• Experience performing electrical load calculations and equipment sizing.
• Knowledge of electrical protection principles and power distribution.
• Experience selecting electrical equipment based on application requirements.
• Ability to select and validate model inputs, understand machine and system dynamics, identify faulty assumptions, interpret complex study results, and make independent design decisions.
• Ability to interpret electrical schematics and one-line diagrams.
• Excellent problem-solving and communication skills.

Requirements

• Design complete electrical power system architectures for mission-critical applications.
• Develop system-level electrical designs based on customer requirements and application needs.
• Perform electrical load analysis, power calculations, and equipment sizing.
• Select and specify major electrical components including:
• Inverters
• Battery energy storage systems
• Power conversion equipment
• Transformers
• Circuit protection devices
• Switchgear and distribution equipment
• Cabling and interconnects
• Evaluate power flow, efficiency, fault current, thermal loading, and overall system performance.
• Collaborate with Controls Engineering to ensure seamless integration between electrical hardware and control systems.
• Work closely with Mechanical Engineering to optimize packaging, cooling, and manufacturability.
• Support prototype development, testing, validation, and field commissioning.
• Participate in design reviews and provide technical leadership throughout product development.
• Research emerging technologies related to electrical power systems, power electronics, and energy infrastructure.
• Develop technical documentation including electrical one-line diagrams, system layouts, specifications, and design calculations.
• Support customer discussions by providing technical expertise during project planning and solution development.

Preferred Qualifications

• Demonstrated experience designing, analyzing, commissioning, or troubleshooting complex power systems in multiple of the following application areas:
• Data center and mission-critical power infrastructure
• Battery Energy Storage Systems, including grid-forming and grid-following converter applications
• UPS and static power-conversion systems
• Inverter-based resources and high-power converter systems
• Generator-based and hybrid power systems
• Microgrids and islanded power systems
• Generation and distribution systems
• Renewable energy integration
• Marine, industrial, utility, or other critical-power applications
• Preferred candidates will have direct responsibility for several of the following:
• Development and review of system one-lines, equipment specifications, protection philosophies, and control narratives
• Load-flow, short-circuit, arc-flash, protection-coordination, motor-starting, harmonic, grounding, and transient-stability studies
• Integration of generators, BESS, UPS systems, inverters, transformers, switchgear, and large dynamic loads
• Analysis of inverter-dominated systems, weak-grid conditions, constant-power loads, power-quality concerns, and control-system interactions
• Electrical equipment selection, grounding design, relay protection, switching philosophy, and system coordination
• Factory acceptance testing, site acceptance testing, commissioning, troubleshooting, and root-cause analysis
• Technical leadership of multidisciplinary projects and review of work performed by other engineers or consultants
• Development of technically defensible recommendations based on study results, equipment limitations, applicable standards, and operating requirements
• Knowledge and application of relevant codes and standards, including, as applicable:
• NFPA 70, National Electrical Code
• NFPA 70E
• IEEE power-system analysis, protection, grounding, and equipment standards
• UL standards applicable to switchgear, power conversion equipment, energy storage, and control systems
• Applicable utility interconnection requirements
• Applicable marine classification, industrial, or mission-critical standards

Location

• Trussville, AL location preferred.
• Remote is acceptable with 30%-50% travel.
• May include travel for customer visits.
