Senior Sanity Engineer (AEM Sanity Migration)

To ensure a fair and efficient hiring process, candidates should not contact UN/COMMON employees directly regarding this role. Applications and communication must occur through the official application process.
We are seeking a Senior Sanity Engineer to Lead the technical migration from AEM to Sanity CMS. This is a lift-and-shift rebuild of existing content architecture — not a redesign — requiring strong experience in schema modeling, content migration, and headless CMS integrations.

This role will own the technical implementation of Sanity Studio, content modeling strategy, migration scripting, and integration with a Shopify/Hydrogen frontend.

This is not a traditional AEM backend role. We are specifically looking for deep, hands-on Sanity expertise.
