Manufacturing Engineer (2nd Shift - 3:30pm - Midnight)

Position Overview

GTI Fabrication is seeking a highly experienced and technically proficient Senior Manufacturing Engineer to lead the design, control, and continuous improvement of manufacturing processes in a modular fabrication environment. In this individual contributor role, you will develop scalable, efficient production methods for custom enclosures, containerized systems, and structural steel weldments. You will work cross-functionally with Engineering, Operations, Quality, and Supply Chain to ensure manufacturability, cost-effectiveness, and regulatory compliance throughout the product lifecycle.

Key Responsibilities

• Design, implement, and optimize manufacturing processes for modular fabricated systems, containerized enclosures, and steel structures.
• Develop formal manufacturing documentation including process flow diagrams, work instructions, BOMs, routings, CNC programming, and assembly/inspection plans.
• Utilize CAD tools (SolidWorks and AutoCAD) to design fixtures, tooling, and work-holding solutions to support scalable production.
• Translate engineering design requirements into robust and efficient production processes.
• Lead new product introduction (NPI) efforts from prototype through full-rate production.
• Apply Lean Manufacturing principles to reduce waste, improve flow, and optimize floor layouts.
• Integrate automated and digital manufacturing technologies where applicable.
• Collaborate with cross-functional teams to evaluate manufacturability and ensure alignment between engineering intent and production capability.
• Utilize ERP systems (NetSuite preferred) to manage process documentation and support real-time operations visibility.
• Maintain compliance with ISO 9001 standards and support internal and external audits.
• Drive root cause analysis and corrective action using tools like FMEA, SPC, and 8D.
• Mentor technicians and junior engineers in best practices for manufacturing engineering.

Required Qualifications

• Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering, or a related field.
• 8–15 years of experience in manufacturing engineering, preferably in modular fabrication, defense, energy, or industrial equipment sectors.
• Proficiency in SolidWorks and AutoCAD for 3D modeling, 2D drafting, and tolerance analysis.
• Strong working knowledge of Lean Manufacturing, Six Sigma, or similar methodologies.
• Experience with ERP/MRP systems (experience with NetSuite is a plus).
• Proven success in process development, design for manufacturability, and scaling production operations.
• Hands-on experience with containerization, modular product platforms, and structural weldments.
• Solid understanding of ISO 9001 quality systems and compliance standards.
• Exceptional analytical, problem-solving, and project management skills.
• Excellent communication and interpersonal abilities.

Preferred Qualifications

• Experience in containerized HVAC, power distribution, or control system enclosures.
• Familiarity with CNC machining, sheet metal fabrication, and industrial coatings.
• Certification in Lean Six Sigma, PMP, or other related process improvement disciplines.
• Experience with CFD/FEA simulation tools.

Working Conditions

• This is a full-time onsite position based in Buffalo, NY, requiring work in both office and fabrication floor environments.
• Occasional travel to customer sites or GTI facilities may be required.
• Must be able to occasionally lift up to 25 lbs and walk fabrication areas.
• GTI Fabrication is an equal opportunity employer committed to building a diverse and inclusive workplace.
