Manufacturing / Assembly / Mechanical Integration

Employment Type

Full-Time

Company Overview

GTI Energy operates in a contract manufacturing and industrial manufacturing environment focused on building and integrating complex modular systems. Our production model includes fabrication, assembly, electrical integration, and mechanical system installation within a high-mix, engineered-to-order environment. We support modular infrastructure including cooling systems, power systems, and system-level builds where precision, quality, and execution are critical.

Position Overview

GTI Energy is seeking a Mechanical Installer – Chilled Water Systems to support installation and integration of industrial piping systems within modular builds. This role is responsible for assembling pre-fabricated pipe spools, installing chilled water piping systems, and connecting mechanical equipment including pumps, valves, and related components.

This position is not a welding role. The Mechanical Installer focuses on pipe fit-up, alignment, flange connections, and system integration using isometric drawings and Bill of Materials (BOM). Success in this role requires strong understanding of mechanical systems, piping layout, and installation within tight, production-driven environments.

Key Responsibilities

Pipe Installation & Mechanical Assembly

• Install pre-fabricated pipe spools as a Mechanical Installer across chilled water and mechanical piping systems

• Hang pipe using supports, brackets, and mounting systems within modular structures

• Align and bolt flanges to ensure proper fit-up and system integrity

• Install valves, pumps, fittings, and associated mechanical components

• Ensure all piping installations meet drawing specifications and system requirements

System Integration & Equipment Connection

• Connect piping systems to pumps, heat exchangers, and cooling equipment

• Support system integration within modular builds, ensuring alignment with mechanical and electrical components

• Verify proper installation of piping systems for functionality and accessibility

• Assist with system testing and commissioning activities as required

Drawing Interpretation & Layout

• Read and interpret isometric drawings (ISO drawings), P&IDs, and mechanical layouts

• Calculate offsets, angles, and takeoffs to ensure accurate installation

• Follow Bill of Materials (BOM) to ensure correct component usage and system configuration

• Identify and resolve fit-up issues during installation

Quality, Safety & Execution

• Ensure installations meet quality standards and ISO9001 requirements

• Maintain proper alignment, torque, and connection integrity across all piping systems

• Follow OSHA safety standards and internal safety protocols

• Support First Pass Yield (FPY) by minimizing rework and installation errors

Lean Manufacturing & Continuous Improvement

• Support Lean Manufacturing, 5S, and Continuous Improvement initiatives within the production environment

• Identify installation inefficiencies and support improvements in flow, cycle time, and takt time

• Participate in Root Cause Analysis using 5 Whys and Fishbone methodologies for installation issues

Cross-Functional Coordination

• Partner with Engineering to resolve layout, fitment, and integration challenges

• Collaborate with Production and Supply Chain to ensure material availability and installation readiness

• Work with Quality teams to address defects and improve installation processes

Required Qualifications

• 2–5 years of experience as a Pipefitter, Mechanical Installer, or Industrial Pipe Installer

• Experience installing piping systems in industrial, modular, or mechanical environments

• Strong ability to read isometric drawings, P&IDs, and mechanical layouts

• Experience with pipe installation, flange alignment, and mechanical system assembly

• Familiarity with chilled water systems, cooling systems, or mechanical piping

• Ability to calculate offsets, angles, and perform basic layout work

Preferred Qualifications

• Experience in modular construction, skid-based manufacturing, or system integration environments

• Background in industrial HVAC, chilled water systems, or process piping

• Experience installing pumps, valves, and mechanical equipment

• Exposure to Lean Manufacturing, Continuous Improvement, or structured problem solving

• OSHA 10/30 or similar safety certifications
