Monitor and defend the operational technology that keeps water levels where they should be.

Rijnvliet manages pumping stations, weirs and treatment plants. Their control systems are on a network that must never be reachable from the wrong place, and monitoring that is a full time job. You work in a small security operations team: alert triage in the SIEM, tuning detection rules for an OT environment, and running exercises with the operators. The BIO framework is your baseline. Temp-to-hire, moving to a permanent water authority contract after a year. Arnhem, thirty six hour week, and work that has a very visible consequence if it goes wrong.
