Senior Electrical Engineer - Battery Energy Storage Systems

Position Overview

GTI is seeking a Senior Electrical Engineer to lead the electrical architecture and schematic development of modular Battery Energy Storage Systems (BESS). This role is responsible for designing electrical distribution systems, protection schemes, control architectures, and equipment interfaces supporting integrated battery energy storage platforms.

The ideal candidate will have strong experience designing industrial power systems involving high-power electrical distribution, protection coordination, and integration of inverters, transformers, switchgear, and monitoring systems within production-driven engineering environments.

Key Responsibilities

Electrical System Architecture & Design
Design electrical architectures for modular BESS platforms including AC and DC power distribution systems
Develop single line diagrams, electrical schematics, wiring diagrams, panel layouts, and cable schedules
Integrate battery systems, battery management systems (BMS), PCS inverters, transformers, switchgear, and auxiliary electrical systems
Define grounding strategies, isolation methods, and electrical protection schemes for high-power energy systems
Support redundant and fault-tolerant electrical designs aligned with system reliability and safety objective
Protection, Controls & Safety Systems
Develop monitoring, alarm, shutdown, and control logic supporting safe battery operation
Evaluate electrical risks including fault current analysis, protection coordination, thermal impacts, and system isolation requirements
Support designs aligned with UL 9540 energy storage certification requirements and applicable electrical safety standards
Coordinate with controls, software, and integration teams supporting SCADA, EMS, and energy monitoring interfaces
Support commissioning activities, Factory Acceptance Testing (FAT), troubleshooting, and field support as require
Cross-Functional Integration
Coordinate electrical system design with mechanical layouts, enclosure constraints, thermal systems, and manufacturing requirements
Collaborate with Mechanical Engineering, Manufacturing, Quality, Supply Chain, and Integration teams throughout product development and production
Support equipment selection, technical evaluations, vendor coordination, and electrical design reviews
Participate in design reviews, prototype builds, and production launch activities
Documentation & Production Support
Develop production-ready electrical documentation supporting manufacturing, assembly, integration, and field service
Maintain strong engineering documentation discipline including revision control, BOM support, drawing packages, and change management
Support root-cause investigations and corrective actions related to electrical integration, commissioning, or production issues
Assist in standardizing electrical architectures and documentation practices across BESS platforms
