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.
Requirements:
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
