Principal Navigation Systems Architect (PN&T)

Key Responsibilities

• Design and develop PNT solutions, including GNSS-based systems, inertial navigation, vision-based navigation, and multi-sensor fusion architectures.
• Analyze and improve positioning, navigation, and timing performance under diverse operational environments (e.g., GNSS-denied, urban canyon, RF-challenged).
• Develop, tune, and validate navigation algorithms, including Kalman filters, tightly/loosely coupled fusion, integrity monitoring, and error-state modeling.
• Model and simulate PNT systems to predict performance, assess sensor trade-offs, and support system design decisions.
• Conduct GNSS signal analysis, including interference, spoofing detection, multipath characterization, and resilience enhancement.
• Lead integration and testing in laboratory and field environments using representative sensors and platforms.
• Support system architecture development, providing expert input on PNT requirements, interfaces, and performance budgets.
• Collaborate with cross-functional teams, including hardware, software, autonomy, guidance & control, and systems engineering.
• Document and communicate findings, presenting test results, performance analyses, and recommendations to technical and non-technical stakeholders.

Required Qualifications

• Bachelor’s, Master’s, or PhD in Electrical Engineering, Aerospace Engineering, Robotics, Computer Science, Physics, or a related field.
• 10+ years of experience in PNT, navigation systems, or related domains.
• Strong understanding of: GNSS (GPS, Galileo, GLONASS, BeiDou) and augmentation systems (SBAS, RTK, PPP); Inertial sensors (IMUs), magnetometers, barometers, wheel odometry, etc.; Navigation and sensor-fusion algorithms (EKF/UKF, error-state filtering, SLAM); Timing systems (oscillators, synchronization, clock modeling).
• Proficiency with simulation and analysis tools (e.g., MATLAB, Python, C/C++, ROS).
• Experience with real-world data collection, calibration, and system testing.
• Strong problem-solving ability and communication skills.
• US Citizenship required.

Preferred Qualifications

• Experience with GNSS-denied navigation (vision, lidar, RF, UWB, pseudolites).
• Experience with autonomous vehicles, aerospace, robotics, defense, or maritime navigation.
• Knowledge of signal processing, RF systems, or GNSS receiver internals.
• Familiarity with certification or compliance standards (e.g., DO-229, DO-253, RCTA/DO-178, ISO 26262).
• Experience developing resilient PNT systems, including anti-jamming and anti-spoofing techniques.
