• Contractor, Supplier & Site Interface: review integrator, EPC and BOP designs and track comments to closure, handle RFIs and non-conformities quickly during construction, and support FAT/SAT, commissioning, performance testing and handover to O&M.
• Procurement, Schedule & Permitting Support: support tenders (technical scope, specifications, bid comparison), feed engineering status and risks into the project schedule, and prepare technical documentation for permitting and fire authorities.

Job Requirements

• Education: degree in Electrical or Energy Engineering (Mechanical or Civil with strong electrical exposure accepted).

• Languages: fluent Italian and professional English.
• Desirable: BESS fire safety and fire authority interface; hybrid PV and storage projects; commissioning and performance testing on operating plants; document control on large EPC projects.
