Job Description

We have an opening for a Microwave/RF Engineer capable of applying commercial and in-house simulation tools for analysis and design in support of our national security missions. You will be responsible for using your engineering judgement and modeling experience for a wide variety of projects including the areas of: high-power microwave, antenna design, Radio Frequency (RF) Electromagnetics, and radar modeling. This position is in the Computational Electromagnetics Group of the Computational Engineering Division (CED), within the Engineering Directorate.

This position will be filled at either level depending on your qualifications.  Additional job responsibilities (outlined below) will be assigned if you are selected at the higher level.

In this role you will


  • Provide electromagnetics knowledge to interdisciplinary teams, work under general supervision, assist in determining own tasks and milestones, consult on experimental design, analyze, and recommend solutions, using industry-standard modeling tools such as Ansys HFSS and FEKO, and run and modify in-house simulation tools on world-leading supercomputers.
  • Contribute subject matter electromagnetics (EM) expertise to multidisciplinary teams.
  • Improve in-house parallel radar simulation tools for application to missile defense problems.
  • Develop computational tools and techniques for analyzing full-wave electromagnetics problems.
  • Organize and analyze data from research, present results at technical meetings and national conferences, and publish novel research results in peer-reviewed literature.
  • Provide engineering solutions for research projects with competing priorities, implement research concepts in a multidisciplinary team environment where commitments and deadlines are important to project success.
  • Conduct research in high frequency electromagnetics, radio frequency circuits, or wireless technology to enable the development of new state-of-the-art systems for Laboratory-relevant applications.
  • Perform other duties as assigned.

Additional job responsibilities, at the SES.3 level 

  • Serve as a project leader for analysis and design projects.
  • Balance management of multiple projects/tasks and priorities of customers to ensure deadlines are met.
  • Perform advanced research in at least one of the following areas: computational electromagnetics, radar modeling, and RF propagation modeling.


  • Ability to obtain and maintain a U.S. DOE Q-level security clearance which requires U.S. Citizenship.
  • Master’s degree in Engineering, Physics, or closely related field, or equivalent combination of education and related experience.
  • Experience with one or more of the following areas: high frequency electromagnetics/antenna design, radar system modelling, radio frequency circuits, wireless communications, wireless systems.
  • Experience in design, simulation, and experimental execution for electromagnetic/RF systems.
