Job description

London

Our client, a leading FinTech firm at the heart of electronic trading platforms, are looking for a Surveillance Analytics Lead to help modernise and elevate a global Fixed Income surveillance framework.

This is not a traditional alert-review role - the ideal candidate is a hands-on surveillance specialist who enjoys building, optimising and refining detection frameworks, shaping alert logic, and embedding data-driven methodologies across a complex trading environment.

You will play a key role in transforming a legacy surveillance capability into a scalable, AI-ready, analytics-driven control framework. The environment is collaborative, cross-functional and strategically focused, with direct exposure to senior stakeholders and meaningful influence over future surveillance architecture.

The Role

• Design, calibrate and optimise surveillance alert scenarios across Fixed Income asset classes
• Reduce false positives while maintaining high detection sensitivity and regulatory robustness
• Integrate new business initiatives into the surveillance framework
• Prepare, clean and model large trade, order and market datasets
• Use Python (NumPy, Pandas, Matplotlib) and SQL to drive data-led insights and alert calibration
• Build expert-level Tableau dashboards for alert activity, calibration outcomes and executive reporting
• Support the evolution of AI-driven surveillance capabilities and data automation
• Influence stakeholders across Compliance, Technology, Risk and Front Office globally

Core Requirements

• Strong experience designing, tuning and calibrating trade surveillance alerts
• Advanced Python, SQL and Tableau capability (data preparation, analytics, visualisation)
• Strong statistical knowledge (distributions, regression, clustering, anomaly detection)
• Experience preparing structured and unstructured datasets for AI/ML applications

This role sits between Surveillance Specialist and Surveillance Lead - offering immediate ownership and delivery responsibility, with a clear pathway into formal leadership as the function continues to scale.
