IPX Power, a clean energy company, develops, owns, and operates some of the world’s largest energy resources, delivering affordable, reliable power to utilities and other customers. We’re in a rapid growth phase with 4.3 GW of solar PV and 8.8 GWh of battery storage in construction or operation, with more projects under various stages of development.   IPX is a profitable, well capitalized, independent power producer that has delivered billions of dollars of industrial-scale clean energy infrastructure. The company was recently formed as a spin-out of Intersect, as a result of their recent acquisition by Google. IPX is supported by long-standing existing investors TPG Rise Climate, Climate Adaptive Infrastructure, and Greenbelt Capital Partners.   IPX is rooted in a culture of collaboration, creativity, and operational excellence. We’re building and operating billions of dollars in assets and seeking people eager to develop, build, and operate one of the world’s largest renewables and storage portfolios About This Role The Electrical Engineer will lead the end-to-end technical execution of high-voltage (HV) and medium-voltage (MV) systems across utility-scale solar and battery energy storage projects. This role owns critical engineering decisions spanning utility interconnection, substation and transmission design optimization, and MV collection system performance—from early-stage development through financing, construction, commissioning, and into operations. The role requires a strong balance of  high voltage substation & collection system design, power system studies, field-level equipment understanding, and real-world troubleshooting experience, including testing . You will be expected to diagnose and resolve issues across protection systems, transformers, breakers, cables, and substation control systems. Beyond project delivery, you will lead root-cause analysis of system events and drive targeted upgrade and retrofit initiatives to improve fleet reliability, availability, and compliance. What You’ll Do Lead design and technical review of HV substations (115kV–500kV), transmission interconnections, and MV collection systems (34.5kV–480V). Direct EPCs, Engineers of Record, and consultants to optimize design, reduce execution risk, and maintain schedule and cost targets. Own utility interconnection scope, including review of applications, steady-state and dynamic models, and technical negotiations with ISOs/utilities (e.g., CAISO, ERCOT). Lead field-informed troubleshooting of system events, including relay operations, misoperations, nuisance trips, and equipment failures. Perform root-cause analysis using relay event reports, oscillography, Substation SCADA data, and equipment diagnostics (e.g., DGA, infrared, insulation testing). Define and implement upgrade and retrofit projects, including protection setting changes, control system tuning, equipment replacement, and design corrections to improve reliability and performance. Provide NERC and regional regulatory (CAISO/ERCOT) compliance support, ensuring operational readiness and adherence to PRC and related standards. Support Operations with ongoing technical issue resolution and performance optimization across the fleet. Develop and maintain engineering standards, technical specifications, EPC exhibits, and testing protocols. Witness and evaluate FAT/SAT, commissioning, and energization activities. Support EPC RFPs and supply agreements by defining enforceable technical requirements. Contribute to Independent Engineer (IE) diligence and project financing. Drive cross-functional coordination to resolve permitting, regulatory, and technical constraints. What You’ll Bring Minimum 8+ years of experience leading technical scope for HV substations (345kV–500kV) and MV collection systems (up to 34.5kV) within an IPP, EPC, or engineering firm. Proven experience managing EPCs,
