Principal Data Scientist

About Marshmallow

We started Marshmallow when we found out how unfair insurance prices are for people who move to the UK. All because the industry hasn't given this huge cohort of people a second's thought, and isn't set up to price them properly.

We saw an opportunity to do things differently, so we made it our mission to back the ones who step outside the norm. Since we started, we've helped 100,000s of people get a fairer deal on their car insurance. Using technology, we serve people that are often overlooked by financial services companies, solving important problems for people who need it most.

We know there are millions of marginalised customers out there. And we know that they face unique problems that most companies aren't even aware of. We believe that our future is helping these people by learning about their experiences, and building our company around their needs. And there are strong signs that there's a need for a company like us. Earlier this year we hit profitability, which is a huge milestone, but the most exciting thing is that we're only just getting started.

How we work

We're really proud of the culture we've created. We push for progress every day, because we know that we'll only hit big milestones by taking lots of smaller steps. We're always open to helping our team mates, sharing our ideas, experience and knowledge to solve problems together. We take risks, think creatively and experiment relentlessly to meet our customer's needs, and never pass blame when things go wrong. We encourage people at all levels to take ownership of their work, and to be bold in challenging how we do things. Everyone has a voice and the opportunity to make an impact.

And autonomy and ownership are only possible with clear direction. That's why we collaborate to do in-depth planning twice a year, and make sure we leave with clear goals and objectives that flow from top to bottom. To make sure we're as aligned as possible across functions, most of our work rolls up into four tribes; Acquisition, Retention, Claims and Pricing, Underwriting & Fraud. Each tribe has multiple teams embedded in it, working cross-functionally to do great work.

We're so excited for all of the challenges up ahead, and we need more people to help us tackle them! If life at Marshmallow sounds like it could be for you, explore our culture handbook or read our blog to find out more.

The Data Science TeamWe're here to generate insights and actions from all the data we can get our hands on. This includes analytics, predictive modelling, and prescriptive recommendations. We deliver high-impact work to the business, focusing on high-risk, high-reward projects, and making sure all decisions are data-driven.

We're looking for a Principal Data Scientist to help us push our claims tribe to the next level. We want to build a seamless customer experience for individuals going through our claims journey - automating and streamlining all decision points. Ultimately this will save the company money but, very importantly, it will transform the customer experience during this difficult time.

This is only the beginning of Data Science's journey to be a key innovator at Marshmallow and in the wider insurance industry. We're really excited to build on what we've done and emerge as a market leader in this space.
