Senior Infrastructure Engineer

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). #J-18808-Ljbffr Manufact (YC S25)
