The role spans concept development, utility interconnection, detailed design, procurement, construction support, commissioning, and energization. The ideal candidate has direct experience integrating natural-gas reciprocating-engine (RECIP) generator plants.\nYour Mission:\nEstablish the electrical design basis, scope boundaries, interface matrix, deliverable register, design schedule, and technical risk register; identify and close scope gaps across owners, EPC contractors, utilities, consultants, and equipment suppliers.\nReview electrical design packages including: single-line and three-line diagrams, wiring diagrams, cable schedules, equipment layouts, grounding and lightning-protection designs.\nCreate or technically evaluate specifications for all major equipment including: transformers, HV/MV switchgear, disconnect switches, power cables, CTs/VTs, metering and protection relays and UPS systems.\nCoordinate electrical interfaces with natural-gas engine-generator OEMs, including alternator ratings, neutral grounding, excitation/AVR, governor and synchronizing controls, generator protection, starting systems, plant auxiliaries, black-start or islanding requirements, and CHP interfaces where applicable.\nReview load-flow, short-circuit, protection-coordination, grounding, arc-flash, cable-ampacity; ensure study assumptions remain aligned with the issued-for-construction design.\nManage utility interconnection requirements, including point-of-interconnection design, revenue metering, communications and relay settings.\nReview EPC and vendor drawings, calculations, equipment data sheets, test plans, FAT/SAT reports, deviations, and technical submittals; provide clear dispositions and maintain design configuration control.\nSupport procurement through equipment specifications, technical bid evaluations, supplier selection and vendor-document review.\nProvide construction engineering support, respond to RFIs and field changes, participate in site walkdowns, and verify that installations conform to the design, applicable codes, and approved quality plans.\nPlan and support substation energization, generator synchronization, commissioning, and turnover, including test procedures, protection and control testing, punch-list closure, and coordination with utilities, commissioning agents, and plant operations.\nYour Background:\nBachelor’s degree in engineering (electrical or power system engineering) or equivalent experience.\n7+ years of experience leading project design, preferably in the building of large generator power stations and substations.\nDirect experience in HV/MV substation design.\nDirect experience with natural-gas reciprocating-engine power plants, CHP facilities, or distributed generation is strongly preferred.\nWorking knowledge of applicable IEEE, ANSI, NFPA 70/NEC, NESC, NETA, OSHA, and utility standards.\nPE certification or equivalent, preferred.\nFamiliarity in permitting processes with local authorities.\nProficient in Microsoft Office tools (Excel, Word, PowerPoint).\nWillingness to travel domestically and internationally, up to 30%.\nComfortable thriving in fast-paced, rapid growth environments.\nA passion for sustainability, our mission, and our vision is a bonus!\nMust successfully pass a pre-employment background check.\nEnergy Vault participates in E-Verify.\nBenefits of Powering the Future with Energy Vault:\nAnnual bonus plan.\nRestricted Stock Units (RSUs).\n401K employer matching.\nComprehensive medical, dental, and vision plans for employees and family.\nFlexible Spending Account.\nCompany-paid Life insurance, Short- and Long-term disability insurance.\n8-weeks for Paternity leave.\nGenerous holiday allowance.\nFlexible time off plus sick leave.\nReimbursement for home office equipment, phone, and internet expenses.","description_format":"text","description_chars":4078,"description_truncated":false,"requirements":{"experience_years_min":7,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["401k
