Are you ready to take the next step in your construction career and help shape the future of clean energy? We’re looking for a self‑driven, resourceful, and disciplined Assistant Project Manager to support the successful delivery of utility‑scale solar projects across the U.S. This is a high‑impact, growth‑oriented role designed to develop future project leaders. You’ll be part of a team that partners with top energy clients nationwide to build a more sustainable future—one solar project at a time.

Working directly onsite, you’ll collaborate with field teams, subcontractors, and senior leadership to ensure projects are executed safely, on time, and within budget. You’ll play a critical role in managing day‑to‑day operations, tracking progress, and solving problems in real time—while learning the full project lifecycle from pre‑construction through close‑out.

You will travel across the U.S., helping our team build renewable projects. This is a traveling position (up to 100%) where you will be onsite at a project location. You may be placed on a project site in any state throughout the U.S. You’ll spend an average of 8‑16 months on each project. We offer a designated daily per diem in addition to base pay to support living expenses, plus a vehicle allowance and routine travel home from the jobsite.
