AI-First Full-Stack Engineer (TypeScript + GCP + ADK + MCP) – Ongoing, Revenue Share Potential

We’re building an AI agent platform that manages Amazon advertising for consumer brands. It’s live and running with real clients. Now we need a builder who can help us move faster. This isn’t a “follow the ticket” role. I’m looking for someone scrappy who uses AI coding tools (Claude Code, Cursor, agents running in parallel) to ship in a day what used to take a week, and who has the taste to make the product look great. Our stack: TypeScript, Google ADK, GCP, Postgres, Redis, Railway What you’ll work on: MCP server infrastructure (Streamable HTTP, stateless, per-user auth scoping) MCP Apps: building interactive UI components that render directly inside AI clients like Claude and ChatGPT Agent architecture with Google ADK: tool design, context management, multi-agent workflows Backend services across GCP and Railway, integrated with Amazon Ads and SP-API Turning a functional web app into a polished, branded product people love to use You’re a fit if you: Write strong TypeScript and have shipped production apps on GCP Have built with Google ADK or a similar agent framework, and understand how agents call tools Have built or deployed MCP servers, and ideally have shipped MCP Apps with interactive UI Are equally comfortable on frontend and backend. You can make a dashboard look beautiful, not just work. Default to AI-assisted development and can point agents at real work Communicate clearly, work independently, and ship without being chased Bonus: Amazon Ads/SP-API experience, OAuth flows, Railway deployments, or e-commerce SaaS experience. Details: 10–20 hrs/week to start, with room to grow Up to $50/hr Revenue share potential for the right person long-term We’ll start with a small paid test project To apply, answer these (generic proposals will be skipped): Link to something you’ve shipped that includes an AI agent, MCP server, or MCP App. What did you build, and what was hard about it? Show me a frontend you’re proud of (live link or screenshots). What’s your AI-assisted dev setup? Which tools do you use, and how do you use agents to parallelize work? Briefly, how would you design an MCP server that serves many client accounts with isolated auth? Start your proposal with the word “PILOT” so I know you read this.
