Qualifications - 3–6 years of hands-on commissioning experience on BESS, solar + storage, or utility-scale renewable energy projects. - Direct experience with battery storage systems including BMS, PCS/inverter, and EMS/SCADA commissioning. - Proficiency reading and interpreting electrical schematics, single-line diagrams, and P&IDs. - Working knowledge of protection relay testing, CT/PT verification, and DC/AC high-voltage systems. - Strong technical writing skills; ability to produce clear field reports and commissioning documents. - Valid driver’s license and US passport. - Ability to travel >80% of the time. Preferred Qualifications - Hands-on experience with one or more major BESS OEMs (Tesla Megapack, BYD, CATL, Sungrow, or similar). - Familiarity with SCADA communication protocols: DNP3, Modbus TCP/RTU, etc. - Familiarity with utility interconnection processes (distribution and transmission). - NETA, NICET, or relevant electrical certifications. - OSHA 10 or OSHA 30 certification; NFPA 70E training. - Bachelor’s degree in electrical engineering, Power Systems, or a related technical field (or equivalent field experience). Soft Skills - Technically sharp, highly organized, and comfortable leading a small team in fast-paced construction environments. - Strong communicator across EPC, OEM, and internal stakeholders. - Autonomous and accountable. - Safety- and quality-first mindset.
