Profile bio
About Sean Duff
Extensive background with electromechanical radar systems while in the military. This led to a successful career in the building automation industry for new construction and service. After years of experience and completion of several complex clean room, lab, and critical environment automation projects, it gave me a solid foundation for SOO and MEP operation. It was a seamless transition into the IFM hard services (Critical Facilities Engineering) field and my career grew from there. I found a passion in supporting customers through repair and maintenance for simple to extremely complex systems in support of semi-conductor environments. Through experience and performance I was promoted through the ranks into the Senior Critical Facilities Engineering Manager (SCFEM) position that I hold today. I lead a team of 4 managers and 32 engineers in the successful maintenance and repairs for ~1.7Msqft of clean room and lab environments.
Listed skills include Microsoft Excel, Microsoft Word, Project Management, Electronics, and 21 others.
