•
Own the iOS subscription and payments stack end to end from product configuration, purchase and restore flows, entitlement state, offers, to the paywall surfaces members see.
•
Serve as the client-side authority on StoreKit2: architect the integration, set the patterns, and handle the lifecycle edge cases. Including interrupted and deferred purchases, upgrades, downgrades, crossgrades, refunds, revocations, billing retry, and price increase consent.
•
Partner closely with the server team on entitlement correctness, working across the client/server boundary on signed transaction verification, reconciliation, and idempotency so that what the app shows and what the backend believes never diverge.
•
Work with product, design, and data on pricing, offers, and paywall experimentation. Scoping and shipping revenue-affecting work from concept through launch and measurement.
•
Contribute broadly to a large, long-lived iOS codebase: architecture and system design, performance, testing practices, and deliberate management of tech debt.
•
Act as the client-side escalation point for member payment issues, with the monitoring and release discipline to catch problems before members do.
•
Raise the engineering bar through code review, technical mentorship, and clear written specs.
•
7+ years of professional iOS development experience, with strong proficiency in Swift, SwiftUI, UIKit, MVVM, and reactive programming.
•
Expert-level, hands-on Apple StoreKit2 experience: you have built and operated StoreKit2 integrations end to end at least twice in production, owning product configuration, purchase and restore flows, Transaction.updates, current entitlements and subscription status, introductory / promotional / win-back offers, offer codes, and sandbox-through-production testing.
•
Direct, native StoreKit2 integration experience and depth that goes beyond consuming a third-party abstraction layer. You can reason about the framework itself.
•
Production Stripe Payments/Subscriptions experience for a B2C product (secondary to Apple, but required).
•
Experience collaborating with a server team on subscription correctness including App Store Server Notifications V2, signed transaction verification, reconciliation, and idempotent handling of duplicate events.
•
A track record of building and shipping consumer mobile applications to scaled audiences, with strong judgment on architecture, performance optimization, and user experience.
•
Strong consumer product sense and the ability to partner effectively with product, design, and data on revenue-affecting work.
•
Proven ability to lead projects from concept through launch, balancing speed and quality, and to own what you ship after it ships.
•
An AI-forward mindset, with curiosity about applying emerging technologies to improve developer and product experiences.
•
Experience migrating a production app from StoreKit1 to StoreKit2.
•
Experience running a subscription product across two payment processors simultaneously, with a single active entitlement per member.
•
Familiarity with SwiftUI alongside UIKit, and with modularizing a large iOS codebase.
•
Experience with paywall and pricing experimentation frameworks, and with subscription analytics.
