About The Position

Chrysalis is a privacy-first identity infrastructure company for the age of AI. We’re building a breakthrough AI platform and are looking for specialists in large-scale memory and graph systems to join at the ground floor.

You'll own the architecture and ensure our system can scale from the current stage to millions of users. This is a ground-floor opportunity with significant equity, technical autonomy, and the chance to shape a novel approach to identity infrastructure.
