Founding Software Engineer (Product / MCP)

About us

Manufact is Vercel for MCP.
We are building the MCP cloud platform to get any product ready for Claude Connectors marketplace, ChatGPT App Store and any AI agent that supports MCP.
Manufact Cloud usage is more than doubling every month.

We're the team behind mcp-use SDK (next.js for MCP), the open-source framework for building MCP Apps with 10k Github stars and 1'0M+ downloads across python and typescript.

We raised $6.3M seed in 4 days before YC demo day. Our lead investor is PeakXV (best dev-tools VC out there), and we have the best angels, including the founders of Supabase.

Our focus: capture a significant share of global AI tool calls that flow through Manufact.
