Build and scale a top finance app on iOS and Android that directly impacts the financial lives of hundreds of thousands of users, growing to millions as we expand our advancing, credit building, and future banking products. Own end-to-end feature development across the user lifecycle - from the first identity verification and onboarding flows to cash advances, cash flow management, income earning opportunities, to account management experiences. Integrate with financial service providers (Plaid, Stripe, Tabapay) and internal APIs, building robust mobile interfaces that handle sensitive financial data with accuracy and security at scale. Develop reusable components, design system elements, and feature scaffolds that accelerate experimentation velocity across our multi-brand mobile platform (Grant, Kikoff, Banking). Enhance mobile platform foundations - improving build systems, CI/CD pipelines, code generation tooling, and developer velocity for our growing team. You'll work closely with product, data science, and operations teams to ship features that directly impact customers' financial wellbeing while maintaining the highest standards of reliability, security, and compliance.
