About the role

Data Scientist - Partner Flow - UK Hybrid in London, United Kingdom We're looking for a Data Scientist to join the Partner Flow team. You'll use experiments and causal inference to shape how iwoca grows through its partners – the fintechs and platforms that offer iwoca lending inside their own products. The company Small businesses move fast. Opportunities often don't wait, and cash flow pressures can appear overnight. To keep going, and growing, SMEs need finance that's as flexible and responsive as they are. That's why we built iwoca. Our smart technology, data science and five-star customer service ensures business owners can act with the speed, confidence and control they need, exactly when it's needed. We've already cleared the way for 100,000 businesses with more than £4 billion in funding. Our passionate team is driven to help even more SMEs succeed, through access to better finance and other services that make running a business easier. Our ultimate mission is to support one million SMEs in their defining moments, creating lasting impact for the communities and economies they drive. The team Partner Flow owns the journey for small businesses that come to iwoca through a partner platform, from how they discover iwoca’s business finance to any repeat lending. The aim is to reach each business at the right time, make it easy to apply and get funded, and match them with the offer that suits them and works best for iwoca over time. The team works on three parts of that journey: • The application. Making it smooth and collecting the data a credit decision needs. • Routing. Working out which applications get an automatic decision and which need input from a credit analyst. • Offer terms. Testing amount, duration, and interest rate, working closely with Credit Risk Modelling, who build the credit models. The team is small and cross-functional – data science, engineering, design, and product – and works across the full application stack, from the APIs partners integrate with to the experience customers see when they apply. The role As the Data Scientist in Partner Flow, you'll run the analysis behind the team's product decisions. Most of it is experiment design and causal inference, with some model building and funnel analysis. You'll own each project from the start. You'll work out what the business needs, reason from first principles, weigh the trade-offs, and shape the project with product, commercial, and strategy colleagues before deciding how it gets done. The team's analytical approach is still young, so you'll help set its methods. Around 10% of your time is for research and learning – finding better methods for the problems in front of you, or new ways to add value. You'll work with data scientists in iwoca's other customer flow teams, and join the analytics guild – iwoca's data science community – to align on methods and build your expertise. Your results reach the wider business through Learnings – short write-ups of what an experiment found, shared at weekly and fortnightly sessions. Live project examples: • Pre-qualification. Measuring how showing customers what they could borrow before they apply affects conversion and Customer Lifetime Value (CLtV), then shaping how the model behind it develops. • Credit cards. Working out which customers should see iwoca's recently launched credit card, a Flexi-Loan, or both – and whether the card wins extra customers or takes them from Flexi-Loan. • Top-up notifications. Measuring whether letting eligible customers know they can borrow more increases CLtV, using causal inference methods beyond a standard A/B test. • Partner funnel. Building a clear view from application to drawdown, finding where customers drop off, and testing fixes where they'll matter most. The requ
