AIML - Data Scientist, Evaluation

Overview

Do you get excited by driving product impact via measurement and evaluation, for products and services used by hundreds of millions of people globally? The AIML Evaluation organization uses data as the voice of customers to improve products. The Data Science and Insight team informs product evolution through measurement, evaluation, and analysis of the user experience. You will partner with Apple Intelligence engineering teams to improve product quality and guide feature development with data, delivering experiences across iPhone, iPad, Home Pod, Mac, Apple Watch, Apple TV, and dozens of languages.

Research and develop evaluation methods to improve the quality of Apple Intelligence user-facing products. Collaborate with evaluation/experimentation engineering teams to translate methodological developments into technologies used by Apple Intelligence engineering.

• Design and Own End-to-End Evaluation Frameworks:
  Develop rigorous evaluation methodologies for AI/ML systems, including metric definition, sampling strategy, experiment design, and statistical validity checks. Build scalable pipelines that ensure trustworthy, reproducible, and interpretable results across product surfaces and model iterations.
• Build High-Quality Evaluation Datasets & Human-in-the-Loop Systems:
  Create and maintain gold-standard datasets for offline and online model assessment. Lead data generation and annotation workflows (e.g., human ratings, Red Teaming, preference data, domain-specific evals), ensuring coverage, data quality, bias mitigation, and alignment with product and safety goals.
• Partner Cross-Functionally to Drive Model & Product Decision-Making:
  Translate evaluation insights into actionable recommendations for model training, ranking, and product launches. Collaborate with Research, Engineering, Product, and Safety teams to define quality bars, monitor regressions, optimize user experience, and guide roadmap prioritization.
