Guidance, Navigation, and Control Principal Systems Engineer

Job Description

Because this role involves a combination of collaborative/in-person and independent work, it will take the form of a hybrid work format, with time split between working onsite and remotely.

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 sensorlimited environments.

Key Responsibilities

• Develop and implement navigation algorithms using multisource sensor fusion, combining data from inertial sensors, GPS/GNSS, vision systems, radar, and other external aids.

• Design, tune, and optimize Kalmanfilterbased estimators, including EKF, UKF, CKF, and advanced nonlinear filtering methods.

• Architect and analyze inertial navigation systems (INS), including strapdown integration, sensor error modeling, bias/scale factor estimation, and drift compensation.

• Perform system modeling, simulation, and analysis of navigation and guidance performance under varying mission scenarios.

• Integrate navigation algorithms into embedded realtime systems and support software verification, validation, and hardwareintheloop testing.

• Collaborate with crossfunctional teams in GNC, autonomy, avionics, and systems engineering to ensure seamless integration of navigation subsystems.

• Conduct trade studies and performance analyses to evaluate sensor configurations, filter approaches, and navigation architectures.

• Document requirements, interface specifications, algorithm designs, and test results to support certification and product development.

Required Education, Experience, & Skills

• Bachelor's degree in Science, Technology, Engineering, or Math (STEM) discipline, and 6 plus years of direct related experience.

• Must be a US Citizen.

• Have the ability to obtain a DoW Security Clearance.

• Strong expertise in multisensor fusion techniques for navigation and state estimation.

• Deep understanding of inertial navigation principles, IMU error sources, INS mechanization, and inertial alignment methods.

• Proficiency in Kalman filtering and its variants for linear and nonlinear estimation problems.

• Experience with navigation system modeling, simulation environments, and performance analysis.

• Familiarity with aerospace or autonomous system GNC frameworks and realtime implementation constraints.

• Strong programming skills in languages typically used for algorithm development (e.g., C , Python, MATLAB).

• Ability to interpret sensor data, analyze system behavior, and diagnose estimation issues through statistical and signalprocessing methods.

• Effective communication skills for explaining complex technical topics to multidisciplinary teams.

• Experience working with software and systems engineering processes

• Experience with leadership as a part of program execution

• Experience with real-time embedded hardware systems

• A working knowledge of Communication Systems, Digital Signal Processing, or Radio Frequency Filtering

Preferred Education, Experience, & Skills

• Masters or PhD degree in Science, Technology, Engineering, or Math (STEM) discipline, and 6 plus years of direct related experience.

• Secret Clearance

• Experience with Jira and DOORS

• Experience or interest in utilizing AI tools for system development

• Experience with Model-Based System Engineering (MBSE) tools (CAMEO, SysML, MagicDraw, etc.)
