About the role

WorkO3 World, a Philadelphia‑based digital consultancy, is looking for a senior developer to join its remote LATAM team on a short‑term contract. You will work directly with staff engineers to deliver real‑world projects involving Sanity CMS migrations, feature development, and client support.

Key responsibilities

• Design and implement Sanity schemas, document types, objects, references, and Studio configuration.
• Build Next.js front‑ends that consume those schemas, handling GROQ queries, caching, and on‑demand revalidation.
• Write and run migration pipelines from legacy CMS platforms (e.g., Umbraco, WordPress, Drupal) into Sanity, including HTML‑to‑Portable Text conversion.
• Maintain redirect maps for large‑scale migrations and implement UI components from Figma designs with full responsiveness and accessibility.
• Leverage AI coding agents to scaffold components, generate schemas, and automate repetitive tasks.
• Participate in code reviews, sprint ceremonies, and client‑facing technical discussions as needed.

Required profile

• Proven production experience with Sanity schema design and Studio configuration.
• Strong expertise in Next.js (App Router, server components) and modern React patterns.
• Solid TypeScript skills and familiarity with GROQ queries.
• Hands‑on experience migrating content from legacy CMSs at volume.
• Ability to translate Figma designs into production‑ready code without extensive specifications.
• Clear written communication for asynchronous coordination.
