Infrastructure Engineer
Hypervisors, storage, network fabric, the layer above the OS and below the app.
A solid generalist seat that compounds for a decade if you keep moving the work forward. Stale ones, you grow out of in two years.
- You like end-to-end ownership across compute, storage, network and identity
- You enjoy systems thinking more than any single technology
- You're happy being the person who knows where every wire goes
- You'll keep migrating workloads to cloud rather than guarding the on-prem moat
- You want a deep specialism, infra is broad by definition
- You'd resent on-call across multiple systems you didn't pick
- You're allergic to change advisory boards and weekend windows
- You can reason about failure modes that span four layers without panicking
- Your changes go through CAB without anyone querying the rollback plan
- Capacity, lifecycle and cost questions come to you before vendors do
- Junior engineers ask for your help on problems they can't categorise
Infrastructure engineer in the wrong org means babysitting a decade-old VMware estate while the rest of the world ships cloud. The salary plateaus and the skills date. The same title in a forward-moving org means owning landing zones, network fabric, identity, observability, and a real seat in design. Same job title, two different careers. Diligence the estate before you accept.
