Summary
Own the mobile side of Payle end to end — a fintech product building payment infrastructure for AI agents. You'd build the spend-approval flow (Face ID), agent chat concierge, card stack UI, and savings features using React Native/Expo, TypeScript, Swift native modules, with a Go backend.
Compensation: $30k – $50k • 0.5% – 1.0%
Payle is building the money layer for AI agents. The financial infrastructure that lets autonomous AI software pay for things under human-defined rules.
You would own the mobile side of Payle end to end.
What you'd build:
- The approval moment: "Your agent wants to spend $18 — approve?" One tap, Face ID. Mobile-first. The most important screen in the product.
- Chat concierge: users talk to their agent through a chat interface with tool cards, comparison cards, and receipts
- Card stack UI: one user, many financial identities — each agent gets its own card
- Savings section: FDIC-insured deposits with auto-sweep between spending and savings
- Design system.
You:
- React Native / Expo experience — you've shipped apps to the App Store
- Swift knowledge for native modules (Face ID, APNs push, local authentication)
- You understand that a fintech app is not a social media app: the approval moment is not a "like" button, it's a decision about money
- Design sensibility: you care about the gap between "it works" and "it feels premium"
We use:
React Native + Expo (dev client EAS), TypeScript strict, Tailwind, Reanimated, expo-notifications, expo-local-authentication. Design tokens already defined. Backend is Go with typed API contracts.
Design system exists in Figma.
Deadline: Open until filled. We review applications weekly.
