Senior App Developer (React Native)

Prosper is on a mission to revolutionise how we save for the long term. We believe that legacy solutions are expensive, the language often complex, the charges obfuscated and the digital experiences dated and clumsy.
New solutions to long-term saving tend to be focused on the first-time investor and heavily biased toward trading, as opposed to saving for the long term. We need better software to help consumers achieve their life goals, not to be sold financial products.
We work as a lean, agile team, testing our ideas quickly and cheaply, iterating to keep heading for the best solutions for our users.
Our founders are Nick Perrett, CEO and Ricky Knox, Chairman. Between the two, Nick and Ricky have raised over half a billion for businesses they have been involved in. They have assembled an incredible set of angel investors in Prosper who have co-founded leading financial services businesses, such as Capital One and Monzo, with a cumulative exit value of well over a billion .
We know there’s not much to see in the wild about us… yet! But get in touch, and we can show you what we’re working on.
We're inclusive and are actively looking to encourage people from different backgrounds and with different ways of thinking to apply.
