About the Team The Consumer Devices team is building a new generation of AI-native experiences that bring OpenAI’s technology closer to people throughout their day. We are exploring how AI can become deeply integrated into the devices people already use—understanding context, helping users accomplish tasks, coordinating across apps and services, and making use of capabilities that are uniquely available on the device. Our work spans software, devices, platform technologies, and strategic partnerships. We operate as a highly collaborative, fast-moving team focused on turning ambitious ideas into reliable products that can reach people at significant scale. About the Role As an Android Systems Engineer , you will help define and build the Android platform capabilities behind the next generation of AI-powered consumer experiences. This is not a traditional application-only Android role. You will work across the Android stack, using system-level APIs, device capabilities, platform integrations, and OEM-specific functionality to create experiences that would be difficult or impossible to build as a conventional mobile application. You will help determine what becomes possible when an AI assistant is deeply integrated with a mobile device: how it understands what is happening, interacts naturally with the user, connects across apps and services, and helps complete multi-step tasks. You will work closely with product, design, AI, backend, platform, and external device partners to take new concepts from prototype to production. The role requires strong technical judgment, product intuition, and comfort navigating areas where the platform, APIs, and product patterns are still evolving. This role is based in San Francisco, CA. We use a hybrid work model of four days in the office per week and offer relocation assistance to new employees.

About the Team The Systems Integration team is responsible for building the infrastructure, tooling, and validation systems that ensure our device software our device software is reliable, testable, and ready to ship. We design and maintain build systems, CI pipelines, automated test frameworks, and hardware-in-the-loop labs to enable rapid, safe product launches. Our work spans build systems, developer tools, systems integration, and cross-team collaboration to ensure developers can build reliably and ship with confidence. About the Role We are looking for an engineer to help evolve OpenAI’s Consumer Products build and continuous integration systems for a fast-growing engineering organization. This role sits at the intersection of developer productivity, build systems, distributed infrastructure, software quality, and on-device software. You will work on the systems that determine how quickly and confident engineers can move: Bazel-bazed builds, Buildkite pipelines, test coverage, remote caching and execution, CI observability, and tooling that helps engineers understand and fix failures quickly. Our mission is to enable OpenAI to ship software running on consumer devices rapidly with a high bar for correctness, reliability, and safety. The best version of this work is invisible when it succeeds: builds are fast, tests are trusted, CI failures are understandable, and engineers can focus on shipping products instead of fighting infrastructure. This role is based in San Francisco, CA. We use a hybrid work model of four days in the office per week and offer relocation assistance to new employees. In This Role, You Will Own and evolve Bazel and yocto-based build and test workflows in a polyrepo environment Design and maintain Starlark rules, macros, toolchains, and integrations that make builds hermetic, reproducible, and easy for teams to adopt Improve CI performance and reliability across Buildkite pipelines, including queue time, build time, cache hit rates, retry b
