Manufact, the YC‑S25 startup, is hiring a Senior Infrastructure Engineer to build its MCP cloud platform. The role offers $100K – $180K and 0.10%–0.70% equity, based in San Francisco or remote.

Manufact is the Vercel for MCP, scaling its cloud usage each month. The team released the mcp‑use SDK, an open‑source framework with 10k GitHub stars and over 7M downloads, used by 20% of the US 500, including NASA, SAP, and NVIDIA. The company raised $6.3M seed in 4 days before the YC demo day, with Peak XV as lead investor and angels from Supabase.

The engineer will build the cloud platform that hosts customer MCP servers, set up observability, alerting, and error handling, and ensure scalability for thousands of users. They will also create tooling for customers to deploy Manufact privately on AWS, Azure, or GCP and enforce data isolation.

Requirements include end‑to‑end cloud operations, experience with logs, metrics, traces, and dashboards at scale, and knowledge of Kubernetes, Terraform, and containerized multi‑tenant systems. The interview process involves a founder call, a design exercise on hosting and observability, and a paid trial with the team.
