Responsibilities for this Position

ROLE AND POSITION OBJECTIVES:

We are seeking a highly skilled Navigation Fusion Engineer with expertise in Kalman filtering and cutting-edge sensor fusion techniques for GPS-denied environments. This role will contribute to the development and integration of navigation solutions for Unmanned Aerial Systems (UAS), Unmanned Ground Vehicles (UGV), and precision-guided munitions. You will design, implement, and optimize state estimation algorithms across a range of hardware and mission profiles.

Key Responsibilities

• Design and implement advanced sensor fusion algorithms using Extended Kalman Filters (EKF), Unscented Kalman Filters (UKF), and Nonlinear Observers.
• Develop and refine tightly coupled and loosely coupled navigation solutions integrating IMU, odometry, vision (VIO/SVO), LiDAR, magnetometers, and barometers.
• Evaluate and deploy factor graph-based SLAM and probabilistic inference frameworks (e.g., GTSAM, iSAM2) for persistent localization in GPS-denied environments.
• Contribute to algorithm development for multi-sensor fusion frameworks, including Deep Learning-Augmented Inertial Navigation, event-based sensors, and semantic fusion.
• Conduct performance evaluations under degraded or denied GNSS conditions, including urban canyons, subterranean, and electronic warfare environments.
• Work cross-functionally with autonomy, guidance, perception, and embedded software teams.
• Develop and support simulation frameworks (e.g., Gazebo, AirSim, ROS2) for testing navigation systems in virtual environments.

Required Qualifications

• 10+ years of experience in navigation algorithm development with proven track record on deployed systems.
• Expert in Kalman Filter variants (EKF, UKF, IEKF, Particle Filters) and modern Bayesian estimation methods.
• Strong experience with GNSS-denied navigation techniques including:
  • Visual-Inertial Odometry (VIO/SVO)
  • LiDAR-Inertial Odometry (LIO)
  • DVL integration (for maritime)
  • Zero-velocity updates (ZUPT) for foot-mounted or stationary UGVs
  • Cooperative Localization / SWaP-C-constrained fusion for munitions
• Proficiency with C++ and Python in real-time or embedded systems.
• Familiarity with ROS/ROS2, GTSAM, NavFusion engines like NavVis, u-blox, and VectorNav SDKs.
• Experience in hardware-in-the-loop (HIL) testing and integration with real-time operating systems (RTOS).

Preferred Qualifications

• Experience with:
  • Factor Graph optimization, graph-SLAM, and incremental smoothing (iSAM2)
  • Deep learning-enhanced navigation (e.g., DeepVO, LSTM-IMU fusion)
  • Event-based camera fusion
  • Cold-start estimation and initialization robustness
• Knowledge of STAN, BayesOpt, or GP-based estimation for adaptive sensor tuning.
• Publications or patents in navigation, estimation theory, or multi-sensor fusion.

Our Commitment to You:

• An exciting career path with opportunities for continuous learning and development.
• Research oriented work, alongside award winning teams developing practical solutions for our nations security
• Flexible schedules with every other Friday off work, if desired (9/80 schedule)
• Competitive benefits, including 401k matching, flex time off, paid parental leave, healthcare benefits, health & wellness programs, employee resource and social groups, and more
