Full-Stack Developer (AI & Web Platform)

A headless architecture: Sanity.io as the content backend, Next.js on the frontend, deployed via Vercel. The migration is underway, and we are looking for a developer who can carry it forward, own the platform long-term, and bring genuine expertise in AI-assisted and agentic engineering workflows.

This is not a traditional web maintenance role. The right candidate writes clean, production-quality code and also knows how to build solutions where AI agents are first-class participants in the workflow. You will work alongside Claude as a co-author and co-builder, not just a search tool.

Website Platform Ownership

• Maintain and extend the DemandScience.com headless stack (Sanity + Next.js + Vercel)
• Complete the ongoing automated migration pipeline moving ~455 pages from WordPress to Sanity
• Own schema design, component architecture, and Vercel ISR configuration
• Manage deployments, environment variables, webhook integrations, and staging environments
• Maintain third-party integrations including Pardot, GTM, GA4, Hotjar, Drift, and review widgets

AI-Assisted Development

• Design and build agentic workflows where AI handles structured, repeatable tasks such as content extraction, transformation, QA comparison, and draft generation
• Use the Sanity MCP server and Claude API in production workflows, not just for one-off prompts
• Build Vision QA pipelines (Playwright + Claude screenshot comparison) and other automated validation steps
• Contribute to the AI co-authoring layer that enables Marketing to publish content with AI assistance and Dev oversight

Marketing Self-Sufficiency

• Work with Marketing to define content ownership, review workflows, and editing guardrails in Sanity Studio
• Reduce Dev dependency for routine content updates by building well-structured schema and reusable content patterns
• Document processes so Marketing and non-technical stakeholders can operate independently

Core Requirements

• 5+ years of professional web development experience with a strong JavaScript/TypeScript foundation
• Demonstrated experience building production applications with agentic engineering patterns: multi-step AI pipelines, tool use, structured output, human-in-the-loop checkpoints
• Comfortable integrating LLM APIs (Anthropic, OpenAI, or equivalent) into real production systems, not just demos
• Experience with headless CMS architecture and the separation of content from presentation
• Familiarity with REST APIs, webhook-driven architectures, and JSON-based content pipelines
• Strong communication skills; able to explain technical tradeoffs clearly to non-technical stakeholders
• Must be willing to work on Graveyard Shift

Preferred Experience

• Sanity.io: Schema design, GROQ queries, Sanity Studio customization, MCP integration, and Content Lake concepts
• Vercel: Deployment configuration, ISR, edge functions, environment management, and preview environments
• Next.js: App Router, server components, dynamic routing, and API routes
• Playwright: Automated browser testing and screenshot comparison pipelines
• WordPress: Familiarity with the REST API for migration and extraction work (ongoing pipeline context)
• Claude API: Tool use, vision tasks, structured outputs, and prompt engineering for production workflows

What Good Looks Like

The strongest candidates will have done something like this before

• Built a pipeline where an AI agent reads structured input, performs a multi-step task, and hands off to a human for review before anything goes live
• Designed a Sanity schema from scratch and built the Next.js components to consume it
• Written an automated migration or ETL script that transformed messy legacy content into clean structured data
• Debugged a production agentic workflow and added robust error handling, retry logic, and observability

You do not need to have done all of these. But the pattern matters: you build systems, not just features, and you think about what happens when something goes wrong.
