[OpenNash Jobs](https://jobs.opennash.com/) / [Apple](https://jobs.opennash.com/companies/apple/) / ML Data & Eval Engineer, Siri Agent Modeling

## Job description

The frontier of AI isn't in the cloud anymore. It's in your pocket. Every model that runs on a user's device depends on a lot of systems behind it: data pipelines that decide what it learns, infrastructure that trains and evaluates it at scale, and tooling that gets it efficiently onto Apple silicon. At Apple's Siri team, we're building the next generation of agents and deploying them at the largest customer scale in the world.

We're looking for generalist engineers who like working across the whole ML lifecycle. You might build a data pipeline one quarter and a training platform the next, wherever the biggest bottleneck is. This role is for builders who want end-to-end ownership of the data and infrastructure behind frontier on-device ML, from raw data to silicon.
