Security Engineer, OT

Fluidstack, San Francisco, CA +4

What you need

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 https://jobs.ashbyhq.com/fluidstack/05c2e69c-42f9-4fcb-9cf0-a467aaf98f1c.

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.
You've moved security forward in engineering teams that don't report to you, through consultation and design review rather than mandate.
