Monzo is hiring a Lead Machine Learning Scientist for its Business Banking team, one of the first ML scientists there. The role is a hands-on technical lead building and shipping models — LLM-powered experiences, predictive models and time-series forecasting — on a cloud-native data platform, plus evaluation, monitoring and MLOps collaboration. The posting asks for multiple years shipping ML to production, fluent Python, scikit-learn and SQL, willingness to learn Go, and comfort with ambiguity. Distinctive: a leadership-through-ambiguity mandate and a strong emphasis on responsible ML in financial products.
