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
- Up-to-date 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.
