Lead aircraft state estimation at Ribbit in a hybrid Burlington role, applying up-to-date 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 qualityDevelop estimators for degraded or denied GNSS conditionsOwn aircraft sensor selection, calibration, synchronization, and health monitoringWrite, review,



and test production C++ for aircraft systemsMentor junior engineers and represent estimation in cross-team reviewsRequirements: University degree in engineering, computer science, robotics, or related fieldState estimation or navigation software experience on real hardwareModern C++ on Linux with Eigen and estimation or vision librariesExperience with probabilistic estimation, inertial navigation, and GNSS/INS integrationEligibility for Government of Canada security clearance and Controlled Goods assessmentApply aircraft estimation, sensor fusion, C++, and navigation expertise to Ribbit’s autonomous aviation systems in Burlington.#J-18808-Ljbffr
