Why This Opportunity Stands Out

This role offers the chance to support large-scale, mission-critical data center and hyperscale infrastructure projects across multiple US markets. You’ll be a dedicated estimator, not a dual-hat PM, working closely with experienced delivery and engineering teams. The position provides long-term stability, exposure to complex Division 27 scopes, and the opportunity to influence high-value bids for some of the most demanding infrastructure environments in the industry.

We are seeking an experienced ISP Estimator to join a growing Data Center Division, supporting data center, hyperscale, and carrier hotel projects nationwide. The ideal candidate brings deep expertise in low-voltage infrastructure and structured cabling systems, with proven experience estimating complex internal build-outs for large-scale, mission-critical environments.

This role plays a critical part in developing accurate, competitive, and profitable cost proposals for new construction, retrofit, and expansion projects within data centers and enterprise facilities.
