Mechanical Engineer with 5+ years of experience specializing in product development, mechanical design, and manufacturing-ready CAD solutions. I help companies, startups, and inventors transform early concepts into fully engineered products that can be prototyped, manufactured, and scaled. My expertise combines strong theoretical engineering knowledge with practical manufacturing experience, allowing me to design parts and systems that are not only functional but also optimized for real-world production. Technically, I specialize in SolidWorks-based product development, including full assembly modeling, parametric part design, and detailed manufacturing drawings using Geometric Dimensioning and Tolerancing (GD&T). My workflow focuses heavily on Design for Manufacturing (DFM) and Design for Assembly (DFA) principles to ensure that parts are cost-effective to produce and easy to assemble. I also perform Finite Element Analysis (FEA) for structural validation and use simulation tools to evaluate stress, load paths, and potential failure modes early in the design process. My experience spans multiple manufacturing processes including sheet metal fabrication, CNC machining, welding, composite manufacturing, and assembly line production. Because of this, I approach every project with a strong understanding of real manufacturing constraints, supplier capabilities, and production economics. In addition to mechanical design, I also develop automation systems and engineering workflows that improve operational efficiency for businesses. This includes creating custom automation solutions that integrate engineering processes with digital tools to reduce manual work and streamline product development cycles.

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’m 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 let me know if I can be of assistance. Sincerely, David Mitchell
