Electrical Engineer, Power Systems

NGEN Mission Critical is a U.S.-based provider of critical power and cooling infrastructure, serving data centers, AI factories, and utility-scale power generation. They are seeking an Electrical Engineer to lead product development and technical ownership for large electrical equipment targeted at data center and mission critical customers in the U.S. market.

Responsibilities:

• Own the full design management lifecycle from early site assessment and basis of design through schematic design, design development, and construction documents
• Lead electrical product definition, detailed design review, and performance requirements for transformers, GIS, UL 891 switchboards, UL 1558 panel boards, and ancillary electrical equipment
• Create and review single-line diagrams (SLDs), wiring schematics, interconnection diagrams, and installation/commissioning documents suitable for mission-critical facilities
• Define electrical ratings, insulation coordination, dielectric/impulse withstand criteria, thermal ratings, tap-changer strategies, and specifications for protective devices and controls
• Perform system studies including short-circuit, load flow, protective device coordination, arc-flash, transient stability (as required), and harmonics analysis using ETAP or equivalent tools
• Specify and validate protection and control schemes (relay selection, settings, CT/PT requirements) and coordination studies for integration with customer T&D systems and onsite generation
• Interface technical outputs with utility transmission/distribution practices and ensure designs accommodate U.S. T&D requirements and interconnection constraints
• Own conformity to NEC, UL product standards (UL 891, UL 1558, UL/IEEE transformer standards as applicable), IEEE, and relevant NERC/utility requirements as they apply to product scope
• Coordinate factory testing, type tests, and witness testing (routine, short-circuit, temperature-rise, DGA for transformers, dielectric tests for GIS) with suppliers and third-party test labs
• Support certification programs and provide technical packages required by certifiers and U.S. authorities
• Work closely with overseas suppliers on design transfer, prototype review, manufacturing process controls, and corrective actions based on FAT outcomes
• Define FAT/SAT acceptance criteria, BOM control, spare parts lists, and test procedures; participate in supplier FATs and customer SATs as required
• Provide technical direction on producibility, quality controls, and value engineering while protecting NGEN product requirements
• Use PLM/ECN tools to manage product configurations, revisions, drawings, and release processes (experience with Teamcenter, Windchill, or equivalent)
• Produce and maintain design dossiers, SCDs/SOPs, test reports, installation guides, and O&M documentation
• Ensure drawings and documentation comply with U.S. practice and are suitable for AHJs, certifiers, and installation teams
• Support site commissioning, energization, and post-installation troubleshooting; lead root-cause investigations for field failures and coordinate supplier remediation and engineering changes
• Provide technical escalation support to sales, service, and operations for complex project issues

Requirements:

• Bachelor's degree in Electrical Engineering (power emphasis) or equivalent; advanced degree is a plus but not required
• Minimum 8+ years' experience in electrical design, power systems engineering, or product development for large electrical equipment (transformers, switchgear, switch boards, or utility T&D equipment)
• Deep, demonstrable knowledge of U.S. transmission and distribution systems and the interface requirements with customer sites
• Proficiency in single-line diagram creation and review; demonstrated ability to produce SLDs suitable for utility and mission-critical site integration
• Hands-on experience with ETAP or an equivalent power-systems simulation suite for load-flow, short-circuit, protection coordination, and arc-flash studies
• Expert-level knowledge of the NEC and practical experience applying NEC to equipment selection, installation, and commissioning
• Familiarity with UL 891 switchboard requirements and UL 1558 panel board standards and practical implications for product design and factory testing
• Experience with PLM and configuration management workflows for product releases, ECNs, and engineering documentation
• Proven track record working directly with offshore suppliers on product development, factory testing, and supplier corrective action implementation
• Strong technical writing skills for producing specifications, test plans, and commissioning documents
• Excellent communication skills; able to represent NGEN to customers, utilities, suppliers, and certifiers
