**Description** Applied Research Associates, Inc. (ARA) in Dayton, OH is seeking an independently motivated and detail-oriented engineer to create CAD models and prepare high quality surface and volumetric meshes/grids for a variety of computational physics software packages. The unique and strict requirements of each computational package require different modeling and meshing approaches for each problem. As such, a successful candidate must be willing to work closely with a team of computational scientists and engineers to understand the requirements of each package, and preferably learn to run some analyses. **Specific Duties Include:** + Accept CAD models in multiple formats from a variety of outside sources + Prepare incoming models for analysis by doing some or all of the following: + Defeaturing + Surface healing + Boolean operations + Reconstruction of missing or poor-quality components + Generate high quality meshes using multiple meshing programs based on unique requirements of different computational methods + Write scripts to speed the process of generating meshes of many different densities for a single geometry + Understand how CAD and mesh quality and attributes affect the ability of individual computational physics packages to compute correct results + Occasionally reverse engineer CAD components by laser scanning or approximating components based on photographs or CT scans **Required Qualifications:** + Bachelor’s **(or equivalent)** with 4+ years’ experience + 4 years’ experience with CAD + Functional experience at least one of the following CAD/meshing software packages: Solidworks, Capstone (CREATE-Genesis), CUBIT (Sandia National Labs), Rhinoceros 3D, CATIA, Hypermesh, AutoCAD, Patran, NASTRAN, NX (Siemens), Creo (PTC) + Ability to obtain a security clearance **Highly Desired Qualifications:** + Bachelor’s degree in engineering, physics, computer science, or related discipline + Active security clearance + Knowledge of or eagerness to learn computational analysis, scripting, and other related skills **COMPANY INFORMATION:** Applied Research Associates, Inc. is an employee-owned international research and engineering company recognized for providing technically superior solutions to complex and challenging problems in the physical sciences.
