iOS Software Engineer, Siri Home Devices

About the position Siri handles billions of interactions across Apple's devices, and Apple Intelligence is redefining what people expect from those moments. This is an unusual time to join: the product is evolving fast, the bar is rising, and there's real opportunity to shape what comes next. On the Siri Devices team, we own the Siri platform and end-user experience on Apple's devices—both the on-device UI people interact with and the iOS frameworks and system integrations that power it. You'll ship work that reaches millions of people across Apple devices worldwide. This role is based in Pittsburgh (hybrid: 3 days onsite, 2 days flex). Apple will cover relocation for candidates moving here. You'll craft the Siri experience, from UI down to the frameworks and services that power it—making it feel fast, reliable, and natural. What you'll do Build and ship user-facing Siri experiences using UIKit and SwiftUI. Develop and maintain iOS frameworks and components that enable Siri UX across the system. Debug issues that cross app, framework, and system boundaries using logging, instrumentation, and performance tools (e.g., Instruments). Improve responsiveness, reliability, and polish through measurable gains. Partner with teams across the Siri stack—Experiences, Orchestration, Knowledge/Answers, System Experience, and Apple's apps teams—to drive work to completion. How you'll grow You'll start with well-scoped work and strong support: design reviews, pairing sessions, and code review from senior engineers who know the platform deeply. As you ship and build judgment, you'll take on broader ownership—larger features, architectural contributions, and more open-ended problems. This team has a track record of growing engineers into senior roles. You'll get exposure to how the full Siri stack fits together and the kind of complex, cross-functional work that accelerates careers. You might thrive here if You seek out feedback and incorporate it quickly. You ramp into new systems fast and enjoy learning large codebases. You can make progress when requirements evolve and you ask good questions early. You take ownership of outcomes, not just tasks, and follow through. You communicate clearly and directly, especially when something is uncertain. Technology We use Swift and Objective-C; new development is primarily Swift. You don't need Objective-C expertise, but you should be comfortable learning and contributing in a mixed codebase. Life in Pittsburgh Pittsburgh has an energized tech scene and is genuinely easy to live in: distinct neighborhoods, great food, rivers and trails, and more time back in your day.
