Data Scientist - Repeats Team in Harrow on the Hill

Overview

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.

iwoca is a company that supports small businesses with smart technology, data science and customer service to provide fast and flexible finance. We’ve cleared the way for 100,000 businesses with more than £4 billion in funding. Our mission is to support one million SMEs in their defining moments, creating lasting impact for the communities and economies they drive.

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, including the user journey eligibility, documents requirements and offer terms (such as offered amount or pricing).

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.

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.

Development Opportunities

• Join our community of analysts/data scientists/statisticians to ensure alignment in methodology across iwoca.
• You’ll be part of a peer group with whom you can discuss best practices or the latest advances so that you share and deepen your technical expertise.
• Build expertise across the full range of the Repeats funnel, from the user journey to the lending strategy, learning to understand how customers evolve in our complex environment.

Essential

• Expertise in probability and statistics, gained through work in a quantitative field such as Mathematics, Statistics, Physics, Engineering, or similar.
• Ability to understand business context and translate data into actionable insights that guide decisions.
• Proficiency with data manipulation and modelling tools such as pandas, statsmodels, or R.
• Experience with scientific computing tools such as NumPy or SciPy.
• Ability to work autonomously and manage analytical work from framing the question through to making a recommendation.
• Ability to communicate clearly in writing and speech, adapting technical detail to different audiences.

Bonus

• Understanding of Bayesian statistics, including interest in or experience with hierarchical models.
• Experience building or adapting statistical or machine-learning models, with an interest in understanding the underlying methods.
• Familiarity with stochastic modelling concepts as they apply to inference, time series, or uncertainty.
• Understanding of financial concepts such as pricing or loss rates.
