Founding Software Engineer (Product / MCP)

About us

Manufact builds dev-tools and cloud infrastructure for MCP and software used by AI agents.

Our platform helps teams build, deploy, test, and distribute MCP servers and apps across ChatGPT, Claude, Muse, Grok Bot, and other AI agents.

• Why now: MCP is becoming the most important product surface for every company.
• Growth: Tool calls on our infra +38% WoW since June (there's a live counter on our website).
• Open source: We created mcp-use SDK (Next.js for MCP) for building MCP Apps with 10k Github stars and 10M+ downloads.
• Backed by the best: Y Combinator (S25) and raised a $6.3M seed round led by Peak XV, with investors including the founders of Supabase.
• Our goal: A big portion of global MCP tool calls will run on Manufact.

We believe every software company will need an agent interface, just as it needs a website today.
