Data Scientist - Partnerships Strategy in London

We’re looking for a Data Scientist to join our Partnerships Strategy team. You’ll shape how iwoca works with partners by influencing pricing, commission, and engagement decisions that drive more than half of our new customer acquisition.

The Partnerships Strategy team supports iwoca’s commercial teams by turning partner performance and behaviour into clear, data-led guidance. The team analyses experiments and builds models to understand how pricing, commission structures, and partner engagement affect customer acquisition and profitability. It works closely with partner-facing teams to translate business questions into quantitative problems and to present evidence in a way that supports sound, timely decisions.

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. Working in the Partnerships Strategy team, you’ll model customer price sensitivity to support pricing strategy, analyse differences in how partners operate to guide commercial treatment, and evaluate how relationship management effort translates into performance and profitability.

The requirements:

• 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 deterministic cash flows.

The salary: We expect to pay from £60,000 - £90,000 for this role, depending on experience. But, we’re open-minded, so definitely include your salary goals with your application.

The culture: At iwoca, we prioritise a culture of learning, growth, and support, and invest in the professional development of our team members. We value thought and skill diversity, and encourage you to explore new areas of interest to help us innovate and improve our products and services.

The benefits:

• Flexible working hours.

• A private GP service for you, your partner, and your dependents.
• 25 days’ holiday per year, an extra day off for your birthday, the option to buy or sell an additional five days of annual leave, and unlimited unpaid leave.

• Instant access to external counselling and therapy sessions for team members that need emotional or mental health support.
• 3% Pension contributions on total earnings.
• An employee equity incentive scheme.
• Generous parental leave and a nursery tax benefit scheme to help you save money.
• Electric car scheme and cycle to work scheme.
• Two company retreats a year.
