About the Company

Imagine a world where every small business has the power to thrive. Since 2012, we have revolutionised how these businesses access finance, turning what was once a lengthy, frustrating process into fast, flexible, and truly effective funding. We have provided billions in funding to more than 150,000 businesses across Europe, empowering one million businesses with the financial tools they deserve.


The Function

iwoca’s Data Scientists specialise in supervised machine learning, statistical inference and exploratory data analysis, focusing on tabular and time‑series data. Our work emphasises quantitative predictions through the analysis of conditional probabilities and expectations, using medium‑sized datasets.


The Team

The New Applications Team optimises the customer journey from signup to offer generation, identifying and implementing the most efficient ways to convert prospects into successful applicants.



  • Optimise the customer journey: streamline the path from brand awareness to enthusiastic applicants.
  • Strategise customer assessments: determine when and how to run credit checks to maximise conversion rates.
  • Promote data efficiency: continually improve data collection from applicants and third‑party sources, minimizing wait times for decisions.

The Role

As a data scientist on the New Applications team, you will work closely with the team lead to identify opportunities and develop strategies for maximising value from customers who arrive at signup. You will quantify opportunities based on past data or modelled assumptions and design experiments to test them. You will champion analytical rigour, ensuring experimental designs are correctly defined, models are optimised for impact, and results are evaluated rigorously and unbiasedly. You will also mentor and guide data and product analysts on the team.


The Projects

  • Design, implement and review experiments that test the impact of giving instant decisions to different customer segments.
  • Collaborate with the team lead and other teams to develop an optimised strategy for deciding which documents to request from customers, including building and maintaining predictive models.
  • Evaluate and experiment with integrating an LLM chat assistant into the sign‑up journey, optimizing for conversion and data quality.
  • Improve and maintain time‑series models that predict loan issuance numbers and other financial metrics.

The Requirements

  • Strong problem‑solving skills in probability and statistics, ideally from a quantitative background (e.g., Mathematics, Physics, Statistics).
  • Ability to understand business context and translate data into actionable insights that guide decisions.
  • Understanding of experimental design.
  • Proficiency with data manipulation and modelling tools, e.g., pandas, statsmodels, R.
  • Ownership mindset, driving projects toward end‑to‑end responsibility.
  • Excellent communication skills, adapting technical detail to different audiences.

Bonus Skills

  • Proficiency in Python, our primary programming language.
  • Experience in machine learning model development and evaluation.
  • Experience with SQL and business intelligence tools such as Looker.
  • Understanding of Bayesian statistics.
  • Experience building or maintaining data pipelines (Snowflake/dbt valuable).
  • Experience using LLM APIs in a production environment.

Compensation

We expect to pay from £70,000 – £90,000 for this role. Salary benchmarks are reviewed quarterly, and we encourage candidates to include their salary goals with their application.


Culture & Values

We prioritise a culture of learning, growth, and support. We value diversity of thinking and encourage exploring new areas of interest to drive innovation.


Offices

  • London, Leeds, Berlin, and Frankfurt with plenty of drinks and snacks.
  • Events and clubs, including bingo, comedy nights, football, etc.

Benefits

  • Flexible working hours.
  • Medical insurance via Vitality, including discounted gym membership.
  • Private GP service for you, your partner, and dependents.
  • 25 days holiday per year, an extra day for your birthday, and the option to purchase or sell additional leave.
  • One month fully paid sabbatical after four years.
  • External counselling and therapy sessions for emotional or mental health support.
  • 3% pension contributions on total earnings.
  • Employee equity incentive scheme.
  • Parental leave and nursery tax benefits.
  • Electric car and cycle‑to‑work schemes.
  • Two company retreats a year across Europe.
