Data Scientist (iwocaPay Risk Squad)

Salary: £70,000 - 110,000 per year

Requirements:

• Expertise in supervised machine learning on tabular data, with experience building and iterating production models end to end from exploration through deployment and monitoring. • Strong statistical foundations in probability, uncertainty quantification, model calibration, and reasoning about where a model is likely to be wrong. • Ability to work independently in a messy, early-stage environment, including scoping problems, building infrastructure, and shipping models autonomously. • Pragmatism about what good enough looks like commercially, balanced with rigour on high-stakes models. • Data engineering capability, including building pipelines and managing datasets alongside modelling work. • AI fluency, using AI to build, automate, and accelerate substantive analytical and engineering work. • Clear communication, with the ability to adapt technical detail for non-technical colleagues in product, risk, and leadership. • Python proficiency, as this is what our team uses day to day. • Bonus: experience with credit risk modelling or financial services lending. • Bonus: familiarity with transfer learning, domain adaptation, or techniques for combining datasets of different sizes and relevance. • Bonus: experience with non-linear models such as gradient boosting or neural networks on tabular data in production settings.
