iOS Engineer, Ad Formats

Team

Join OpenAI's Monetization team, a new cross-functional group building foundational systems to scale access to intelligence responsibly. You'll help build native iOS experiences and client-side systems for next-generation ads formats (text, image, video, native, conversational, interactive) across OpenAI surfaces, including integration into the core ChatGPT experience.

Responsibilities

• Build and ship ads format experiences on iOS, including text, image, video, native, conversational, and interactive ad surfaces
• Design and maintain shared iOS frameworks and primitives for ad rendering, creative presentation, media handling, format validation, and policy-aware UX patterns
• Own complex iOS systems end-to-end across UI architecture, networking, local persistence/state, observability, rendering performance, and release processes
• Build robust integrations with Apple platform components: media playback, deep links, app lifecycle behavior, accessibility, privacy controls, and device capabilities
• Optimize performance, reliability, and responsiveness at global scale: rendering quality, scrolling performance, startup time, media load latency, network resiliency, battery usage, crash-free sessions
• Establish and evolve testing and quality systems: unit, integration, snapshot/UI, automated regression, release validation workflows
• Collaborate with Product, Design, Research, backend, and Safety to deliver ads experiences meeting safety, privacy, fairness, and policy compliance standards
• Provide technical leadership through architecture reviews, mentoring, and setting engineering standards

Requirements

• 4+ years of professional software engineering experience with significant iOS ownership
• Proven track record shipping high-quality iOS applications in production, especially for user-facing, performance-sensitive, or trust-sensitive experiences
• Fluent in Swift and experienced with Apple's ecosystem (Xcode, SwiftUI, UIKit, modern iOS architecture patterns)
• Owned complex mobile systems end-to-end across architecture, delivery, instrumentation, quality, and operations
• Experience building polished mobile UI systems, media-rich experiences, rendering frameworks, design systems, or reusable product infrastructure
• Makes pragmatic architectural tradeoffs while keeping systems maintainable, testable, and scalable
• Cares deeply about performance, reliability, privacy, and user experience with a high bar for polish
• Thrives in 0→1 environments where systems, architecture, and user experiences must be defined from scratch
