Department IT
Employment Type Permanent
Minimum Experience Mid-level




Jaja is an innovative UK based consumer finance business. Leading initially with a digital credit card launching in 2018, and a pipeline of consumer finance solutions in the making. Working closely with our scheme provider and leveraging our own consumer credit license authorised by FCA, we are challenging an industry that has seen little real innovation in nearly twenty years.

In July 2019 Jaja led a consortium which purchased the Bank of Ireland credit card portfolio, investing over £0.5bn. It also resulted in fresh investments in Jaja from major Private Equity funds including Centerbridge and KKR who have recognised the change that Jaja is bringing to the market.

As a result the business is growing rapidly and we are on the lookout for great talent across the organisation.




We are on a mission to redefine the consumer finance experience and liberate customers from needless complexity, wasted time and frustration. Or as we say it, Make Simple. We will delight our customers – making the customer experience simpler, more enjoyable, more intelligent – treating customers fairly and giving them more control of their money.
