About the company

Allica Bank is the UK's fastest growing company and the fastest-growing financial technology (Fintech) firm ever. Its 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 the economy, yet have been largely neglected by both traditional high street banks and modern fintech providers. You'll join a small, senior team with a direct line to the CTO and a clear mandate. The team moves quickly but holds a high bar for quality and responsible deployment — because it's a bank, and customers rely on it.
