Job summary

Capital Markets Trading in London is seeking a versatile Software Engineer for Trading Analytics to join our small, global technology team. This role covers pricing and risk analytics, data infrastructure, and back-office systems, requiring broad scope rather than deep specialization.

You will build data pipelines and analytics that convert models into numbers used by traders—vol surfaces, PnL, Greeks—and develop high-performance distributed systems.

• An AI-native approach: you use modern AI tools thoughtfully to explore ideas, reason through problems, and work more effectively.

Responsibilities

• Develop the data pipelines and analytics that turn pricing and risk models into the numbers traders rely on, including volatility surfaces, PnL, and Greeks.
• Build distributed, high-performance systems using industry-standard open-source technologies.
