Griffin is a regulated bank (PRA-authorised, FCA-regulated) offering embedded banking via API. The tech stack reveals a functional-programming-first backend (Clojure, FoundationDB) paired with modern frontend tooling (React, Storybook), now adopting Svelte — a shift toward lighter, faster UI frameworks. Active hiring is heavily weighted toward engineering (9 of 16 roles), with projects spanning faster payments, card issuing, cross-border transfers, and term deposits, suggesting a platform rapidly expanding its financial-product surface area beyond core accounts.
