Sr. Health AI Software Engineer

Sunnyvale, California, United States Software and Services

Apple builds products that enrich lives by making powerful technology feel simple, intuitive, and accessible. Through deep integration of hardware, software, services, and design, we deliver end-to-end experiences that fit naturally and seamlessly into everyday life. Nowhere is this mission more vital than in Health, where we have the opportunity to build ambitious features that can change, or even save, lives.

We’re looking for software engineers to help us develop ambitious, high-impact features that harness the power of health data, AI, and other enabling technologies to help millions of people live healthier lives—all built on a foundation of uncompromising privacy and security.

As a Health AI Engineer, you will architect and implement features that bring the power of generative AI to Apple’s health sensors and data to help people improve their health & wellbeing. In this role, you will work across the stack, from the system software that processes sensitive health data to delightful user interfaces that help people live healthier lives. This is a highly cross‑functional role, working closely with clinical, design, algorithms, software, privacy, security, performance, and sometimes even HW/Silicon teams across Apple to engineer end‑to‑end solutions.

You will need to work quickly and creatively to help demonstrate the viability of ideas and technologies while building robust, production‑ready systems that millions of users will depend on. You will need to be comfortable writing Swift code, evaluating AI/ML algorithms for on‑device integration, collaborating on user experience design, debugging complex cross‑device interactions, and contributing to a culture of shipping high‑quality production code.

In addition to software engineering, you will also apply excellent UX intuition to identify and shape experience opportunities, iterate with clinical & design, and define technical requirements that drive development.

• BS / MS / PhD in Computer Science or equivalent experience in related field
• 5+ years in software development
• Excellent programming skills in any programming language (preferably at least one of in Swift and/or Objective‑C, C++) and strong understanding of data structures, memory management, and concurrency
• Skilled at debugging and triaging software defects including race conditions, deadlocks, synchronization issues in multi‑threaded environments etc.
• Systems thinking, including ability to break down ambiguous problems and drive clarity on critical details
• Strong intuition for user experience + ability to translate customer needs into technical requirements
• Solid cross‑functional collaboration and technical communication skills

• Shipping customer‑facing features — particularly for health, fitness, or wellness - to production at scale
• Developing for iOS/MacOS and/or using Apple frameworks like Swift
  
  UI, Health Kit, Research Kit, or ARKit
• Developing health or personalization features, including working with clinicians, writing software for Health data / other sensitive data sources, and validating performance/impact over population
• Building & shipping features using LLMs and/or Machine Learning algorithms, including on‑device inference, data‑driven validation, requirement definition, and collaboration with algorithm teams
• Processing sensor data, (e.g. image/video, audio, motion), such as using computer vision or signal processing
• Developing under strict privacy and security constraints, including techniques like secure data processing, and/or privacy‑by‑design principles
• Developing system software or frameworks, including API definition and performance optimization (particularly for resource constrained or real‑time systems)
• Working with distributed systems and modeling data that easily synchronizes across an ecosystem of devices.
