About The Position

GTI is seeking a Staff Mechanical Engineer to provide senior technical leadership across complex modular power and industrial systems. The role serves as a technical authority for mechanical system design, structural and thermal analysis, equipment integration, and troubleshooting, supporting projects from concept through manufacturing, testing, and production. The position calls for extensive hands-on experience with 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 address cross-functional technical problems.

GTI is a contract manufacturing partner serving customers in renewable energy, power generation, infrastructure, and industrial systems. It fabricates custom enclosures and skids and performs in-house mechanical and electrical integration, supporting work from engineering and prototype builds through full production. The environment requires teams that can move quickly, adapt, and execute with precision.

• 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.
• Ability to solve complex technical problems, lead design reviews, and mentor engineers.

Nice To Haves

• 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.

Responsibilities

• Lead mechanical system architecture and design for complex modular power and industrial systems.
• Develop and review 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 related mechanical equipment.
• Perform and review calculations involving structural loads, stress, deflection, vibration, fatigue, thermal performance, and fluid systems.
• Perform and validate FEA on structural frames, welded assemblies, lifting structures, and equipment supports.
• Establish technical direction for complex or first-of-kind mechanical designs; lead design reviews and resolve high-level technical issues across projects.
• Evaluate structural designs for operational, lifting, transportation, wind, seismic, and other applicable loading conditions.
• Develop mechanical layouts for 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 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.
• Ensure designs are manufacturable, serviceable, safe, and aligned with customer requirements.
• Work 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, 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.
• Mentor Senior and Mechanical Engineers and technically review 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.
• Provide guidance on engineering assumptions, analytical methods, and design decisions during technical design reviews.
• Identify opportunities to improve design quality, efficiency, reliability, and repeatability across programs.
