Role summary
Leidos is seeking a Signal Processing Engineer to support Electronic Warfare (EW) programs in Arlington, VA or San Diego, CA. The role involves improving sensor and signal robustness in complex environments, advancing research in EW applications, and developing, modeling, and testing algorithms using tools like Matlab, Simulink, and C++. Responsibilities include analyzing simulation and real-world data, participating in testing, and engaging with customers. The position requires a Bachelor's degree in a related field, 4+ years of radar signal processing experience, fluency in relevant tools and languages, and knowledge of core signal processing concepts. A U.S. Citizenship and active Secret clearance are mandatory.
Today, Electronic Warfare (EW) is a growing enterprise - protecting the warfighter and our national security against ever-adapting threats. The Electronic Warfare Divison at Leidos currently has an opening for a Signal Processing Engineer to support EW programs in Arlington, VA or San Diego, CA.
As part of our team, you will focus on improving the robustness and efficacy of sensors and signals in complicated environments. More broadly, you will advance the state of the art in research and advanced applications to support ongoing and future EW programs. You’ll simultaneously get to work alongside scientists and experts in these fields to help grow your own knowledge and career; motivated candidates may have an opportunity to lead tasks as well.
Regular tasks will include:
- Develop, model, and test algorithms in Matlab, Simulink, or C++
- Analyze results from simulation or real data to identify root causes and trends
- Develop novel and advanced algorithms, performance simulation, and analysis - using simulated and real data in both time series and spectral domains
- Participate in lab-based and field testing
- Support marketing and business development initiatives
- Engage in multiple projects, interacting with Customers as well
