Scope the platform mandate before you hire.
Define the production boundary behind a platform title before the search starts to drift.
Platform engineering can describe infrastructure, reliability, internal developer experience, data systems, or a mixture of all four. A title this broad needs a narrow first mandate.
Locate the production boundary
Ask where the system hands responsibility to this person. It might be deployment reliability, compute orchestration, internal tooling, observability, or interfaces used by product teams. The boundary should be visible in the first outcomes.
Name the customer
- Product engineers who need a safer path to production
- Machine learning teams that need dependable training or inference systems
- Operators who need clearer reliability and cost signals
- External developers who depend on an API or SDK
Each customer implies different product judgment, technical depth, and communication patterns. Combining them without priority produces a search that drifts.
Interview the operating tradeoffs
Use scenarios that expose reliability, usability, speed, and cost decisions. Avoid testing a generic catalogue of infrastructure knowledge disconnected from the environment the person will inherit.
Write the first six months
A strong brief can describe what should be more reliable, easier, or more observable after six months without pretending the path is already known.
Platform is a relationship between systems and their users, not a catch-all title.
