As Microsoft continues to push the boundaries of AI, we are on the lookout for passionate individuals to work with us on the most interesting and challenging AI questions of our time. Our vision is bold and broad — to build systems that have true artificial intelligence across agents, applications, services, and infrastructure. It’s also inclusive: we aim to make AI accessible to all — consumers, businesses, developers — so that everyone can realize its benefits. We are looking for a Build Engineer to design and improve the systems that transform source code into reliable, production-ready artifacts. This role focuses on build systems, CI pipelines, and developer workflows to ensure fast, reliable, and reproducible builds across our engineering organization. You will work closely with product engineers, platform teams, and infrastructure engineers to improve the efficiency and reliability of our development lifecycle. Build and release engineers play a critical role in the software lifecycle by defining the steps required to build, test, package, and release software reliably across environments.
