Machine Learning Engineer - On-Device Adaptive Control

The Energy Tech org builds systems for managing the energy flow and thermals of Apple devices in service of a great user experience. Within this org, the team develops end-to-end solutions utilizing on-device machine learning and control, creating new techniques from data analysis and prototyping. Our work directly impacts the behavior of Apple devices across the product families. We are developing on-device control systems that manage thermal and energy tradeoffs on Apple devices. This means building models that capture device dynamics, designing cost functions that encode explicit priorities, and shipping control loops that adapt to real-world conditions. Were looking for a Machine Learning Engineer who can work across the full stack: analyzing field data to understand device behavior, prototyping control and ML algorithms, and getting them running on-device. The problems are messy - noisy sensors, changing hardware, competing objectives - and the solutions need to be simple enough to ship on constrained hardware.Design and implement on-device control systems for thermal and energy management Build and fit thermal models from lab and field data Prototype MPC and related control algorithms end-to-end, from data analysis through on-device deployment Analyze large-scale field telemetry to characterize device behavior and validate models Define and tune cost functions that encode system-level tradeoffs Collaborate with firmware, hardware, and platform teams to integrate control systems into the OSMS or PhD in controls, robotics, electrical engineering, computer science, or related field - or BS with relevant experience Experience with model predictive control, optimal control, or reinforcement learning (sequential decision-making) Strong programming skills in Python; comfort with C/C++ for on-device work Experience working with real-world sensor data (noisy, incomplete, high-volume) Demonstrated ability to take a project from data exploration through working prototypeExperience with thermal systems, battery management, or energy optimization Familiarity with embedded or resource-constrained environments Background in system identification or online parameter estimation Comfort with ambiguity - able to scope and drive work without detailed specifications Track record of shipping models or control systems into production, not just research
