Global Head, Data Science

About the Role

Grade Level (for internal use): 15

The Enterprise Solutions Technology team is dedicated to delivering next generation, high scale technology platforms through resilient architecture, data excellence, and engineering innovation. Our mission is to enhance our digital presence and improve customer engagement across various domains, including Lending, Corporate Actions, Tax, Regulatory & Compliance, Regulatory Reporting, Public Markets, and Private Markets portfolio monitoring.

We are seeking a Data Scientist Leader to design, develop, and operate high rigor analytical and machine learning systems across a complex, regulated financial services estate.

This is a strategy led and hands on applied data science and ML engineering role, responsible for defining the AI/ML roadmap for Enterprise Solutions while also building high rigor analytical and predictive models for anomaly detection, variance analysis, drift detection, market and behavioral signals, forecasting, and prediction. The expectation is production grade models, comparable in rigor to fraud, risk, or surveillance systems.

Responsibilities

• Strong experience delivering applied data science and machine learning in production within banking, capital markets, or similarly regulated, data intensive environments.
• Deep grounding in statistics, machine learning, time series analysis, and predictive modelling, with experience building models under real operational constraints.
• Hands on ownership of the full model lifecycle: data exploration, feature engineering, model development, back testing, validation, deployment, monitoring, and ongoing tuning.
• Extensive experience working with large, complex, and imperfect datasets, including missing data, outliers, regime changes, noisy labels, and evolving schemas.
• Strong understanding of production ML system design, including batch vs real time inference, model serving patterns, performance trade offs, and failure modes.
• Experience operating models in production over time, including versioning, drift detection, retraining strategies, and incident response when models misbehave.
• Practical experience designing explainable models suitable for regulated environments, including feature attribution and model transparency techniques.
• Experience combining statistical models, ML, semantic models, and rules based logic where needed to achieve accuracy, stability, and explainability.
• Strong focus on data quality, anomaly detection, and monitoring, including metrics that surface real issues and drive sustained improvement.

Experience & Mindset

• 20+ years working with analytics, data science, or ML systems in production, with significant experience in financial services or other regulated, high availability domains.
• Comfortable working directly with data, models, and code, and collaborating closely with software engineers and platform teams.
• Pragmatic and outcome driven; measures success by models that run reliably in production, adapt to changing conditions, and withstand scrutiny.
• Clear communicator who can explain modelling choices, assumptions, and limitations to engineers, product partners, and senior stakeholders.
• Acts as a technical mentor to other data scientists through review, pairing, and example, with limited people management where appropriate.
