iOS & Android Mobile Developer — Fintech Experience Preferred

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:

• Small team, real ownership: no micromanagement, working directly with the CEO/CTO
