About the Team
You'll be the lead iOS engineer at Rain, owning mobile alongside the lead Android developer from the ground up. Our partners use Rain's issuance platform and APIs to power card programs, wallets, and payment experiences for their end users, and you'll be the person who brings those experiences to life on iOS. You'll work directly with product, design, and our platform engineering team to define what great mobile looks like for Rain's clients and their customers.
What you’ll do
Own the entire iOS development lifecycle, from architecture and implementation to App Store delivery
Build polished, production-grade mobile apps that leverage Rain's issuance platform and APIs for clients and their end users
Collaborate closely with product, design, and backend engineers to define the mobile roadmap and translate platform capabilities into intuitive native experiences
Architect a clean, scalable codebase that can serve as the foundation as the mobile team grows
Integrate with Rain's APIs for card issuance, transaction management, balance queries, and other payment flows
Implement secure authentication, tokenization, and data handling appropriate for a financial services context
Drive decisions on tooling, frameworks, CI/CD, and testing strategy for mobile
Contribute to the broader engineering culture as an early team member with outsized influence on how we build
You are likely to succeed if you have:
4–10 years of professional mobile development experience, with multiple apps shipped to the App Store
Proficiency in Swift and deep familiarity with Apple's frameworks (UIKit, SwiftUI, Combine, Core Data, etc.)
Experience architecting iOS apps from scratch. You've made foundational decisions on project structure, navigation patterns, state management, and dependency injection
Solid understanding of networking layers, RESTful API integration, and secure data handling
A disciplined approach to code quality: you write testable code, value code review, and care about maintainability
Comfort working autonomously with minimal direction — you'll be the mobile expert in the room
Strong product sensibility: you think beyond tickets and advocate for great user experiences
Excellent communication skills; you can translate technical tradeoffs for non-technical stakeholders
Bonus attributes:
Experience in fintech, payments, or crypto/web3
Familiarity with card issuance, wallet UX, or financial transaction flows
Experience with WKWebView-based hybrid architectures or embedded SDK patterns
