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.

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

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
