The team The Repeats team is responsible for the lending product strategy and digital user experience of recurring customers. They are responsible for all the product decisions that occur after a customer has taken their first funding. This includes the user journey eligibility and documents requirements and offer terms (such as offered amount or pricing), among other things.

The role iwoca's Data Scientists specialise in supervised machine learning, statistical inference and exploratory data analysis, focusing on tabular and time-series data. Their work emphasises quantitative predictions through the analysis of conditional probabilities and expectations, using medium-sized datasets. Your primary focus will be to figure out the best document requirements and offer terms (pricing, amount, duration, additional product features, etc.) to maximise user conversion and value to iwoca. You will look at observational data, identify hypotheses for unknown relationships, figure out their commercial relevance, and design and implement tests to prove or disprove your theory.

Strategy and innovation: Work closely with the Repeats team lead and tech leads to identify and quantify opportunities within the customer journey, based on past data or modelled assumptions. Design experiments to compare the performance of different strategies and evaluate them rigorously to make unbiased decisions. Share your findings and modelling with the wider business to impact strategy. iwoca lives and breathes data as a company, so data scientists play an important role in decision‑making.

Ownership and influence: Own some of our monitoring and data pipelines, covering all aspects of existing customers' user journey, and getting the data we need to make informed decisions. Lead the move away from rule‑based policies towards machine learning approaches to improve predictive accuracy and optimise decision‑making. Promote analytical rigour within the team, ensuring that our experimental designs are correctly defined and that we evaluate tests without bias.
