Senior iOS Engineer

We are seeking a Senior iOS Engineer to own the client side implementation of how members join, pay, and stay with Raya. Member Experience owns the full member lifecycle - applying, onboarding, payments, and lifecycle management - and this role owns the surfaces where that lifecycle becomes revenue: the paywall, the purchase experience, and the subscription state a member sees in the app. This is a payments specialist role, not a generalist iOS role with some payments attached. The person we hire has built and operated native Apple StoreKit2 integrations more than once, with total depth and ownership - they wrote the integration, shipped it, and were still there when the edge cases showed up. They also bring production Stripe experience for a consumer product. They will work as a close peer to our server team, which owns App Store Server Notifications V2, entitlement source of truth, and reconciliation. Responsibilities: 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.
