The OT Field Services Tech II is an experienced field-based technical professional responsible for independently performing troubleshooting, corrective maintenance, repairs, functional testing, and field implementation activities for Operational Technology (OT) systems supporting RWE’s power-generation assets.

Working within defined processes and approved procedures, the role addresses moderately complex faults involving OT field devices, communication links, basic network-connected equipment, and power supplies. The Tech II interprets OT diagrams, network drawings, wiring schematics, equipment manuals, and device parameters to diagnose issues and implement practical technical solutions.

The role coordinates field activities with Operations, OT support, Engineering, project teams, and vendors, including access arrangements, outage windows, planned maintenance, and small equipment modifications. The Tech II supports commissioning and operational handover by verifying installation, connectivity, configuration, and functional performance; maintains accurate work and asset documentation; contributes feedback on recurring issues and improvement opportunities; and provides informal guidance to junior technicians in safe work practices, troubleshooting, and documentation standards.
