As a Senior Estimator, you’ll play a key role in delivering utility-scale solar, wind, and battery energy storage projects across the U.S. This role goes far beyond quantity takeoffs—you will lead large conceptual EPC bids, shape pricing strategy, evaluate risk, and coordinate directly with Directors, VPs, and Executives to build winning proposals.
Location: You will work onsite from our fast-growing Phoenix, AZ office, supporting projects nationwide while maintaining local stability and minimal job-site travel. This position gives you the opportunity to mentor junior estimators, collaborate across Engineering, Procurement, Scheduling, and Construction, and influence the pursuit of billion-dollar renewable infrastructure projects that support long-term U.S. energy needs.
