Job description

Are you a markets professional who enjoys turning large, complex datasets into answers?

• Analysing large sets of market and trade data, using SQL, Python and AI-assisted workflows, to detect, evaluate and explain unusual trading patterns and assess potential risk.
• Building and automating detection logic, tooling and data pipelines, including AI and machine-learning driven systems, that make surveillance faster, sharper and more scalable.
• Leveraging AI workflows and systems to investigate alerts and surface risk more effectively, and helping design, build and refine those systems.
• Designing and testing controls to detect and prevent market abuse, then measuring whether they actually work.
• Contributing to the execution and continuous improvement of the Compliance monitoring and surveillance framework.
• Reviewing surveillance electronic communications alerts, and following them up to resolution.
• Combining technical skill with a solid understanding of the regulatory framework to keep our controls fit for purpose.
• Identifying gaps in the surveillance framework and pushing improvements that mitigate the firm's biggest risks and enable growth.
• Advising on and supporting the implementation of compliance requirements.
• Building strong communication lines across functions to enhance collaboration.

Who You Are

• 2+ years of relevant experience in trade surveillance, market abuse monitoring, or a related markets, data or compliance-technology role.

• Strong data skills, preferable to have hands-on experience using SQL or Python to analyse large datasets.
• Experience automating analysis or building data tooling is a strong plus.
• A genuine interest in using technology and data to solve problems in financial markets and trading.
• Excellent written and verbal communication skills in English.
