3

Showcase your ability to collaborate with IT teams—mention how you've bridged cultural and technical gaps between IT and OT.

4

Quantify achievements: e.g., 'Reduced unplanned downtime by 20% through proactive OT monitoring' or 'Secured 10+ plant networks with zero incidents.'

5

Mention familiarity with industry standards like IEC 62443, NIST, or Purdue Model, as ERMCO prioritizes security and compliance.

✉️ What to Emphasize in Your Cover Letter

["Your vision for integrating IT and OT to support ERMCO's grid modernization and energy transition goals.", "Specific examples of how you've secured and optimized OT infrastructure in a manufacturing environment, ideally in energy or utilities.", 'Your leadership style in managing remote teams and cross-site collaboration, given the multi-facility scope.', "Alignment with ERMCO's values: safety, operational excellence, and continuous improvement, with anecdotes demonstrating these."]
