Utility-Scale BESS Project Engineer (Grid Integration)

Job DescriptionJob DescriptionShape the future of grid-scale energy storage

Picture a day where you translate ambitious renewable goals into detailed engineering designs, then walk a site to confirm that every conduit, foundation, and interconnection aligns with the plan. As a Project Engineer on our Utility Scale Energy Storage team, you guide battery energy storage systems from early concept through commissioning, collaborating with project managers, suppliers, construction partners, and cross-functional stakeholders to maximize performance and reliability.

What your day may look like

• Lead the design phase for large-scale BESS, engineering major components and coordinating multi-discipline resources.
• Scrutinize drawings and studies to catch inconsistencies early, drive corrective actions, and raise the bar on design quality and efficiency.
• Develop clear, comprehensive technical scopes of work for contracts and vendor engagements.
• Work hand-in-hand with project managers from inception to completion, influencing engineering decisions and keeping milestones on track.
• Track technical issues and progress; surface risks early and propose mitigation plans.
• Partner with suppliers to specify and integrate major equipment, ensuring seamless systems and controls integration.
• Translate equipment specifications into actionable requirements, ensure unambiguous communication, and recommend practical solutions.
• Navigate permitting needs, propose strategies to address legal and code-related challenges, and recommend site design improvements.
• Support logistics and construction, performing technical due diligence and data analysis to optimize system performance.
• Consult across internal and external teams to propose storage solutions that elevate BESS performance.
• Take on additional responsibilities as needed to move projects forward.
