Lead state estimation and modern C++ development at Ribbit in a hybrid Greater Toronto Area role supporting autonomous aircraft field tests. As a Senior State Estimation Engineer, you will shape the estimation stack for autonomous airplanes. The work combines probabilistic estimation, GNSS/INS integration, sensor fusion, and vision-based navigation. You will collaborate with navigation, controls, hardware, and flight-test teams while mentoring junior engineers. Key Responsibilities:

Lead estimation architecture, roadmap, design reviews, and code quality Develop estimators for aircraft state, wind, air data, and terrain height Build GNSS-denied navigation using vision and alternative sensors Own aircraft sensor selection, calibration, synchronization,



and health monitoring Deploy quality metrics and integrity monitoring for downstream users Requirements:

Engineering, computer science, robotics, or related university degree State estimation or navigation software experience on real hardware Contemporary C++ on Linux with Eigen and estimation or vision libraries Experience with inertial navigation, GNSS/INS integration, and sensor calibration Eligibility for Government of Canada security clearance and Controlled Goods assessment Apply state estimation, C++, sensor fusion, and autonomous navigation expertise to Ribbit aircraft systems in the Greater Toronto Area.
