Work Environment

This is an on-site contract position in Boise, Idaho supporting an active semiconductor construction project. The role requires field presence, participation in system walkdowns and testing activities, and compliance with all site safety and PPE requirements.

FusionIRX is a specialty construction management firm focused exclusively on the most technically demanding facilities on earth — semiconductor fabs, data centers, and EV battery plants. We exist to give owners the expertise and discipline they need to succeed at this scale.

Advanced manufacturing facilities are among the most complex construction projects ever attempted. They involve thousands of interdependent work packages, ultra-high technical specifications, compressed delivery timelines, and regulatory environments that leave no room for error. FusionIRX was built to navigate this complexity on behalf of the people who own these facilities.

Our team brings decades of direct experience managing semiconductor fab construction, data center delivery, and EV battery plant development. We are not generalists who occasionally work on complex projects. This is all we do.
