Staff Fullstack Engineer

About Allica Bank

Allica is the UK’s fastest growing company - and the fastest-growing financial technology (Fintech) firm ever. Our purpose is to help established SMEs, one of the last major underserved opportunities in Fintech.

Established SMEs are the backbone of local communities - representing over a third of our economy - yet have been largely neglected both by traditional high street banks and modern fintech providers.

Department Description

Technology sits at the centre of Allica. We design and build the platforms that power the bank, working closely with every part of the business to deliver real impact for customers.
