Lead aircraft state estimation at Ribbit in a hybrid Burlington role, applying contemporary C++ and probabilistic navigation to autonomous airplanes. As a Senior State Estimation Engineer, you will shape estimation architecture, guide design reviews, and develop reliable aircraft-state solutions. The work covers GNSS/INS integration, vision-based navigation, sensor fusion, and integrity monitoring. You will collaborate with navigation, controls, hardware, and flight-test teams while supporting production systems on real aircraft. Key Responsibilities:

Lead state estimation architecture, roadmap, design reviews, and code quality Develop estimators for degraded or denied GNSS conditions Own aircraft sensor selection, calibration, synchronization, and health monitoring Write, review,



and test production C++ for aircraft systems Mentor junior engineers and represent estimation in cross-team reviews Requirements:

University degree in engineering, computer science, robotics, or related field State estimation or navigation software experience on real hardware Modern C++ on Linux with Eigen and estimation or vision libraries Experience with probabilistic estimation, inertial navigation, and GNSS/INS integration Eligibility for Government of Canada security clearance and Controlled Goods assessment Apply aircraft estimation, sensor fusion, C++, and navigation expertise to Ribbit’s autonomous aviation systems in Burlington.
