Software Defined Radio Engineer

Date: Sep 16, 2023

Location: Oak Ridge, TN, US, 37830

Company: Oak Ridge National Laboratory

Requisition Id 9632 

Level: RP02


The Geospatial Science and Human Security Division (GSHSD) is looking for new team members to be a part of our challenging and exciting projects in the area of secure/robust communications research. We focus on developing solutions that utilize artificial intelligence and machine learning that optimize communications in complex RF environments in near real time. Our projects involve working with protocol development, embedded systems technology, software-defined radios, and RF over fiber to provide a wide range of research opportunities and reach a broad array of sponsors.  The Resilient Communications group at ORNL has also just recently installed a ground station for space to ground communication development solutions thus providing an avenue for new and exciting opportunities involving satellite communications.  ORNL is the home to the fastest supercomputer in the world, which allows our group to create complex simulations, such as of 5G environments, on HPC supercomputers giving us an edge over many other research institutions.


ORNL’s Resilient Communications group is seeking candidates that would like to participate in the wide array of RF projects and opportunities that we have at the lab. While experience in most of the areas listed below is ideal, anyone that has the drive to want to be a part of the projects listed above and has just some experience in the responsibilities listed below are encouraged to apply. Beyond the technologies our group works on, the lab is full of subject matter experts that are constantly involved in unique and complex problems that we help solve through hardware and software solutions.


Main job responsibilities for the position include working with a team that:

  • Performs RF signal reception and transmission of data using various antenna and modulations schemes (FSK, PSK, QAM, etc.).
  • Uses machine learning and artificial intelligence to develop phy layer solutions
  • Provides specific input to software and hardware components of system design, including hardware/software trade-offs, software reuse, use of Commercial Off-the-shelf (COTS) in place of new development, and requirements analysis and synthesis from system level to individual software components.
  • Supports real-world test operations and developing bench test procedures
  • Attends and presents design reviews. Working in both classified and unclassified settings and on a wide variety of applied areas.


We are primarily seeking a candidate that is driven and wants to work on solving hard problems that utilize RF systems. A few of the essential qualifications are listed below followed by a list of desired but not required qualifications.
