About The Position

BAE Systems is looking for a Principal Systems Engineer with a passion for engineering and the desire to be part of an innovative, dedicated team responsible for industry-leading Navigation products. Our team needs engineers interested in architecting, designing, and developing system designs for real-time embedded Navigation receivers for military ground, airborne, and weapons applications. This position offers abundant opportunities to acquire in-depth knowledge of Navigation technology and receiver architecture and apply that knowledge in a team effort to develop our Modernized Navigation receiver products. The Ground, Navigation, and Control (GNC) Systems Engineer is responsible for the design, development, integration, and validation of advanced navigation solutions for aerospace, defense, or autonomous platforms. This role focuses on developing robust algorithms and architectures that provide accurate and reliable state estimation under challenging, dynamic, and sensor ‑ limited environments.

Requirements
