Full Job Description
Description

Our team, part of Apple Services Engineering, is building the scientific foundation for how AI systems are evaluated across Apple. We are seeking a Measurement Scientist to ensure that our evaluation methods are not just sophisticated, but scientifically valid and trustworthy . In this role, you will apply psychometric theory , validity frameworks, and statistical rigor to establish measurement standards for AI evaluation - ensuring that when we claim an evaluator measures "helpfulness" or "safety ," it actually does. We are looking for individuals across a range of experience levels.

This role uniquely bridges measurement science and cutting-edge AI evaluation. You will develop methods for validating LLM-as-judge evaluators, automated benchmarks, and human evaluations. And you will create statistical tools that help engineers trust their evaluation results. You will work on an interdisciplinary team with ML researchers to solve new problems in AI evaluation. Your work will be both published at top measurement and ML venues and productionized into the evaluation SDK used across Apple.

The successful candidate will have deep expertise in psychometrics and measurement theory , with the ability to apply these principles to novel AI evaluation challenges. You will work collaboratively with ML researchers, platform engineers, and evaluation practitioners to translate measurement science into practical tools that scale across the organization.

Minimum Qualifications

PhD in Psychometrics, Educational Measurement, Quantitative Psychology , Statistics, or equivalent research/work experience.

Deep expertise in modeling test data (IRT or related methods) and construct validation.

Strong statistical foundation including experimental design, power analysis, sampling theory , and uncertaintyquantification.

Track record of designing and validating measurement instruments as demonstrated through publications or applied work.

Proficiency in Python (preferred) or R for statistical analysis, psychometric modeling, and method implementation.

Strong working knowledge of generative AI technology

Excellent communication skills with the ability to explain complex measurement concepts to engineers, ML researchers, and non-technical stakeholders.

Preferred Qualifications

Experience applying measurement science to AI/ML evaluation, automated scoring systems, or computational assessment.

Knowledge of modern ML evaluation challenges including LLM-as-judge, automated metrics, benchmark design, and agentic systems.

Publications at measurement venues or top ML conferences (NeurIPS, ICML, ICLR).

Expertise in computational social or behavioral science using generative AI

Experience collaborating with engineers to turn research methods into production tools and scalable infrastructure.
