Applied Research Associates, Inc. (ARA) has an exciting and challenging opportunity for a Junior Modeling and Simulation Engineer/Scientist who will support our growing business in theory-driven modeling and simulation of complex systems. As a member of our diverse, multidisciplinary team, you will support the development of computational models, simulations, and analysis tools that strengthen our national security. The successful candidate will have a degree in computer science, engineering, mathematics, physics, or a related field and a strong interest in modeling, simulation, and/or software development.
The systems modeling, analysis, and research technology group develops modeling and simulation software and other tools to support analysis of military systems, including weapons systems, communications systems, and other systems that support national defense. We develop models and conduct simulations over a broad range of spatial and temporal scales using a variety of approaches to support customer objectives. As a member of the team, you will apply your software development and/or engineering/science skills daily to develop creative solutions to challenging problems.
We are a research team, and the application and nature of our work can vary. You will be continuously challenged to learn and grow expertise in new areas. The most successful candidate will have a strong technical background in science, engineering, applied physics, computer science, or mathematics and a desire to continue expanding their knowledge. Experience (and desire!) in writing robust and performant software is also highly desirable. If this describes you, please apply!
If offered this position, you will be an occasional employee, which is an hourly, non-exempt position. As an occasional employee, you are not benefits eligible and hours worked are dependent on the level of support needed.
