard firm, client and counterparty capital. You will translate complex operational signals into high-impact decisions that prevent losses and drive measurable value.

This role is for a highly curious, analytical thinker who thrives under pressure and wants direct responsibility for a multi-billion dollar trading engine. We are looking for someone with an ownership mindset on every shift, who proactively prevents losses and improves system outcomes.

As a member of the desk, your responsibilities include:

• Real-Time Supervision: Own real-time supervision of automated trading strategies and related operations, focused on the markets most relevant to XTX.

• System Intuition & Vigilance: Develop a strong understanding of expected engine behaviour. Maintain a healthy, proactive scepticism of automated outputs, hunting for irregularities and taking timely action before issues escalate.

• Metrics & Analytics: Use trading metrics, dashboards, alerts and data workflows to understand performance, liquidity, execution quality, risk, positions and operational health.

• Incident Response: Respond calmly and decisively to market events, venue issues, client flow, risk-limit changes and internal anomalies, escalating when required.

• Incident Ownership: Own system alerts, anomalies and operational breaks from detection through resolution, ensuring nothing falls through the cracks.

• Feedback Loop: Provide precise, evidence-based feedback to quantitative research and trading technology teams, turning live-market observations into useful
