Job description

Description

Position Summary

Foresight On-Site (FOS) is transforming semiconductor construction, and we're looking for an exceptional executive to help shape what's next. As one of the industry's fastest-growing C4 licensed semiconductor construction companies, we're building a senior leadership team to support our next phase of growth; from more than 100 employees today to over 300 in the coming years. Backed by Foresight Technologies, a global leader in high-purity manufacturing with more than 1,000 employees across Arizona and Malaysia, you'll have the opportunity to lead an organization uniquely positioned to deliver innovative construction solutions for the world's leading semiconductor manufacturers. Foresight Technologies is a leader in manufacturing for Fab-scale Hi Purity Water systems, Valve Boxes, Chemical Distribution systems, Chemical Containment, and large amounts of prefabricated piping spools to speed up Fab Construction while reducing cost.

The ideal candidate combines deep technical expertise in C4 licensed high-purity piping systems, chemical distribution systems, and semiconductor construction with strong business acumen and intellectual curiosity. They thrive on solving complex construction challenges, collaborating with customers and cross-functional project teams, and continually improving how estimates are developed. More than simply assigning costs, they understand that exceptional estimating requires developing innovative, constructable solutions that reduce risk, optimize project execution, and position both the customer and Foresight for long-term success.
