Own sensor fusion for Ribbit’s autonomous aircraft near Toronto, developing integrity-aware estimators with C++, Linux, and diverse onboard sensors.
Ribbit seeks a senior robotics engineer to advance the sensor suite and state-estimation stack for uncrewed airplanes. You will investigate sensor selection, calibration, timing, health monitoring, and navigation without dependable GNSS. The position combines hands-on production development with analysis of estimator quality, fault detection, and protection levels.
Key Responsibilities: Own sensor selection, calibration, timing, and aircraft health monitoring
Research methods resisting GNSS jamming, spoofing, and outages
Build estimator quality metrics for downstream system users
Implement innovation gating, cross-checks, and integrity monitoring
Collaborate with navigation,



controls, hardware, and flight-test teams
Requirements: Degree in aerospace, electrical, mechanical, software, or robotics engineering
Contemporary C++ and Linux experience with Eigen
Knowledge of factor graphs, optimization, observability, and covariance tuning
Sensor integration experience, including intrinsic, extrinsic, and time calibration
Eligibility for Reliability or Secret security clearance and Controlled Goods assessment
Use robotics, C++, sensor calibration, and integrity-monitoring expertise to strengthen Ribbit’s autonomous aircraft state estimates.
