Machine Learning Engineer - Speech & Multimodal Language Modeling

Summary

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 features that leverage the
multimodal capabilities of state-of-the-art foundation language models. We are looking for a
highly skilled Machine Learning Engineer to build and evaluate these experiences, with a
specific focus on Multimodal and Speech Language Models. A successful candidate is
experienced in evaluating complex foundation model-driven systems end-to-end, translating
subjective product requirements into objective criteria, has strong statistical analysis skills, and
has worked with Speech Language Models.
