Staff Mechanical Engineer

Position Overview

GTI is seeking a Staff Mechanical Engineer to provide senior technical leadership across complex modular power and industrial systems. This role will serve as a technical authority for mechanical system design, structural and thermal analysis, equipment integration, and troubleshooting while supporting projects from concept through manufacturing, testing, and production.

The ideal candidate brings extensive hands-on experience designing industrial equipment, generator enclosures, fabricated steel structures, equipment skids, and modular systems, along with strong engineering calculation capabilities and the ability to mentor engineers and solve complex cross-functional technical problems.

Key Responsibilities

Mechanical System Design & Technical Leadership

• Lead mechanical system architecture and design for complex modular power and industrial systems.
• Develop and review mechanical designs for generator enclosures, structural frames, equipment skids, sheet metal assemblies, weldments, and integrated mechanical systems.
• Design and integrate generators, cooling systems, fuel systems, piping, exhaust systems, and associated mechanical equipment.
• Perform and review engineering calculations involving structural loads, stress, deflection, vibration, fatigue, thermal performance, and fluid systems.
• Perform and validate finite element analysis (FEA) on structural frames, welded assemblies, lifting structures, and equipment supports.
• Establish technical direction and provide guidance on complex or first-of-kind mechanical designs.
• Lead design reviews and resolve high-level technical issues across multiple projects.

Structural, Thermal & Mechanical Integration

• Evaluate structural designs for operational, lifting, transportation, wind, seismic, and other applicable loading conditions.
• Develop mechanical layouts supporting equipment integration, service access, thermal management, and manufacturability.
• Support cooling system design, airflow analysis, heat rejection, and thermal management for generator systems, BESS, and modular infrastructure.
• Collaborate with Electrical and Structural Engineering teams on equipment interfaces, system requirements, and integration challenges.
• Support mechanical testing, design validation, troubleshooting, and root-cause investigations.
• Provide technical support to manufacturing, integration, field service, and customers.

Manufacturing & Product Development

• Ensure mechanical designs are manufacturable, serviceable, safe, and aligned with customer requirements.
• Work closely with Electrical Engineering, Structural Engineering, Manufacturing, Quality, Supply Chain, Program Management, and Operations.
• Support prototype builds, production launches, design changes, and continuous product improvement.
• Develop and maintain production-ready mechanical drawings, engineering calculations, BOMs, specifications, and design documentation.
• Provide technical guidance on fabrication, welding, machining, assembly, and mechanical integration.
• Resolve complex manufacturing and product performance issues through engineering analysis and practical design solutions.

Mentorship & Engineering Excellence

• Mentor Senior and Mechanical Engineers and provide technical review of engineering work.
• Help establish mechanical engineering standards, calculation methods, design guidelines, documentation practices, and validation methodologies.
• Serve as a technical resource for complex customer, certification, manufacturing, and field issues.
• Lead technical design reviews and provide guidance on engineering assumptions, analytical methods, and design decisions.
• Identify opportunities to improve design quality, efficiency, reliability, and repeatability across programs.

Qualifications

Required Qualifications

• Bachelor's degree in Mechanical Engineering or a related engineering discipline.
• 12+ years of relevant mechanical engineering experience, preferably in industrial equipment, power generation, modular systems, or custom manufacturing.
• Demonstrated experience leading complex mechanical designs from concept through manufacturing and production, including collaboration with fabrication and assembly teams.
• Strong experience designing fabricated steel structures, industrial enclosures, equipment skids, weldments, or integrated mechanical systems.
• Advanced proficiency in SolidWorks, including large assemblies, sheet metal, weldments, and manufacturing documentation.
• Strong experience performing mechanical engineering calculations, structural analysis, and FEA.
• Demonstrated ability to solve complex technical problems, lead design reviews, and mentor engineers.

Preferred Qualifications

• Experience with generator systems, BESS, modular data centers, or mission-critical power infrastructure.
• Experience with thermal management, airflow, cooling systems, or fluid system design.
• Familiarity with ANSYS, SolidWorks Simulation, or similar engineering analysis tools.
• Knowledge of applicable ASME, AISC, UL, or related engineering standards.
• Professional Engineer (PE) license or FE/EIT certification.
