Senior Sanity + Next.js Developer (Remote - LATAM)

About the role

WorkO3 World, a Philadelphia‑based digital consultancy, is looking for a senior developer to help deliver a large headless‑CMS migration and ongoing feature work. The role is fully remote, focused on LATAM candidates, and runs on a 30–40 hour weekly contract.

Key responsibilities

• Design and implement Sanity schemas, including document types, objects, references, and Studio configuration.
• Build Next.js front‑ends that consume those schemas, using GROQ queries, caching, and on‑demand revalidation.
• Develop and run migration pipelines from legacy CMS platforms (e.g., Umbraco, WordPress, Drupal) into Sanity, handling HTML‑to‑Portable Text conversion.
• Maintain redirect maps for large‑scale migrations and fill gaps in existing content models.
• Translate Figma designs into production‑ready, responsive, and accessible components.
• Leverage AI coding agents to scaffold components, generate schemas, and automate repetitive scripts.
• Set up project instruction files, conventions, and reusable prompts to make AI assistance effective for the team.
• Participate in code reviews, sprint ceremonies, and client‑facing technical discussions as needed.

Required profile

• Proven production experience with Sanity, especially schema design and Studio configuration.
• Strong expertise in Next.js (App Router, server components, modern data‑fetching patterns).
• Solid TypeScript and React skills.
• Hands‑on experience migrating content from legacy CMSs at volume.
• Ability to write reusable ETL scripts (Node.js) and make them re‑runnable.
• Comfort reading Figma files and implementing designs without exhaustive specifications.
• Clear written communication for asynchronous coordination.
