Shai T.
Mechanical Engineer - Design, Research and Development
Hi, I’m Shai, a mechanical design engineer with over 12 years of experience helping teams turn ideas into functional, manufacturable products. My background spans the full product development cycle, from early R&D and concept design to prototyping, testing, and production handoff. I’ve worked across medical devices and consumer products, leading designs that balance creativity, precision, and manufacturability. I enjoy solving complex mechanical challenges and finding elegant, practical solutions that make real-world impact. Core skills include: 3D CAD modeling & detailed drawings (SolidWorks expert) Design for Manufacturing (DFM) & supplier-ready documentation Prototyping & mechanical testing (with in-house 3D printing capability) Packaging and assembly design (including validation and testing) Electro-mechanical and optical integration Rapid concept development and iteration I’m quick to communicate, easy to collaborate with, and bring a hands-on approach to every project, whether it’s refining an existing design or building something entirely new.
