## What they're looking for

- The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would
- You've secured substations, SCADA, or controls systems in production: Ignition or comparable platforms, PLCs, relays, and the industrial protocols beneath them
- You've threat modeled OT environments and turned the results into segmentation and controls that operators could live with
- You think in the Purdue Model and know when to break it, because virtualized PLCs and software-defined OT don't always fit the reference architecture
- You've worked hands-on with common OT security tooling (Claroty, Nozomi, Dragos, or similar) and know what each class of tool can and can't see
- You know BMS, EPMS, and cooling systems well enough to hold your own with the engineers who run them
