Company Overview
GTI designs, engineers, and manufactures complex modular systems supporting energy storage, power , data center infrastructure, defense, and industrial markets. GTI delivers fully integrated, engineered-to-order solutions including Battery Energy Storage Systems (BESS), generator-backed power systems, and modular data centers manufactured in-house.

Position Overview
GTI is seeking a Senior Electrical Engineer to lead electrical system design and development across advanced modular programs, including BESS, GenSet-based power systems, and modular data center infrastructure. This role owns electrical architecture, schematic development, and technical execution for complex power and control systems operating across varying voltage levels and power capacities.

The Senior Electrical Engineer serves as a technical authority, working closely with mechanical engineering, manufacturing, supply chain, and project teams to ensure designs are safe, scalable, manufacturable, and compliant with applicable standards. This role requires strong experience in power distribution, control systems, and electrical documentation within industrial or energy-focused environments.

Key Responsibilities

Electrical System Design & Architecture

• Lead electrical system design for Battery Energy Storage Systems (BESS), generator systems, and modular data center power infrastructure
• Develop electrical architectures supporting varying levels of power , storage, and distribution
• Design AC and DC power systems, including low-voltage and medium-voltage applications as required by project scope
• Define system-level power distribution, protection, grounding, and control strategies

Schematic Development & Documentation

• Create and maintain detailed electrical schematics, wiring diagrams, and single-line diagrams using SolidWorks Electrical or equivalent
• Develop panel layouts, cable schedules, and interconnection diagrams
• Ensure electrical documentation is complete, accurate, and production-ready
• Maintain revision control and support engineering change management

BESS, GenSet & Power Integration

• Design electrical systems integrating battery systems, inverters, transformers, generators, switchgear, and protection devices
• Support parallel operation, load sharing, and backup power configurations
• Design control and monitoring interfaces between power systems and control platforms
• Support integration of power and storage systems into modular enclosures

Modular Data Center Electrical Design

• Support electrical design for modular data center infrastructure including power distribution units (PDUs), UPS systems, generators, and switchgear
• Design redundant and fault-tolerant power architectures (e.g., N+1, 2N)
• Support integration of cooling, monitoring, and control systems from an electrical perspective

Cross-Functional Engineering Support

• Partner with Mechanical Engineering to ensure electrical designs integrate with enclosures, thermal systems, and physical layouts
• Support Manufacturing Engineering with design-for-manufacturability and build strategy input
• Provide technical guidance to production teams during build, test, and integration
• Support troubleshooting and root cause analysis during prototype builds and production

Compliance, Standards & Safety

• Ensure designs comply with applicable electrical codes and standards such as NEC, UL, IEC, and project-specific requirements
• Support UL-listed and customer-certified system designs
• Apply safety best practices in power system design and documentation

Project & Technical Leadership

• Serve as a technical lead on assigned programs
• Support project planning, technical risk identification, and issue resolution
• Mentor junior engineers and designers as needed

Required Qualifications

• Bachelor’s degree in Electrical Engineering or related discipline
• 8+ years of experience in electrical engineering roles within industrial, energy, or infrastructure environments
• Strong experience designing power systems across varying voltage and power levels
• Proven experience developing electrical schematics and documentation
• Experience with power , energy storage, or critical power infrastructure
• Strong understanding of AC/DC power systems, protection, and controls

Qualifications

• Experience with Battery Energy Storage Systems (BESS)
• Experience with generator systems, paralleling switchgear, and backup power architectures
• Experience supporting modular data centers or mission-critical infrastructure
• Proficiency with SolidWorks Electrical
• Experience supporting UL-listed or code-compliant system designs
• Prior experience in modular, containerized, or engineered-to-order manufacturing environments
