Data Scientist - Survey Design, Data Annotation, and Machine Learning Evaluation

Apple is where individual imaginations gather together, committing to the values that lead to

great work. Every new product we build, service we create, or experience we deliver is the

result of us making each other's ideas stronger. The diversity of our people and their thinking

inspires the innovation that runs through everything we do. When we bring everybody in, we

can do the best work of our lives. Here, you'll do more than join something - you'll add

something.

Description

The Special Projects team at Apple is developing novel user-facing conversational features that

leverage the multimodal capabilities of state-of-the-art foundation models. As part of this

process, we generate real-world and simulated data, gather human data annotations, analyze

the results, and use them to build and evaluate Large Language Model judges. We are looking

for a skilled Data Scientist to join our Machine Learning Evaluations teams. This person will

work closely with ML Engineers to manage and analyze our human and automated data

annotation processes, and to develop, test, and refine LLM judges for generative AI model

evaluation. A successful candidate is experienced in survey design, data annotation, LLM

prompt engineering and prompt optimization, and has strong statistical analysis skills.

Minimum Qualifications
