Requirements
• High AI agency: You actively experiment with AI in your analytical and technical workflows. You use tools like Claude Code, Codex, or similar to build, automate, and accelerate substantive work. You have a clear view on how AI changes what a data science team does and a track record of raising capability across the people around you, not just your own output. • Transformation track record: You have led a meaningful shift in how an analytical or data science team works. You are comfortable navigating resistance, building adoption across different types of people, and making change persist beyond your direct involvement. • Technical background: You have a background in probability, statistics, or a related quantitative field, with hands-on experience building and overseeing probabilistic ML models on structured commercial or financial data. • Production experience: You have managed the full lifecycle of models in production – deploying, monitoring, and retiring them. You are comfortable coordinating chains of model dependencies across different teams. • Commercial acumen: You understand how modelling supports business decisions and know when to make trade-offs between depth, delivery time, and value. • Strategic leadership: You have experience setting data science strategy, aligning work with commercial goals, and translating technical modelling for senior stakeholders so they can act on it. • People and team: You have experience managing a data science team, setting clear standards, and developing people – including having direct conversations about where the gap is and how to close it. • Domain experience: You have worked in credit risk, lending, or customer lifetime value modelling. • Function scale: You have led a data science team of 20 or more people across multiple teams. • R&D and forecasting: You have experience shaping a modelling agenda, including probabilistic or long-term forecasting work. • Industry profile: You have represented a data science team externally – industry events, publications, or advisory roles.
