Software Engineer: Modeling & Simulation

TitleSoftware Engineer: Modeling & Simulation

Location: Charlottesville, VA; Seattle, WA; Washington, DC

ARiA applies broad interdisciplinary expertise in acoustics, machine learning, modeling & simulation, and signal processing toward innovative science and engineering research and development for a diverse set of government and corporate clients. Partnering with government, industry, and academia, ARiA solves critical challenges.

To enable effective and efficient transition of applied research to advanced development of products and systems, ARiA is structured to bring together top-quality research scientists with development and software engineers in an environment in which research and development mutually benefit from joint leveraging of in-house expertise.

ARiA is a small business where you can make a big difference. Our employees, including those at entry-level, are working together with the CIO of the Air Force to use artificial intelligence and machine learning  to change the way the government acquires technology and working with top Navy leaders to use video games and simulation to change the way sailors are trained to use sonar.
