Principal Electrical Engineer - Power Plant Integration Lead

Job Overview

Responsibilities

• Take full engineering ownership of Mainspring's next-generation modular power integration skids, actively translating high-level system architectures into fully commercialized, production-ready assets by driving the design from initial concept through validation and final manufacturing release
• Define and own the skid-level power topology for utility-scale and data center sites, ensuring seamless electrical and physical integration between Linear Generators, central inverters, step-up transformers, switchgear, and energy storage systems (BESS)
• Own detailed skid engineering decisions: hardware selection, spatial layout, thermal management, environmental protection (NEMA/IP rating, seismic/wind loading as applicable), manufacturability, and field serviceability
• Partner actively with internal electrical engineering, mechanical engineering, project delivery, operations, software controls, and supply chain teams to extract, synthesize, and freeze comprehensive system requirements
• Direct and manage third-party design firms and external manufacturers, serving as the primary technical point of contact to ensure engineering and manufacturing outputs align with technical specifications and quality standards
• Drive the scalability and production readiness of larger skid configurations alongside manufacturing suppliers, ensuring the architectural design leverages standardized hardware, reduces site-level installation labor, and is optimized for high-volume replication
• Own the skid's cost target and drive design-to-cost trade-offs across hardware selection, supplier strategy, and configuration options
• Develop a site design configuration tool that specifies the optimal inverter and skid configuration based upon customer site requirements

Qualifications

• Bachelor's or advanced degree in Electrical Engineering or a related field
• 24+ years of direct experience productizing complex, multi-disciplinary industrial systems
• Deep technical knowledge of power conversion systems, including medium-voltage (MV) step-up transformers (12.47kV–35kV), central inverters, switchgear, vacuum circuit breakers, protective relays, and high-current busbar/cabling systems
• Demonstrated experience driving the engineering lifecycle of modular hardware systems, including a strong grasp of design-to-cost principles, supplier capacity scaling, field reliability, and configuration control
• Strong cross-functional leadership skills with a track record of translating diverse technical requirements from electrical, mechanical, and operations teams into a cohesive, manufacturing-ready system design
• Demonstrated success directing 3rd-party design, engineering, or Contract Manufacturing (CM) partners from initial concept through to sustained volume production
• Strong working knowledge of grid interconnection standards, utility protection schemes, and safety/compliance frameworks (e.g., IEEE 1547, UL 1741 SB/SA, NFPA 70/NEC, NFPA 855)

Bonus Qualification(s)

• Skilled in SCADA integration, industrial networking, and designing or certifying control systems to UL 508/508A standards
