Lead state estimation for autonomous aircraft at Ribbit in hybrid Burlington, Ontario, using modern C++ and probabilistic estimation techniques.
As a Senior State Estimation Engineer, you will shape architecture, guide design reviews, and maintain production code quality. Your work spans GNSS/INS integration, vision-based navigation, sensor fusion, and integrity monitoring. You will support reliable aircraft state estimates during degraded or unavailable satellite navigation.
Key Responsibilities: Lead state estimation stack architecture, roadmap, and design reviews
Develop estimators using Kalman filters and factor-graph methods
Fuse IMUs, GNSS, cameras, LiDAR, and aircraft sensors
Build fault detection, integrity monitoring, and quality metrics




Mentor junior engineers and represent estimation in reviews
Requirements: University degree in engineering, computer science, robotics, or related field
State estimation or navigation software experience on real hardware
Contemporary C++ on Linux with Eigen and estimation libraries
Inertial navigation, GNSS/INS integration, and sensor calibration experience
Python or MATLAB experience for analysis and filter tuning
Apply state estimation, sensor fusion, and C++ expertise to autonomous aircraft systems at Ribbit.
