Electrical Engineer, High Voltage

IPX Power is a clean energy company that develops, owns, and operates large energy resources, focusing on solar PV and battery storage. The Electrical Engineer will lead the technical execution of high-voltage and medium-voltage systems for utility-scale projects, overseeing engineering decisions from development through operations.

Responsibilities:

• 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

Requirements:

• 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, consultants, vendors, and cross-functional teams through project lifecycle execution
• Ability to independently diagnose and resolve plant and substation issues using relay data, SCADA, inverter logs, plant historian and equipment diagnostics, and drive fixes through to implementation
• Direct working knowledge of major power system equipment, including operation, failure modes, and troubleshooting
• Strong working knowledge of NERC PRC & MOD standards and regional requirements (CAISO, ERCOT) related to plant operation and compliance
• Deep understanding of HV/MV equipment, protection and control schemes, metering, substation SCADA, and design trade-offs (technical vs cost vs schedule)
• Solid foundation in power system studies and modeling
• Proficiency with steady-state modeling tools (ETAP, SKM, DIgSILENT, or similar)
• Advanced Excel skills for technical and financial analysis
• Familiarity with NEC, NESC, IEEE standards
• Strong balance of high voltage substation & collection system design, power system studies, field-level equipment understanding, and real-world troubleshooting experience, including testing
• PE license preferred
• Preferred working knowledge of PSSE, PowerWorld, and PSCAD but not mandatory
• Masters or PhD is a plus
