ARA is seeking a nuclear engineer to provide technical analysis on projects involving nuclear weapons effects, as well as radiation transport, shielding and detection. Much of the work is focused on gamma and neutron radiation, but our work can also include charged particle radiation, as well as optical and electromagnetic signals. The candidate should have a background in nuclear engineering, radiation transport theory and radiation transport Monte Carlo codes. The candidate should alsohave an understanding of source and types of radiation, radiation transport, radiation interactions with matter, radiation detection and modeling and simulation of radiation transport. What you will do as a nuclear engineer: The candidate will perform radiation transport calculations to determine the total dose acquired at some distance from the source and be able to judge the effect of that radiation deposition. Much of the work will focus on gamma and neutron radiation but the candidate will also model the transport and deposition of alpha and beta radiation, as well as optical and other electromagnetic signals. The candidate will conduct technical analysis to include running radiation transport codes and performing data analysis on the results. The candidate will contribute to written and/or oral reports on the project. The candidate will work with a team of engineers and scientists to provide answers to technical questions. Applicants selected will be subject to a government security investigation and must meet eligibility requirements for access to classified information Required Skills: Candidate must have a strong math, nuclear engineering or physics background. Candidate must be able to work on a team. Candidate must be a US citizen capable of receiving a security clearance. Required Experience BS and 0-2 years of experience. Degree must be in nuclear engineering, physics or closely related discipline. Working knowledge of the radiation transport code MCNP. Desired Qualifications MS degree in nuclear engineering, physics or closely related discipline. Current DOD or DOE security clearance. Familiarity with unstructured mesh in Monte Carlo codes. Familiarity with modeling radiation detector response. Familiarity with the radiation transport code GEANT. Familiarity with computer programming languages such as FORTRAN, C++, Python or Java. Equal Opportunity Employer/Protected Veterans/Individuals with Disabilities The contractor will not discharge or in any other manner discriminate against employees or applicants because they have inquired about, discussed, or disclosed their own pay or the pay of another employee or applicant. However, employees who have access to the compensation information of other employees or applicants as a part of their essential job functions cannot disclose the pay of other employees or applicants to individuals who do not otherwise have access to compensation information, unless the disclosure is (a) in response to a formal complaint or charge, (b) in furtherance of an investigation, proceeding, hearing, or action, including an investigation conducted by the employer, or (c) consistent with the contractors legal duty to furnish information. 41 CFR 60-1.35(c)
