Jobs in Nantes, France

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.

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.
