What is a Platform Engineer?
A platform engineer builds the internal infrastructure, developer tooling, and shared services that other engineers depend on to build product. Distinct from DevOps (which focuses on deployment pipelines) and SRE (which focuses on reliability), platform engineering focuses on the developer experience — making it faster and easier for product engineers to build, test, and deploy code without managing infrastructure themselves.
At what stage should you hire a Platform Engineer?
Series B and beyond, when the engineering team has grown to 20–30+ engineers and the developer experience starts to become a meaningful productivity constraint. The signal: engineers are spending a significant portion of their time waiting for CI, debugging environment issues, or working around missing internal tooling. Platform engineers create leverage across the entire engineering organization.
