GTI is a contract manufacturing partner supporting customers in renewable energy, power generation, infrastructure, and industrial systems.We fabricate custom designed, purpose‑built enclosures and skids for our customers and perform mechanical and electrical integration in‑house, delivering a true turn‑key product to our customers. Our scope spans Engineering, prototype builds, through full production, requiring teams that can move fast, adapt, and execute with precision.GTI Values: Safey I Quality I Customer Obsession I Speed I AgilityPosition OverviewGTI Fabrication is seeking a Senior Mechanical Engineer with strong HVAC and thermal systems expertise to lead cooling system design and thermal integration across modular data centers, power systems, and industrial enclosure platforms. This role focuses on HVAC system architecture, equipment selection, airflow management, heat rejection, and integration of packaged cooling systems into highly constrained modular environments.This is not a traditional commercial building HVAC role focused solely on office buildings or facility infrastructure. GTI is specifically seeking engineers who understand how to design HVAC and cooling systems for enclosed equipment, modular systems, industrial infrastructure, and mission‑critical applications where space constraints, manufacturability, vibration, acoustics, serviceability, and thermal performance must all be considered simultaneously.The ideal candidate has experience supporting modular data centers, telecom shelters, BESS systems, generator enclosures, industrial skids, electrical equipment rooms, or other enclosed industrial infrastructure requiring engineered thermal management solutions.Key ResponsibilitiesHVAC System Design & Cooling IntegrationDesign and integrate HVAC and cooling systems for modular data centers, BESS enclosures, power systems, and industrial equipment
