We are looking for a technically strong Senior Associate to join our Middle Office – Options team in London. You will be responsible for managing operational risk and ensuring front-to-back trade integrity in our growing options business, with a secondary focus on DeFi. The ideal candidate brings a junior quant mindset, is fluent in Python and SQL, and has hands-on experience automating risk and P&L processes, building scalable reconciliation frameworks, and working directly with options or structured derivatives.
This is a front-line technical operations role, bridging trading, risk, and engineering, and best suited for someone who thrives in high-velocity trading environments and enjoys solving problems with data, code, and process design.

• Build and maintain automated reconciliation tools, integrating data across multiple venues, clearing brokers, and internal systems for trade matching, lifecycle events, and settlements.
• Design and implement risk and P&L attribution frameworks, leveraging Python/SQL to parse large datasets and deliver real-time or end-of-day exposure, VaR, and stress analytics.
• Work directly with traders and quants to monitor margin utilization, capital efficiency, and risk constraints across venues; contribute to tooling around execution algo performance and post-trade analysis.
• Act as a technical operations liaison with Treasury, Finance, and Risk teams to ensure accurate trade capture, funding, and fee allocation.
• Develop monitoring scripts, dashboards, and alerts to track operational anomalies, portfolio drifts, or data inconsistencies—taking a programmatic approach to error reduction and efficiency.
• Assist with the structured product lifecycle from a middle-office lens, including digital options, variance products, and on-chain derivatives where applicable.
• Stay on top of evolving options market structure, risk methodology, and cross-venue margin requirements; contribute to internal tooling and documentation on these topics.
