Why Manufact?
At Manufact, we’re building the infrastructure layer for the next generation of software: AI agents.
Our platform helps developers build, test, and deploy MCP servers and AI-powered applications that integrate directly with tools like ChatGPT and Claude. We’re creating the foundation for a world where software is consumed not just by humans, but by autonomous agents.
In a short time, our open-source SDKs have reached millions of downloads and are used by thousands of developers and companies worldwide.
You’ll be joining a very small, fast-moving team with roots in Zurich and San Francisco. This is an opportunity to work directly with the founders and contribute to a product used at scale by cutting-edge AI teams.
Joining Manufact at this stage means high ownership, fast learning, and real impact from day one.
Your Role
At Manufact, you won’t just “do tasks”. You’ll help build core infrastructure for AI agents.
This is a hands-on engineering internship where you will primarily work on backend systems, while also contributing to DevOps and parts of the frontend as needed.
You’ll ship real features used by developers building AI products, and see your work in production quickly.
