About The Position

GTI Energy designs and manufactures complex modular systems supporting modular data center infrastructure, energy storage, and power generation platforms. Operating in a high-mix, engineered-to-order environment, GTI integrates structural, mechanical, and electrical systems into fully assembled modular units. Our production model requires precision mechanical assembly, system integration, and disciplined execution to deliver mission-critical infrastructure. GTI Energy is seeking a Millwright to support mechanical assembly and system integration within modular data center builds at our Goodyear, AZ facility. This role is responsible for installing, aligning, and assembling mechanical equipment and systems including cooling infrastructure, pumps, piping systems, and structural components within prefabricated modules. The Millwright will work from mechanical drawings, isometric drawings, and Bill of Materials (BOM) to assemble and integrate complex systems in a production-driven environment. This role requires strong mechanical aptitude, precision alignment skills, and experience working with industrial equipment and modular or skid-based systems.
