Penetration Tester - Infrastructure/OT (Consultancy | Mostly Remote | Not for Beginners) Right. Let’s skip the fluff. One of our consultancy clients needs an experienced Infrastructure Pen Tester. Not someone who wants to be a Pen Tester. Not someone halfway through their OSCP. Someone who's been there, and got some of the battle scars already. They work with … sort of environments where “turning it off and on again” could cost millions. So yeah, it’s not your average test. The Job (in plain English): You’ll be testing infrastructure - manually. No Web App fluff, no clicking “scan” in a tool and writing up the results. You’ll be dealing with proper kit and real-world impact. A … lot of autonomy, and the expectation that you can figure things out without someone holding your hand.
