Overview
We are seeking a hands-on Lead Electrical Engineer to own the electrical design, integration, and commissioning of complex power systems for industrial energy projects. This role will be responsible for HV/MV/LV power architecture, utility interconnection, protection and coordination, grounding, control cabinet design, and field commissioning support.
The ideal candidate brings strong experience in power distribution, grid-connected systems, utility coordination, NEC/FC1/UL/CE compliance, arc-flash analysis, and practical execution from concept through commissioning. Experience with hydrogen, electrolysis, fuel cells, data centers, temporary microgrids, modular substations, or industrial power systems is highly desirable.
Key Responsibilities
• Lead electrical architecture for industrial power systems, including HV/MV/LV distribution, transformers, switchgear, auxiliary power, UPS systems, and grounding.
• Own utility interconnection requirements, including interface with utilities, EPCs, vendors, and internal engineering teams.
• Develop and review single-line diagrams, three-line diagrams, grounding plans, panel layouts, electrical room layouts, BOMs, cable schedules, and electrical design packages.
• Perform or lead protection and coordination studies, relay settings, arc-flash analysis, and arc-energy-reduction strategies.
• Ensure designs comply with applicable NEC, IEEE, NESC, UL 508A, NFPA, and site-specific electrical standards.
• Support DC power system design, including rectifiers, DC distribution, insulation monitoring, grounding/earthing strategy, fault limitation, and overvoltage protection.
• Lead UL 508A control cabinet design, review, and manufacturing support.
• Translate high-level system requirements into buildable electrical packages suitable for procurement, fabrication, installation, and commissioning.
• Support RFQs, bid leveling, vendor selection, technical reviews, FAT, SAT, energization, LOTO planning, and startup procedures.
• Coordinate with mechanical, controls, process, software, and field service teams to ensure integrated system performance.
• Provide field support during installation, commissioning, troubleshooting, and customer acceptance.
• Develop internal electrical standards, design guides, templates, and best practices to improve repeatability and reduce design cycle time.
• Mentor junior engineers and support technical development across the electrical engineering team.
Required Qualifications
• Bachelor's degree in Electrical Engineering or related field.
• 10+ years of electrical engineering experience in industrial power systems, utility interconnection, power distribution, controls, or commissioning.
• Strong working knowledge of NEC, IEEE standards, UL 508A, grounding, bonding, electrical clearances, and electrical safety practices.
• Experience with MV/LV power distribution, transformers, switchgear, relays, protection coordination, and arc-flash studies.
• Experience developing electrical design packages, including SLDs, layouts, schematics, BOMs, and commissioning documentation.
• Ability to interface effectively with utilities, EPCs, vendors, customers, and internal engineering teams.
• Hands-on commissioning, troubleshooting, or field execution experience.
• Strong communication skills and ability to drive technical alignment across cross-functional teams.
Preferred Qualifications
• Engineer-in-Training, PE, or ability/desire to pursue PE licensure.
• Experience with hydrogen, electrolyzers, fuel cells, renewable energy, data centers, microgrids, or modular power systems.
• Experience with DC power systems, including rectifiers, 1,000 VDC+ distribution, insulation monitoring, and DC fault protection.
• Familiarity with ETAP, AutoCAD Electrical, EPLAN, SolidWorks Electrical, ElectricalOM, or similar tools.
• Experience with utility-scale or industrial power systems up to MV/HV levels.
• Experience with generator plants, BESS, black-start systems, load shedding, or temporary power applications.
• Experience developing internal standards or converting international designs to U.S. NEC/IEEE requirements.
Key Competencies
• Power system architecture
• Utility interconnection
• Protection and coordination
• Arc-flash and electrical safety
• Grounding and earthing
• UL 508A control panels
• DC power systems
• Field commissioning
• Vendor and EPC management
• Practical, buildable design execution
Success Measures
• Electrical packages are code-compliant, buildable, and released on schedule.
• Utility approvals and interconnection requirements are secured with minimal rework.
• Protection, grounding, and safety designs are technically sound and field-ready.
• Commissioning and energization activities are completed safely and efficiently.
• EPC/vendor change orders are reduced through clearer requirements and better upfront design quality.
• Internal standards and templates improve engineering repeatability across future projects.
