Next-generation machine learning infrastructure.

Citadel AI builds software products to test and monitor high-risk AI systems. Our mission is to make the world’s AI systems more reliable and trustworthy.

We’re located in Tokyo, but we have an international team and global customers. Our goal is to build a world-class startup from Japan, and our team members have previously worked at leading companies such as Google, Waymo, Paidy, Toyota, Apple, and Stripe.

This is a unique opportunity to build new products for a global market from Tokyo. As Citadel AI’s first solutions engineer, you’ll have significant impact and ownership over the growth of our startup. We raised a Series A last year from Japan’s top investors, and are currently scaling our business in the 1 → 10 stage.
