    Hello! I am a Mechanical Design Engineer offering eight (8) years of product-development experience within manufacturing settings across multiple industries including aerospace, consumer products, medical, industrial, and energy. During my time in the aerospace industry I’ve honed my skills and proven my ability to create cost-effective, cutting-edge designs that meet project and product specifications. Also I’m an expert user of CAD programs and skilled producer of mechanical engineering documentation and drawings. I have 14 years of experience with 2D and 3D CAD design. I am proficient in structural analysis, mechanics, process engineering, and thermodynamics. My aptitude in CAD extends to systems and product design including components and assemblies, detail drawings, geometric dimensioning and tolerancing (GD&T), assembly drawings, engineering BOM’s, and stress analysis. From 2008-2013 I worked at Blue Origin in Kent WA as a design engineer for the propulsion and structural/mechanical groups. Through my engineering knowledge I developed design solutions for aerospace vehicles, systems, and components in the conceptual design phase, as well as, having sole responsibility for specific vehicle subsystems and hardware throughout the design process. Over the course of this position I worked on 3 different space vehicles. I was the responsible engineer for tests of integrated systems on multiple occasions. This entailed orchestrating tests and leading groups of people. In the last year I have worked as a freelance mechanical design engineer during which time my cross industry exposure has been significant particularly relating to injection molded plastic parts, consumer product design, 3D printing, and design automation (API). Please take your time to look through my profile and/or resume and let me know if I can be of assistance. Sincerely, David Mitchell
