We're looking for a Freelance Senior Full-Stack AI Engineer (Vercel v0 / LLM Systems)

- 100% remote
- 6 months
- Full time

The challenge

Turning a generative model into a system you can trust in production. The team is building the technical harness around Vercel's v0 Platform API: the rulesets, quality gates, sandboxes and fallbacks that make AI-generated storefronts actually shippable, plus the Git and deployment automation that gets them live without a human in the loop.

What you will do

- Integrate and work extensively with the Vercel v0 Platform API and SDK
- Build production-grade LLM workflows: streaming, tool and agent loops, structured outputs
- Develop full-stack functionality with ReactJS, TypeScript, Next.js, Node.js, REST and GraphQL APIs, PostgreSQL
- Build the harness around the models: custom rulesets, execution logic, quality gates, design-system constraints
- Implement error handling, fallback mechanisms and execution sandboxes for generated code
- Automate Git workflows via the GitHub API: programmatic branches, commits, pull requests




- Automate provisioning and deployment through Vercel and/or Netlify APIs, including custom domains and deployment webhooks

What we need

- 6+ years of engineering experience, senior level
- Strong production experience with LLM-based applications: streaming architectures, tool and agent loops, structured output
- ReactJS, TypeScript, Next.js, Node.js, REST and GraphQL, PostgreSQL
- Hands-on with the GitHub API for programmatic branch, commit and PR workflows
- Experience automating deployments with Vercel and/or Netlify APIs
- Fluent / business English
- Available to start October 1st at the latest
- Able to invoice as a freelancer or through your own company (B2B / Ltd)
- Hands-on production experience with the Vercel v0 Platform API and v0 SDK
- Experience designing quality gates or design-system enforcement for AI-generated interfaces
- Experience with execution sandboxes for untrusted or generated code
