iOS & Android Mobile Developer — Fintech Experience Preferred İş İlanı

Juuli is an AI-native, vertical finance platform for 43M+ solopreneurs across Europe. We bring wallet, money transfers, card issuing, and AI-powered tax/accounting automation together into a single business account — so solopreneurs can run their business without needing separate accounting software. Based in London and Tallinn, our 15-person team is growing 3x every month and we're operationally profitable. We've grown this far without a mobile presence. That's about to change — and whoever takes this role gets to be the architect of Juuli's first mobile app. What you'll do: Design and build Juuli's iOS and Android apps from the ground up (native or cross-platform — you'll shape the approach) Integrate end-to-end with our own backend API Bring wallet, money transfers, and card management to life as the core mobile modules Work meticulously on security, KYC/compliance flows, and sensitive financial data handling Shape product and engineering decisions directly within a small, fast-moving team What we're looking for: Strong, shipped, production experience in iOS (Swift/SwiftUI) and/or Android (Kotlin) — having built both natively, or deep experience with cross-platform frameworks like Flutter/React Native, is a plus Solid command of REST API integration, secure data storage (keychain/keystore), push notifications, and app store release processes Fintech, finance platform, or payments experience is a strong plus Comfortable with ambiguity, able to ship a lot with limited resources, strong sense of ownership Can match the speed and flexibility of an early-stage startup Why Juuli: Remote-first working model Small team, real ownership: no micromanagement, working directly with the CEO/CTO
