José Valdir Calixto

I am a Senior Mechanical Design Engineer with over fourteen years designing industrial equipment, piping systems, and large-scale projects using SolidWorks and AutoCAD. I specialize in bulk material handling, conveyor systems, and wastewater treatment equipment, combining detailed CAD work with practical application engineering.

At Martin Engineering I develop heavy-duty transfer chutes, conveyor belt cleaning applications, and detailed assemblies and BOMs, while improving team productivity through internal CAD tutorials and project-tracking tools. Previously, I led mechanical design for Brazil's largest wastewater treatment system and supported implementation of Nereda technology, increasing delivery throughput through SolidWorks best practices.

I bring a fast learning curve, high productivity, and experience with ERP item registration (Protheus TOTVS), process optimization, and interim engineering management. I seek roles where I can apply advanced CAD skills to complex mechanical systems and drive continuous improvement in design and delivery.
