Applied Research Associates, Inc. has an exciting and challenging opportunity for a Nuclear Weapons Effects Modeling & Simulation Engineer/Scientist who will support our growing business in modeling and simulation of physical phenomena within a 3D geometric modeling environment. We apply traditional physical modeling approaches as well as machine learning to solve critical problems. As a member of our diverse, multidisciplinary team, you will be responsible for developing engineering and physics-based methodologies, analytical algorithms, and software tools that strengthen our national security.

Our work focuses on modeling a diverse range of phenomena including air blast, ground shock, and structural response modeling. Our models span a wide range of fidelity, from fast-running physics-based models to high fidelity computational fluid dynamics, molecular dynamics, and finite element approaches. As an engineer on our team, your day-to-day work will consist of developing or integrating a wide variety of models into our modeling and simulation software and performing verification & validation on the models to ensure that they produce realistic results.

As a research and development program, the nature of our work varies from month to month and year to year:
You will be continuously challenged to learn and grow expertise in new areas.

The most successful candidates have a strong technical background in engineering and a desire to continue expanding their knowledge. Expertise (and desire!) in writing robust and performant software is also highly desirable. If this describes you, you will be required to work 3 days a week in the Raleigh, NC office.

• Bachelors of Science in Engineering with 2-4 years of experience.
• A strong interest in and ability to develop modeling and simulation software in C++.
• Expertise in other high level programming languages (e.g. Python, Java, etc.).
• Significant academic or professional experience applying principles of structural dynamics.
• A desire to work in a dynamic team environment.

• The nature of work, interactions with intelligence community and DoD programs require eligibility to apply for and hold a US security clearance (selected applicants will undergo a security investigation and must meet eligibility requirements at the time of employment).

Above all, we value passion, a continuous desire to learn, and teamwork. We are confident that if you possess the right attitude, work ethic, and skill set, that you will succeed in the role. In addition to the experience and skills above, if you have any of the following you will be able to accelerate your effectiveness and impact.

• Masters of Science in Engineering with 0-2 years of relevant work experience.
• Expertise in DoD modeling and simulation technology, structural dynamics, nuclear weapon effects, ground shock environments, geotechnical characterization, and/or probabilistic analysis.
• Familiarity with software design patterns, modern C++, and agile software development practices.
• Ability to communicate effectively through verbal and written mediums with technical and non-technical audiences.
