About the Team The Monetization team is a new cross-functional group working across engineering, product, research, and design to build the foundational systems that will help OpenAI scale access to intelligence responsibly. Our mission is to develop user-first, privacy-preserving monetization products, including next-generation ads experiences that strengthen user trust, unlock economic opportunity, and support OpenAI’s long-term innovation. Monetization plays a critical role in enabling OpenAI to continue pushing the boundaries of AI capabilities while ensuring the benefits of AGI are broadly shared. We believe monetization must be aligned with user value, uphold rigorous privacy and safety standards, and sustain a healthy ecosystem of developers and businesses. This team operates in a greenfield environment and moves quickly through prototyping, experimentation, and iterative deployment. We partner closely with Product, Design, and Research to bring research breakthroughs into real-world systems at global scale. About the Role We’re looking for a Senior Android Engineer on OpenAI’s Applied team to build the core mobile experiences that power how users sign up, manage their account, use family features, pay for services, stay safe, and interact with OpenAI’s products with confidence.

Own complex Android systems end-to-end across UI architecture, networking, local persistence/state, observability, and release processes. Build robust integrations with Android platform and ecosystem components (e.g., Google Play Billing, authentication, device security signals, deep links, push). Optimize performance, reliability, and responsiveness at global scale (startup time, rendering, network resiliency, battery, crash-free sessions). Establish and evolve testing and quality systems (unit/integration/UI tests, CI reliability, automated regression, release validation). Collaborate with Product, Design, Research, backend, and Safety to deliver features 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 the Android foundations surface. 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 reliability- and trust-sensitive flows like identity and payments). Are fluent in Kotlin and comfortable with Android tooling and architecture (Gradle, Android Studio, modern app architecture patterns, Jetpack Compose). Enjoy making pragmatic architectural tradeoffs while keeping systems maintainable, testable, and scalable. Care deeply about performance, security, 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.
