About GTI Energy
GTI Energy, a division of GTI Fabrication, is a fast-growing industrial manufacturer specializing in battery systems, energy storage enclosures, and modular infrastructure for mission-critical energy and defense markets. Our integrated design and fabrication capabilities allow us to deliver high-quality, engineered solutions from concept to full-scale production.
Position Overview
We are seeking an experienced Cabling & Harness Engineer to design, develop, and support electrical harness and cabling systems for GTI’s advanced battery systems and energy storage devices. This role will be responsible for the end-to-end lifecycle of wiring systems — from concept and design to manufacturing support and quality validation.
The ideal candidate is a hands-on engineer with strong knowledge of industrial electrical systems, wire harness design, and cable routing for high-voltage and low-voltage energy applications.
Key Responsibilities
Design and develop wiring harnesses, cable assemblies, and interconnect systems for modular energy storage and battery systems.
Create detailed schematics, wiring diagrams, pinout charts, and bill of materials using CAD and electrical design software (SolidWorks Electrical, AutoCAD Electrical, or similar).Define conductor sizes, insulation types, shielding, connectors, strain reliefs, and protective coverings suitable for harsh industrial environments.Manufacturing Support & DocumentationGenerate complete manufacturing documentation, including harness assembly drawings, work instructions, and routing layouts.
Collaborate with manufacturing teams to ensure harness designs are optimized for manufacturability, reliability, and cost.Support harness assembly builds on the production floor, resolving issues during first article and pilot runs.Quality & ComplianceEnsure harness designs comply with industry standards (UL 508A, NFPA 70 / 79, IPC / WHMA-A-620) and customer specifications.
Support electrical validation and testing of harness assemblies, including continuity, hipot, and insulation resistance testing.Conduct design reviews, root cause analysis, and corrective actions on harness-related quality issues.Cross-Functional CollaborationWork closely with electrical engineers, mechanical engineers, and supply chain teams to integrate harness designs into overall product architecture.
Coordinate with vendors on component selection, harness tooling, and supply lead times.Continuous ImprovementDrive improvements in harness design practices, documentation standards, and assembly processes.
Evaluate new connector technologies, wire types, and harness manufacturing methods for use in next-generation energy systems.Required Qualifications
