Mechanical Designer
Mechanical Designer (2) Open Positions Hourly rates $60-$75 per hour Contract 6 months 40 hours weekly onsite 100% You must be a US Citizen QUALIFICATIONS: Over 5-10 years of experience as a Mechanical Engineering Designer and CAD Documentation Specialist supporting the development of complex, precision scientific instruments Advanced proficiency in 3D CAD modeling and complex assembly process design for electro-mechanical systems Experience designing precision mounts, mirror and lens support structures, alignment mechanisms, and exposure to vibration-isolated assemblies Intuitive understanding of how structural, and thermal requirements are critical to high-accuracy instrumentation Skilled in creating detailed manufacturing drawings with full GD&T application in accordance with industry standards Experienced in tolerance stack-up analysis, fit/function validation, and design for manufacturability (DFM) Developed and maintained configuration-controlled documentation packages, including BOMs, revision tracking, and engineering change management Supported projects from concept development through fabrication, assembly, integration, and testing Collaborated closely with optical engineers, physicists, machinists, and project managers to ensure performance, cost, and schedule objectives were met Committed to precision, documentation integrity, and delivering robust, production-ready mechanical designs DUTIES: Provides technical expertise in the design and preparation of drawings for mechanical, electro-mechanical, and electrical components and assemblies for unique and/or experimental science instruments that are at, or intended to extend, state of the art. This would include the preparation of original layouts, computations, and engineering documentation for varied design features of mechanical and opto-mechanical assemblies, sub-assemblies and component parts of scientific instruments. Translates concepts provided by engineers and/or project scientists into functional designs resulting in associated layout and detail drawings. Conceptual inputs will be in the form of rough sketches, design studies, verbal descriptions, and computer-generated models. Selects effective methods and procedures, adapts available designs and/or develops new designs according to the requirements of each assignment. Interprets and employs conventional engineering principles, practices, guidelines, and precedents in considering design requirements including contamination, structural integrity, corrosion resistance, ground environments, coefficients of thermal expansion, machinability, weldability, formability, etc. as applicable to the design of scientific equipment and components. Performs calculations, studies, and analyses to support designs such as geometric and dimensional tolerance studies, trigonometric calculations, mass property calculations and potential manufacturing, and assembly techniques. Provides engineering staff with calculation results-in either written or tabular form-such as mass properties data derived from computer generated models and tolerance studies
