 * Active TS/SCI Clearance is preferred

Special Requirements:

 * This position requires the ability to obtain and maintain a Sensitive Compartmented Information (SCI) clearance from the Department of As such, this position is a Workplace Substance Abuse (WSAP) testing designated position. WSAP positions require passing a pre-placement drug test and participation in an ongoing random drug testing program. In addition, due the SCI, you may also be subject to random polygraph testing.
 * This position is a full-time staff position.

## Description

The Advanced Engineering Technologies (AET) Group is seeking a Computational Fluid Dynamics Analyst specializing in the use and development of computational simulation software for complex aerodynamic systems in the support of the nonproliferation mission space. This position will involve the creation and use of custom developed and off-the-shelf computational approaches in a research and development atmosphere., * You will, in collaboration with principal investigators and project management at ORNL, participate in the development of simulation software to model complex system flows in processes relevant to the nuclear nonproliferation mission space.

 * You will be expected to be a heavy end user of the tools generated, participate in model validation activities, identify workflow improvements, and communicate issues to the development team for tool
 * Analysis of ad hoc problem sets relevant to the nuclear nonproliferation mission space is expected.
 * Performing well as part of a larger project team and being capable of developing simulation software in a collaborative development environment.
 * In addition to these responsibilities, you will be a contributor to R&D projects and will be expected to report on and brief results throughout the lifecycle of the various projects assigned to them.
 * In this position effectively interacting with various ORNL staff as well as internal and external sponsors is required.
 * If selected, you will be expected to work in a team environment with co-workers and management as well as independently; to fully document work performed in the forms of technical reports, papers and presentations; and to participate in the development of research proposals.
 * You will interface with principal investigators, management, engineers, fabricators, modelers, and test campaign personnel., AET resides within the Nuclear Nonproliferation Division (NND) at Oak Ridge National Laboratory (ORNL). The NND is a division operating within the National Security Sciences Directorate. NND staff contributes world class research, technology development, risk assessment, and systems analysis related to nonproliferation and counterproliferation. The division activities play a vital role in implementation of national policy issues that strive to ensure global nuclear security. One of the major focus areas of the AET group is the development of advanced approaches to operation, characterization, and analysis of nuclear fuel cycle processes. The group specializes in the application of engineering principles supporting the characterization of processes and related materials. The AET group collaborates and works with staff from other groups within NND and ORNL to assure the full expertise of fuel cycle processes are applied to meet sponsor needs.
