Guillermo Lopez

- Comercial Aircraft Engines / Externals Hardware - • Identify and execute productivity projects related to comercial engines and parts redesigns. • Collaborate with suppliers at their site, to find cost & producibility opportunities from GE drawings. • Partner with design, manufacturing, and supply chain to optimize drawings and processes. • Externals hardware includes PMC Composites, Forging, Castings, Machining, Sheet Metal and related specs.

- Seats Systems / Customer Team / Mercedes-Benz - • Led the product design development of two complete seat structures for the Mercedes-Benz EQS SUV through the full product development plan. • Performed supplier feasibility studies on Geometric Dimensioning and Tolerancing (GD&T), including tolerance stack-ups and evaluation of new geometries for manufacturability. • Collaborated with Quality and Metrology teams to validate dimensional strategies, inspection methods, and compliance with OEM standards. • Checked and released other design engineers’ drawings, providing feedback on design rules, GD&T application, and tolerance schemes to improve quality and consistency. • Acted as a direct technical contact for the customer on detailed design topics, clarifying requirements and addressing engineering concerns in coordination with the project engineer.

- BOEING 737-MAX, LEAP-1B Engines, Composites Fan Blade production - • Led two Continuous Improvement projects, planning and executing trials, hands-on workshops, and structured trainings to drive process improvements. • Applied basic project management tools and leadership skills to align stakeholders, maintain sponsor engagement, and sustain team commitment throughout the projects. • Designed and delivered training sessions for personnel in Mexico, USA and France, adapting content and delivery to different audiences and sites. • Certified AS9100 internal auditor to support and perform internal audits and external requalification audits.

- Composites Sportive and Military Aircraft prototype - • Resin Transfer Molding trials and documentation to define the fuselage manufacturing process. • Designed and quoted simple fixtures to lift the RTM tooling of the fuselage during the RTM trials. • Tool hand finishing by sanding the surface of the tool prior to the RTM trials. • Defined the location of the resin injection and vacuum gates by running simulations in Moldflow.

- Glass fiber blades for a wind turbine prototype - • Hand elaboration of 24, 13-foot, glass fiber blades using the wet layup method. • Performed vacuum bagging and superficial finishing processes for each elaborated blade. • Defined the minimum thickness for the aluminum inner root cores, advised from a professor.
