About The Role

As a Headless CMS Developer at Mercor, you'll own and evolve the content infrastructure powering mercor.com.

• Build, maintain, and extend Sanity CMS schemas, studio configurations, and content pipelines.
• Collaborate with design and product teams to translate content requirements into clean, structured data models.
• Develop and manage GROQ queries and Sanity APIs to surface content across the site.
