Hardware Deployment & Maintenance Engineer

Granite is building sovereign AI infrastructure for Europe compute energy and a new generation of AI technology running in modular liquid-cooled containers that it specifies builds and operates itself. The first containers went live in 2026. More are in build. Now Granite needs the person who keeps the hardware running.

About the role

This is a founding role. You will be the first person at Granite whose full-time job is the deployed fleet which means you are not joining an existing maintenance function you are building one. Within six months you will have written the procedures established the spares model and set the standard that every container after the first one runs on.

• Own spares and asset management end to end inventory tracking and lead times across every site in the fleet.
