Data Scientist - Battery

Cupertino, California, United States Hardware

Do you have a passion for invention and self-challenge? Do you thrive on pushing thelimits of what’s considered feasible? As part of our Battery Engineering group, you’llhelp craft creative battery solutions that deliver more energy in smaller spaces thanever before! We work across subject areas to transform improved hardware elements into a single, integrated design. Join us, and you’ll help us innovate new batterytechnologies that continually outperform the previous iterations.

By collaborating withother product development groups across Apple, we push the industry boundaries ofwhat batteries can do and improve the product experience for our customers across theworld! This position works within a multi-functional team supporting the entire Battery Department to identify trends, mine data, and help the battery team improve performance.

The Battery Analytics team transforms data into actionable insights by combining deep battery domain expertise with statistical, quantitative, and AI/ML methodologies.

• Analyze multi-source data (factory, laboratory, field, and failure data) and collaborate with cross-functional teams to resolve battery performance issues
• Navigate Apple's database ecosystem to efficiently extract representative datasets while maintaining data quality standards for data-driven analysis
• Design and implement robust data processing workflows; apply advanced modeling techniques with emphasis on causal analysis leveraging battery physics knowledge
• Build comprehensive time-series and battery cycling data visualization and analytics capabilities
• Conduct comparative studies, identify early warning signals, and lead failure analysis deep-dives
• Drive resolution of anomalous forecasts for critical KPIs including battery swell, impedance, and capacity fade
• Develop AI/ML capability for battery engineering leveraging state-of-the-art GenAI progress

• BS degree in Mechanical Engineering, Material Engineering, Electrical Engineering, Computer Science or relevant
• Experience with statistical analysis, data mining, or relevant

• Master’s degree, PhD or equivalent job-related experience in Mechanical Engineering, Material Engineering, Electrical Engineering, Computer Science or relevant
• Proven experience in statistical analysis, data mining, and causal inference methodologies
• Advanced proficiency in big data processing, visualization, and automated workflow development using Python, R, or similar scripting languages
• Hands-on experience with machine learning algorithms including ensemble methods, probabilistic networks, association rules, clustering, regression, neural networks, and large language mode
• Strong analytical problem-solving abilities to address urgent ad-hoc requests by integrating engineering knowledge with advanced analytics and ML techniques across diverse data sources
• Demonstrated expertise in anomaly detection techniques for time series and multivariate dataset
• Self-motivated contributor who proactively collaborates across functions and develops innovative solutions beyond existing toolsets
• Excellent communication skills with ability to explain complex technical concepts (particularly causal inference) to diverse audiences including data scientists, design engineers, and business stakeholders
• Battery technology experience strongly preferred
