Job description: ### About us [Manufact](https://manufact.com) 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](https://github.com/mcp-use/mcp-use) (next.js for MCP), the open-source framework for building MCP Apps with **10k Github stars and 8M+ downloads** across python and typescript. \ Used by 20% of US 500 like NASA, SAP, NVIDIA and more than 5,000 companies. 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.** ## What you'll do * Build the cloud platform that hosts customer MCP servers with millions of tool calls. * Set up monitoring, observability, and dashboards across every MCP server on Manufact Cloud and the full stream of events and logs we ingest, so problems surface before users feel them. * Build alerting and error handling that flags threshold breaches and failures in real time. * Make sure the platform scales as we add thousands of users and capture a growing share of global AI tool calls. * Create the tooling and technical blueprints that let customers deploy Manufact into their own private clouds (AWS, Azure, GCP) on their own terms. * Build the security boundaries that keep each customer's data private and isolated within their own environment. * Own where our code lives and how it ships: code hosting and the release pipeline. * Keep the system fast and reliable as companies add more MCP servers. ## Requirements * You have built and operated cloud systems end-to-end and know them inside out. * Experience standing up the observability stack that keeps a cloud healthy: logs, metrics, traces, dashboards, and alerting at scale. * Kubernetes or Terraform, and containerized multi-tenant systems. * Comfortable being the first person to own infrastructure at a fast-growing startup. * Based in or willing to relocate to San Francisco. ## Nice to have * Hands-on with observability tooling such as ClickHouse, Prometheus, OpenTelemetry, Grafana. * Experience running a platform that others deploy onto (PaaS-flavored).
