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.
