## Description

The Applied AI team owns all of the systems and services that integrate AI into the NEO platform including supporting data infrastructure for the World Model Lab. They ship platform APIs that allow our developers to collect data for fine-tuning, deploy inference at scale, and integrate AI elsewhere in the robot software stack.

Your Charter

Build platform APIs for high-quality training data for our new world model. This will involve APIs for data validation, auto-captioning/annotation, and validation. You'll operate at high scale, support a wide variety of developers, and work closely with our internal World Model team to pretrain a new world model. You will also find opportunities to integrate AI in other systems elsewhere in the stack.

Key Outcomes

 * Design, build, and ship production features for AI world models, from data collection through inference
 * Build rigorous evaluation, data pipelines, and captioning APIs tightly integrated into simulators and robot hardware
 * Optimize systems for latency, cost, and quality
 * Work closely with world model researchers, product engineers, and customers to build systems that are reliable and easy to use
 * Stay current with new developments in AI and bring recommendations to the platform and research teams.
