About Marshmallow
We build financial products that accelerate the economic freedom for people who move across borders. We started with car insurance — insuring over a million drivers — and we’re scaling beyond. Tens of millions of people move countries each year, facing overlooked financial challenges. Our future is in building financial products around their needs to positively impact their lives.
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 three tribes; Acquisition, Retention & Claims. 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 to find out more.
Engineering at Marshmallow
Our engineers are at the heart of the solutions. They work on product builds from start to finish, solving lots of challenges to help us build fast and scale up! Our engineers cover a range of skills across frontend, backend, fullstack, iOS and android and work alongside designers, data scientists, researchers and product managers within our product teams.
Our product teams include: the Growth team, the Efficiency team, and the Claims team (to name a few!) Each team sets its own roadmap and actively pushes our codebase forward.
The Mobile Team you'd be joining
Our Mobile Team's mission is to build the best app in the business. That means creating a truly customer-first experience that makes the difficult (but essential) things easy, quick and intuitive.
You’ll work directly with our users to get a full picture of our customers and the problems we can solve for them. And you’ll do that as part of a cross-functional team to build a platform that is an essential part of their inclusive, easy-to-use and empathetic Marshmallow experience.
What You'll Be Doing
