Northrop Grumman Northrop Grumman · Aerospace · Rolling Meadows, IL +1 · Systems/Architecture/Test

Northrop Grumman is seeking a Principal/Sr. Principal Systems Design Engineer to coordinate across disciplines, define system requirements and design, support trade studies, and guide decision-making using MBSE methods and tools like DOORS. The role involves working with subject matter experts and potentially applying AI/ML to RF classification, spectrum analysis, or adaptive beamforming.

What you'd actually do

  1. Systems Design Engineers coordinate across disciplines to ensure the system requirements and design are properly and thoroughly defined and captured.
  2. Tasking can include working with subject matter experts to decompose requirements, supporting trade studies of technical challenges, and guiding system design decision-making.
  3. System Design Engineers use Model Based Systems Engineering (MBSE) methods and tools, generate and update specifications and Verification Cross Reference Matrices (VCRM) in DOORS.
