Software Engineer 2

Join Microsoft AI (MAI), the team behind Copilot, Bing, MSN, Microsoft Advertising, and Edge, as we build the next generation of intelligent mobile experiences. We’re looking for a Software Engineer with deep expertise in iOS development to support our mobile foundations. In this role, you will architect, harden, and optimize the core layers of our mobile applications—frameworks, infrastructure, performance pipelines, and reliability systems—that power Copilot and our broader ecosystem across millions of devices. This position is ideal for someone who thrives at the intersection of platform engineering, system design, performance optimization, and long-term architectural thinking. You will shape the technical backbone that enables product teams to move faster, ship safer, and innovate with confidence. If you enjoy building durable foundations, eliminating systemic risks, and raising the quality bar for mobile engineering, you’ll feel right at home on our team. MAI operates with the agility of a startup—fast-paced, iterative, and impact-driven—while backed by Microsoft’s mission to empower every person and organization on the planet to achieve more. We value engineers who take initiative, navigate ambiguity with clarity, and continuously push the boundaries of what mobile platforms can achieve.
