Android Engineer, Ad Formats

About the Role

We’re looking for an Android Engineer to help build the native Android experiences and client-side systems that power how ads are structured, rendered, and delivered across OpenAI’s ads ecosystem. This role sits within the Ads Formats team, which owns the creative rendering and presentation layer for next-generation ads experiences across different surfaces and media types.

You’ll help build the Android infrastructure and tooling that support formats such as text, image, video, native, conversational, and interactive ads, while ensuring they render reliably and perform efficiently across platforms. You’ll work closely with backend, Product, Design, Research, and Safety partners to shape Android architecture that supports user-first, privacy-preserving monetization experiences within ChatGPT and OpenAI’s broader mobile ecosystem.

In this role, you will

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

You might thrive in this role if you

• Have 4+ years of professional software engineering experience with meaningful Android ownership.
• Have a track record of building and shipping high-quality Android applications in production, especially for user-facing, performance-sensitive, or trust-sensitive flows.
• Are fluent in Kotlin and comfortable with Android tooling and architecture, including Gradle, Android Studio, modern app architecture patterns, and Jetpack Compose.
• Have experience building polished mobile UI systems, media-rich experiences, rendering frameworks, design systems, or reusable product infrastructure.
• Enjoy making pragmatic architectural tradeoffs while keeping systems maintainable, testable, and scalable.
• Care deeply about performance, reliability, privacy, and user experience, and you bring a high bar for polish.
• Thrive in 0→1 environments where systems, architecture, and user experiences must be defined from scratch.
• Bonus: Have experience with ads formats, creative rendering systems, media delivery, native ads, conversational products, mobile monetization, or large-scale consumer mobile applications.
