Job Description
Looking for an opportunity to make an impact?
We’re hiring RF Seeker Engineers at multiple levels.
Leidos Defense Sensors is seeking multiple RF Seeker Engineers across various experience levels to join our Sensor Research and Analysis Division. Our division supports a wide range of research, development, and operational efforts, including radar design, hardware builds, algorithm development, software development, and HWIL testing and analysis.
In these roles, the selected candidates will primarily support the division’s algorithm development efforts with a focus on RF seeker signal‑processing capabilities and concepts of operations. They will maintain familiarity with the fielded systems our division supports, investigate cutting‑edge RF seeker technologies, and develop studies that inform our customers about emerging seeker advancements. These studies will typically include provisional MATLAB modeling, closed‑loop simulation, and validation on radar hardware.
The selected candidates will also present progress and study findings to Government and prime‑contractor stakeholders and collaborate closely with division teams on broader radar development and testing activities.
Your greatest work is ahead!
