Jeff Erno works at the front edge of how engineering is evolving.

His work spans Computer Aided Design (CAD), simulation, and Product Lifecycle Management (PLM), with a focus on early-phase design, configuration at scale, and the data structures required for AI to move beyond reading engineering data… to actually learning from it.

Jeff holds multiple patents across CAD methods, turbomachinery, and model-based automation, reflecting a career grounded in building—not just describing—engineering systems.

He is known for bringing clarity to complex topics—and for challenging the industry to move beyond legacy approaches that limit innovation.

At Dassault Systèmes, he helps companies rethink how products are defined—not as disconnected files and BOMs, but as unified, model-based systems that capture intent, relationships, and decisions.
