Software Developer, Software Engineer, Software Architect

Apple builds products that enrich lives, and at the heart of those experiences is world‑class software. The Sensing Software team is seeking an outstanding Software Developer to help drive the software development and architecture underlying next generation Apple products. In this role, you will shape foundational application and system architectures across iOS, watch

OS, and emerging platforms, collaborating deeply with cross‑functional hardware, algorithms, data engineering, and product design teams. You will leverage your expertise in large‑scale system design, performance optimization, and Apple’s software frameworks to build robust platforms that power novel sensing and research experiences. This is a highly visible, highly technical role requiring strong technical leadership, clarity of thought, and the ability to influence technical direction across teams!

In this role, you will lead architectural efforts across current and future Apple sensing and research software platforms. You will partner with hardware, algorithms, and multi‑functional engineering teams to define the application and system software layers that support groundbreaking features and data‑driven experiences.

• Driving end‑to‑end architecture for iOS applications and internal research platforms
• Help establishing coding standards, architectural patterns, and platform roadmaps.
• Building modular, scalable, and testable components enabling research studies, sensor pipelines, and future product features.
• Supporting product teams and prototyping teams through rapid iteration cycles.
• Guiding engineers through design reviews, code reviews, and architectural decisions.
• Profiling and optimizing for performance, power, reliability, and data integrity.
• Collaborating closely with cross‑functional partners to bring new hardware and sensing capabilities to life.
• Contributing to the vision of next‑generation software platforms at Apple.
