Summary / Role Purpose

Join the Ansys Customer Excellence team to partner with our customers to engineer what's ahead, solve their real-world 3D modeling problems, deploy Ansys software in their design workflows, and grow Ansys’ business.  A 3D Modeling Support Engineer becomes an expert in integrating CAD and 3D models into Digital Mission Engineering workflows, solving some of the most challenging problems in the aerospace and defense industry.

Based out of the Ansys Government Initiative (AGI) office in Exton, PA, the 3D Modeling Support Engineer is responsible for assisting our customers and our products team with the creation and modification of 3D models for use in the STK application. 


STK is used for land, sea air and space applications across a broad scope of industries (aerospace, defense, autonomous vehicle design and operation, communications analysis, etc.).  The 3D models used in STK are much more than visual representations, they are used for detailed mission analysis workflows including sensor obscuration, solar panel power collection analysis, antenna/sensor placement and more.

A successful 3D Modelling Support Engineer will be able to create technically accurate, detailed models with an understanding the level of fidelity required by each customer use case and an ability to adapt the model features to meet those needs.  They will demonstrate a willingness to learn new things; as 3D modeling technology and tools change, Ansys will stay at the leading edge of industry capabilities.  STK also employs many unique capabilities within our 3D models, including articulations, solar power computations, pointing vectors and more that will require creativity and problem solving to implement.  It is also very important to have a strong dedication to our customer’s mission, as it drives everything we do.  Finally, as a customer facing role, it requires strong communication skills, patience and an ability to teach complex concepts.
