Job Description

We’re on a mission to make migration easy.

We started building Marshmallow in 2017. Since then, we’ve grown from 3 to 700+ people, gained unicorn status, raised ~£140M over three funding rounds, turned profitable, insured millions of drivers and lent millions in car loans.

But we’re only just getting started. Our goal is to become one of the largest financial services providers in the world. Over the next 10 years we’ll grow exponentially, not only by scaling our existing products, but also by building new ones.

To achieve our goals we need incredibly ambitious, commercially driven people who never settle for ‘good enough’. Marshmallowers are hungry for autonomy and ownership, and would rather improve than coast. Everyone raises standards and has an impact, with a focus on collective success over self-interest.

We’ve created an environment where curious, tenacious people win and grow together. If that sounds motivating, this could be the place for you.

The Claims Fraud Team

We defend Marshmallow against fraudulent activity and help protect the company! Fraudulent claims can result in us losing money, which can drive up the premium prices for all of the other customers. We’re here to stop that, making sure Marshmallow remains affordable and accessible for everyone. We’re looking for a Claims Fraud Investigator to play a key part in making sure that we deliver a top service for our customers.

Our process

  • A skill-based interview where you will discuss your previous experience also with a focus on our values, our culture and your motivations with our Claims Fraud Leads (60 minutes)

We’ll let you know if you’re invited to an interview or not. But, as a small team with a lot of applications to consider, we can’t give individual feedback on each application
