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.
Marshmallow are looking for engineers to tackle complex challenges. So we can make migration easy for hundreds of millions of relocators around the world. Across frontend, backend and full stack, working alongside designers, data scientists and product managers; you’ll be at the heart of every solution we offer.
Builders of dynamic new products. Pioneers of new tools and technologies. Open collaborators. Clear communicators. Engineers take ownership of projects from end-to-end to turn goals and vision into reality. With a clear view of where the business is headed and resources readily available to make sure we get there.
You’ll have real-world impact creating trailblazing products, true visibility across the business, and the support to share your ideas, ask for what you need and progress.
Learn fast and move forward with an engineering career at Marshmallow.
