Company Description

Profitable £3.5bn fintech unicorn backed by Balderton, Goldman Sachs, and Ontario Teachers' Pension Plan

Job Description

You will build the proprietary machine learning models that sit at the core of this fintech’s competitive advantage. Focusing on the US market, you’ll develop real-rate, risk-based pricing scorecards for unsecured loans and credit cards. This is an end-to-end role involving model design, deployment, and monitoring using state-of-the-art ML techniques.

Location

London, UK

Why this role is remarkable

Join a £3.5bn fintech unicorn that has been profitable since 2017 and is backed by elite investors like Goldman Sachs. Take full ownership of credit risk models for the massive US market, working with a rich repository of proprietary financial data. Experience a high-growth environment with in-house chefs, hybrid flexibility, and a mission-driven team disrupting dated banking systems.

What You Will Do

Design, implement, and deploy end-to-end machine learning models to optimize credit risk, pricing, and marketing efficiency. Extract and transform complex data sources using Python and experiment tracking tools like MLFlow to drive scorecard development. Mentor junior data scientists while collaborating with multidisciplinary teams to translate business problems into advanced technical solutions.

The ideal candidate

Proven experience building and shipping production-grade machine learning models in Python with a focus on real-world commercial impact. Strong communicator capable of explaining complex risk modeling topics to non-technical stakeholders and business leadership. Previous exposure to credit risk decisioning or financial services data, particularly across UK or US geographies, is highly advantageous.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
