## Description

We offer the opportunity to join a high-performing team solving problems and driving new solutions into next generation radar systems and air superiority platforms from development to production. Qualified candidates will apply strong systems engineering knowledge and understanding in the areas of target tracking, state estimation, and sensor fusion, working with various systems, hardware, and software teams. We encourage our engineers to be innovative with solving problems and identifying improvements.

This position requires up to 100% on-site

What You'll get to Do:

This position is primarily engaged in the development and fielding of target tracking and sensor fusion systems for advanced multi-function RF subsystems. Key features of operation include analyzing, shaping, and relating data from a wide variety of modes, such as: long-range search and track Radar waveforms and electronic surveillance measure returns.

Early in the system lifecycle, Principal systems engineers develop parametric representations, visualizations and data driven analysis to support sensor requirements definition and use case validation. Progressing past analysis and design, Northrop Grumman Systems Engineers also support the integration of sensor modes and trackers from digital simulation environments to sensor labs to our on-site fleet of specially modified test aircraft. Throughout this process, our AMS Systems Engineers engage with our customers to balance their functional and performance requirements with other sensor functionality to enable true multi-function operation.

 * Operates as a core individual contributor responsible for the sustained performance and minor adaptation of established algorithms and systems.
 * Execute technical tasks under general supervision, focusing on maintaining existing functionalities and making incremental improvements within clearly defined boundaries.
 * Ensures current systems meet performance objectives by leveraging existing documentation, such as defined Interface Control Documents (ICDs).
 * Utilize foundational skills in MATLAB and C++ for basic analysis and code modifications.
