Rain is the world's first AI Financial Health Platform, serving 3.5 million employees at leading organizations like McDonald's, Marriott, and T-Mobile. Rain works in the background to optimize every employee's financial life to prevent shortfalls and build long-term stability. Backed by top investors including QED and Prosus, Rain has raised $150M in venture funding to fuel our next stage of hyper growth.
As a Senior Mobile Engineer, you will develop, test, and deploy Rain and our white label apps to thousands of users across the United States. You will communicate efficiently with Product and Design to implement features at Rain's quality bar. If React Native + JavaScript/TypeScript is your passion — we want you.

- Implement pixel-perfect UIs and fluid, performant animations using Reanimated and modern theming libraries
- Architect robust data-handling patterns using RESTful APIs, React Query, and sophisticated state management (Redux, MobX, or Context API)
- Own the full release lifecycle, from managing App Store Connect and Google Play Store to maintaining CI/CD pipelines via Bitrise, Expo/EAS, or GitLab
- Work closely with designers, PMs, and backend engineers in a cross-functional environment to turn product visions into reality
Who You Are:
- You have 5+ years of professional mobile development experience under your belt
- You thrive with minimal supervision and can take ownership of complex features from ideation to deployment
- You are committed to code health, leveraging unit and integration testing to ensure a stable user experience
- You are forward-thinking and incorporate AI agents (like Cursor or Claude Code) into your workflow to increase velocity and code quality
- A natural problem-solver who can navigate complex debugging sessions using React Native Debugger or Chrome DevTools
Required Technical Qualifications:
- Expert-level knowledge of React Native (fundamentals and lifecycle) and TypeScript/ES6+
- Significant experience with React
- Proficiency with Reanimated; experience with Shopify Restyle is a plus
- Competency in native mobile languages (Swift, Objective-C, Kotlin, and/or Java)
- Hands-on experience with Jest and React Native Testing Library
- Familiarity with mobile-specific CI/CD workflows and automated build tools
Compensation:
