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 monitoringResearch methods resisting GNSS jamming, spoofing, and outagesBuild estimator quality metrics for downstream system usersImplement innovation gating, cross-checks, and integrity monitoringCollaborate with navigation,



controls, hardware, and flight-test teamsRequirements:
Degree in aerospace, electrical, mechanical, software, or robotics engineeringModern C++ and Linux experience with EigenKnowledge of factor graphs, optimization, observability, and covariance tuningSensor integration experience, including intrinsic, extrinsic, and time calibrationEligibility for Reliability or Secret security clearance and Controlled Goods assessmentUse robotics, C++, sensor calibration, and integrity-monitoring expertise to strengthen Ribbit’s autonomous aircraft state estimates.
