Lead Pricing Data Scientist in London

We exist to make migration easy. Every year, millions of people move to a new country and find themselves cut off from essential financial services. We built our own technology to change that, insuring millions of drivers and lending millions in loans. But we're not standing still. Our ambitions are huge, and we need exceptional people to supercharge our growth and shape what comes next. Marshmallow is a place for do-ers. People who are tenacious, hungry for ownership, and unfazed by complexity. But collective success always comes first - people here win and grow together.

Pricing at Marshmallow is where the mission gets real — delivering unbeatable prices that make migration easy. You'll work with vast, proprietary data, cutting-edge models, and engineers who can implement your ideas fast. Ownership isn't a buzzword here — you'll have the autonomy to make decisions and the senior backing to act on them. This is a team that moves fast, challenges assumptions, and delivers change at high frequency.

What you’ll be doing

• Develop a deep understanding of Marshmallow’s quote, policy, and claims data to derive insights that enhance pricing strategies.
• Contribute to key pricing initiatives, including expansion plans and customer retention efforts.
• Communicate analytical findings effectively to senior leaders and cross-functional teams.
• Conduct data analysis using SQL and Python to drive decision-making.
• Support the deployment of models in APIs for real-time pricing applications.
• Collaborate with pricing team members to recommend changes and track their impact.
• Assess new external data sources to refine claims risk evaluation and quantify their value.
• Monitor the performance of our business and contribute to our governance and control processes such as reviewing business mix and segmental loss ratio performance.
• Work closely with Engineering and ML Engineering teams to implement pricing strategies.
