About The Position

As Paragon Space Development celebrates 32+ years of providing award-winning life support and thermal control solutions for extreme environments, we've recognized that it is our employees that keep our business thriving. By any measure, Paragon is an exciting and rewarding place to work. Our goal is to hire the best and allow you to do the work that you enjoy! Do you want to make a difference immediately? Are you ready to apply your aerospace design engineering skills to develop cutting edge life support and thermal control products for extreme environments on Earth and in space? Are you ready to play a critical role literally doing what has not been done before? Can you excel in that team environment and carry your share of the load while also relying on others to do their part? If this sounds like you, we want you to join Paragon Space Development Corporation now. Description of Duties: Independently and/or collaboratively formulate and perform static structural, fatigue and fracture analysis of aerospace components, assemblies, and systems Support generation of static, dynamic, and fatigue test plans and procedures, special test equipment, and sensor placement. Perform data analysis and model correlation. Work with design engineers to help drive weight optimized, structural sufficient parts Generate formal documentation such as technical memorandums, analysis reports, design and development books, or product manuals Ability to work effectively in a fast-paced interdisciplinary environment with changing needs and requirements
