Marshmallow is a company that was started with the aim of providing fair insurance prices for people who move to the UK. We use technology to serve people that are often overlooked by financial services companies, solving important problems for people who need it most. We are proud of the culture we’ve created, where we push for progress every day, take risks, think creatively and experiment relentlessly to meet our customer’s needs.

This role will sit in the Pricing Team, reporting into the Head of Pricing. The team is responsible for managing our loss ratio, underwriting footprint, broker optimisation and growth targets. We work in a very different way to most pricing teams that you might be familiar with. We all take ownership, move fast, innovate and deliver changes to our rates at high frequency.

As a Senior Pricing Data Scientist, you will be developing a deep understanding of Marshmallow’s quote, policy and claims data and use this to derive insights that can be used to enhance our pricing. You will be conducting claims analysis and claims modelling using SQL and Python, conducting price optimisation analysis/modelling using Python, building and deploying models in APIs for use in real time pricing, and working with other members of pricing to recommend changes and monitor their impact.

We offer flexible working, a competitive bonus scheme, a flexible benefits budget, mental wellbeing support, learning and development opportunities, private health care, a medical cash plan, a tech scheme, and 33 days holiday (including bank holidays). We also have a pension scheme, a cycle to work scheme, and monthly team socials and company-wide socials every month.

We are committed to hiring without judgement, prejudice or bias and encourage everyone to apply for our open roles.
