At Marshmallow, our developers push the boundaries of what is possible in a financial services company by having the freedom to work on a mainly greenfield project.

The primary responsibility of this role is to work build out scalable and efficient backend services to support a company that is going to experience significant growth.

But it also involves driving roadmaps, inputting on business strategy, getting to know customers, making actionable and autonomous decisions - and having real responsibility.

We don't believe in the top of the funnel making all the decisions - corporates do that, and if there's one thing we're not it's corporate. Instead, we are building a company of the future where everyone is a decision maker. There is no micro-management, but you will be part of a team where everyone is exceptional, smart and collaborative - so you can expect a lot of support!!
