OpenAI • San Francisco, CA

About The Position

We’re looking for a Senior iOS Engineer to build the core mobile monetization experiences and iOS foundations that power how users sign up, manage their account, access family features, pay for services, and interact with monetized experiences safely and confidently across OpenAI’s mobile apps.
This is a 0→1, greenfield opportunity: you’ll help define the architecture, primitives, and reusable frameworks that product teams depend on to ship quickly while meeting the highest standards for security, reliability, privacy, and user trust. You’ll partner closely with backend, product, design, safety, and research to translate evolving requirements into high-quality iOS systems and experiences.

Requirements

• Have 4+ years of professional software engineering experience with significant iOS ownership.
• Have a proven track record shipping high-quality iOS apps in production for business-critical, reliability-sensitive systems.
• Are fluent in Swift and experienced with Apple’s ecosystem (Xcode, UIKit, SwiftUI); you can choose the right tool for the job and evolve codebases pragmatically.
• Have owned complex mobile systems end-to-end (architecture, delivery, instrumentation, quality, and operations).
• Care deeply about performance, security, privacy, and user experience, especially in flows involving identity and payments.
• Thrive in 0→1 environments where systems, architecture, and user experiences must be defined from scratch.

Responsibilities

• Build and ship new monetization experiences on iOS, including purchase flows, subscription/plan management, and monetization-adjacent surfaces that showcase the power of AI.
• Design and maintain shared iOS frameworks and primitives for account, trust, and commerce flows used across OpenAI’s mobile apps (e.g., identity, entitlements, payments, policy-aware UX).
• Own complex client-side systems spanning UI, networking, local state, observability, and Apple platform integrations (StoreKit, Sign in with Apple, device security primitives, etc.).
• Optimize performance, reliability, and responsiveness for global-scale usage, including robust offline/poor-network handling and safe rollout strategies.
• Establish and evolve testing frameworks (unit, integration, snapshot/UI, and end-to-end) and refine architecture for long-term maintainability.
• Collaborate deeply with Product, Design, Research, and backend teams to translate ambiguous goals into durable systems and delightful experiences.
• Help uphold the highest levels of safety, privacy, fairness, and policy compliance across monetization experiences.
• Provide technical leadership through architectural reviews, mentoring, and setting engineering standards across iOS monetization foundations.
