The Senior Manufacturing Engineer will work cross-functionally with Engineering, Operations, Quality, and Supply Chain to ensure manufacturability, cost-effectiveness, and regulatory compliance across 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.
• Use 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; 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 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 (NetSuite a plus).
• Demonstrated success in process development, design for manufacturability, and production scaling.
• Hands-on experience with containerization, modular product platforms, and structural weldments.
• Knowledge of ISO9001 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 related process improvement disciplines.
• Experience with CFD/FEA simulation tools.

Working Conditions:

• This is a full-time onsite position based in Phoenix, AZ.
• Work takes place in both office and fabrication floor environments.
• May require occasional travel to customer sites or GTI facilities.
• Must be able to occasionally lift up to 25 lbs and walk fabrication areas.
