Machine Learning Engineer - Crowdsourced Sensing

The Sensing and Connectivity team is committed to developing innovative technology that enhances user safety and makes our devices more intelligent. We are exploring how the incredible sensing, processing, and connectivity of iPhone can be leveraged to detect nearby hazards and deliver timely alerts. We are seeking a Machine Learning Engineer to own the design, deployment, and operation of ML models that run across heterogeneous mobile and edge devices. In this role, you will build production ML systems end-to-end including feature design, training, on-device inference, monitoring, and continuous improvement based on real-world telemetry.

Description

As a Machine Learning Engineer on the crowdsourced sensing team, you will develop, deploy, and maintain machine-learning models that operate reliably in noisy, real-world environments and at global scale.","responsibilities":"Own ML models end-to-end, including feature design, training, evaluation, deployment, and iteration based on live telemetry

Design and implement low-latency, resource-efficient inference pipelines for on-device and edge-constrained environments

Build simulation, replay, and regression frameworks to evaluate model performance under real-world conditions

Analyze large-scale, real-time sensor telemetry to detect model degradation, bias, and distribution shift

Define and track model-level metrics (accuracy, latency, power, memory) and implement monitoring and rollback strategies

Collaborate closely with hardware, firmware, data engineering, and software teams to prototype new capabilities and ship production-quality ML systems to millions of devices worldwide

Preferred Qualifications

Experience with real-time and/or large-scale data processing tooling (e.g. Kafka, Flink, Spark, etc.)

Experience with sensor networks, IoT systems, or mobile sensing

Experience with inertial sensing, time series analysis, signal processing, system identification

Experience with multi-sensor fusion (accelerometer, gyroscope, barometer, GNSS)

Experience monitoring ML systems in production, including drift detection, regression analysis, and iterative retraining

Minimum Qualifications

Graduate degree in Computer Science, Data Science, or equivalent experience.

5 years of experience with ML training frameworks (e.g., PyTorch, TensorFlow) and model evaluation methodologies

5 years of experience designing and deploying machine-learning models in production systems

3 years of experience handling noisy, heterogeneous, crowdsourced sensor data

3 years of experience designing and deploying ML models on resource-constrained devices
