3D CAD & Prototype Design Engineer

Leitat Technological Center • Freelance

Feb 2023 - Dec 2025 • 2 yrs 10 mos

Worked on 3D CAD development and prototype-oriented engineering projects involving product components, mechanical assemblies and manufacturing-ready designs. Translated product concepts, technical requirements and existing references into accurate digital models suitable for prototyping, validation and further manufacturing development. Created detailed mechanical parts and assemblies while paying close attention to dimensions, interfaces, tolerances, component relationships and manufacturability. Developed design iterations based on prototype evaluation, engineering feedback and functional requirements. Supported the preparation of CAD files for different production and prototyping methods, including additive manufacturing and conventional manufacturing processes. Generated and modified STL, STEP and other CAD formats depending on project requirements. Worked on redesign and reverse-engineering tasks involving existing physical components or reference models, recreating their geometry and improving the design where required. Maintained structured CAD assemblies and documentation to make designs easier to review, manufacture and modify.

Product Development & Prototyping Designer

Eurecat • Freelance

Jan 2022 - Aug 2024 • 2 yrs 7 mos

Contributed to product-development and prototyping projects, transforming early concepts and engineering requirements into detailed 3D CAD models and functional prototype designs. Worked through different stages of development, from initial concept interpretation and component modeling to design refinement and prototype preparation. Developed individual mechanical components and complete assemblies while considering dimensions, tolerances, clearances, fastening methods, material selection and manufacturing requirements. Modified designs based on prototype testing and engineering feedback to improve functionality, assembly and overall product performance. Prepared CAD models and supporting technical drawings for prototyping and manufacturing activities. Worked with different CAD workflows to convert sketches, reference images, existing parts and engineering information into structured 3D models. Also supported reverse-engineering and redesign tasks by recreating existing components, improving problematic geometry and adapting products for new manufacturing or functional requirements.

Mechanical & Product Design Specialist

BCN3D Technologies • Freelance

Feb 2021 - Nov 2023 • 2 yrs 9 mos

Worked on mechanical and product-design projects focused on additive manufacturing, functional components and prototype development. Responsibilities included developing detailed 3D CAD models from concepts, sketches, references and existing components, while considering dimensional accuracy, assembly requirements, material constraints and 3D-printing limitations. Created and modified mechanical parts, housings, brackets, functional assemblies and prototype components using professional CAD workflows. Prepared models for different additive-manufacturing processes and refined geometry to improve printability, strength, fit and usability. Also supported design iterations by modifying existing CAD models based on testing feedback, identifying potential mechanical issues and preparing updated prototype versions. Produced manufacturing and technical documentation where required and maintained organized CAD files for continued product development.
