Senior Swift Software Engineer - Agentic OS Experiences

We're a small team at Apple betting on what comes next. We believe AI will fundamentally change how people interact with their devices — and we're looking for software engineers who want to build that future. We can't say much about what we're building for our customers. What we can say: the problems are genuinely new and the potential reach is enormous. Beyond the work, we're a collaborative, humble, and curious group that loves learning from each other and building together. ## Description You'll work alongside a tight group of engineers, designers, and researchers to bring AI features from early prototype to product. This is 0-to-1 work — from a rough idea on a whiteboard to software running on real devices. You'll have a lot of autonomy in how you get there. ## Responsibilities Building AI-powered experiences — whether that's crafting new iOS interactions, designing agentic systems that orchestrate tools under the hood, or both Prototyping rapidly to explore what works — then making it real Partnering with Design, ML, and AI researchers to shape features and translate cutting-edge models into tangible experiences — not just implement specs Driving architecture decisions and raising the quality bar through technical leadership Investing in the quality and reliability of what you ship — through testing, tooling, and infrastructure that gives the team confidence ## Minimum qualifications 5+ years of mobile or application development experience, strong CS fundamentals, iOS and Swift experience is a plus — but if you're strong in another platform, you'll ramp quickly here You've shipped software that people relied on, and you learned something from every hard call along the way You're someone who unblocks yourself. When the path isn't clear, you figure it out — whether that means reading the source, building a prototype, or pulling in the right people Comfortable with ambiguity and excited by problems that don't have an obvious answer yet You work well across teams and build trust with partners in design and engineering You make the people around you better — through mentoring, shaping technical direction, and the way you approach hard problems You've already brought AI into how you write code — and you're always looking for the next way to use it B.S. Computer Science or equivalent experience required ## Preferred qualifications Deep experience in one or more iOS/macOS domains: system services, UI frameworks, concurrent application architecture, or performance optimization You've wired together LLM-powered systems yourself — agents, tool orchestration, prompt engineering — and you have opinions about what worked and what didn't Close to the frontier. You're the person your team comes to when a new model drops or a new technique emerges A sharp eye for detail. You notice what's off and you know when it's right A point of view on where human-AI interaction is headed — and the instinct to know what it should feel like when it gets there
