AIML Software Engineer, On-Device Audio Intelligence, Sensing & Connectivity

Cupertino, California, United States$184,700 - $277,6006+ years

In Sensing & Connectivity, we use on-device sensors and wireless technologies to understand user context — combining sensor data with machine learning to create intelligent, ambient experiences across Apple platforms. As a Software Engineer on the Location & Motion team, you will design and build the frameworks and system services that enable on-device sensing at scale. You will create algorithms that process real-time signals, extract meaningful context, and deliver those insights to users through platform-level frameworks and integrations with Apple Intelligence. You'll work closely with CoreLocation, CoreMotion, Audio Understanding, and AIML colleagues to tackle open-ended, research-like problems — prototyping novel sensing capabilities and bringing them to production on Apple platforms.

This role is for the platform-level work: daemons, frameworks, and ML inference pipelines beneath the UI layer, continuously interpreting the environment efficiently, privately, and deeply integrated with the OS. You will collaborate with ML researchers to translate models into production systems. Problems span low-level signal capture to high-level context modeling to APIs surfacing capabilities to developers and features across Apple platforms.

Audio feature extraction or classification pipelines for on-device ML
Experience training/fine-tuning ML models or collaborating with ML researchers to productionize them
Deep OS stack debugging (frameworks, daemons, services)
Energy efficiency and resource constraint optimization on mobile
Privacy-preserving sensing (on-device inference, data minimization)
CloudKit or distributed data sync
Public or internal API/SDK design and delivery
Mentorship and technical direction track record
