This is a remote position with occasional travel, anticipated at 10%–25%, for project site visits during construction administration and site surveys at existing facilities. Approved business travel expenses are reimbursed under company policy. Candidates interested in office-based or hybrid arrangements may discuss available options.

The engineer leads mechanical design from feasibility through construction administration; develops cooling system concepts and resiliency strategies; oversees analyses, equipment selection, and technical reviews; coordinates with other disciplines and vendors; and supports commissioning and staff development. The position offers an annual salary range of $120,000–$170,000.
