About the Role - Project Engineer
As a Project Engineer, you’ll be responsible for the technical and engineering aspects of Peak’s projects. You’ll design site layouts, engage with EPCs, and ensure projects are technically sound, cost-effective, and optimized for execution.

-
Serve as the customer-facing, technical arm of sales and execution, acting as the bridge between Peak’s engineering teams and external stakeholders translating complex technical concepts into clear, actionable insights for customers.
-
Create and optimize site layouts, electrical designs, and conceptual engineering packages for utility-scale storage projects.
-
Manage technical due diligence, including geotechnical, environmental, and interconnection studies.
-
Partner with EPC contractors to evaluate construction methods, cost estimates, and schedules.
-
Support Project Managers in technical aspects of permitting and community engagement.
-
Review and incorporate interconnection requirements, codes, and standards into design.
