Head of Data Science

Join to apply for the Head of Data Science role at iwoca Deutschland Overview Hybrid in London, United Kingdom. You’ll lead multiple data science teams whose work guides decision‑making across lending, product, operations, and strategy. You’ll shape how we work, ensuring that analytical insight directly influences the choices that matter most at iwoca. Responsibilities Strategic direction: Work with team leads and senior data scientists to plan, sequence, and review projects, maintain consistent standards of reasoning, communication, and methodology. Decide where modelling adds value and where a lighter heuristic approach could be more effective. Technical and people leadership: Oversee hiring and development, ensuring assessment, progression, and knowledge‑sharing are fair, structured, and suited to a growing multi‑team environment. Shape how data science is applied at scale – how uncertainty is communicated, how analytical support is allocated, and how the function directs its effort to the highest‑value work. Collaboration with engineering and business teams: Coordinate with Engineering, Product, and Operations teams so that projects are properly scoped, resourced, and aligned with wider priorities. Represent the function in discussions that shape lending, risk, and product decisions by explaining assumptions, highlighting risks, and helping senior stakeholders act on analytical insight. Qualifications Strategic leadership: You have experience setting data science strategy and aligning work with commercial goals. You can translate technical modelling for senior stakeholders, make assumptions explicit, and shape the decisions that follow. 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. Team development: You have a track record of hiring and developing data scientists, and establishing consistent standards for planning, peer review, and methodology. Technical background: You have a background in probability, statistics, or a related quantitative field such as mathematics or physics and can evaluate analytical work for conceptual soundness.
