Lead state estimation for autonomous aircraft at Ribbit in hybrid Burlington, Ontario, using modern C++ and probabilistic estimation techniques.

As a Senior State Estimation Engineer, you will shape architecture, guide design reviews, and maintain production code quality. Your work spans GNSS/INS integration, vision-based navigation, sensor fusion, and integrity monitoring. You will support reliable aircraft state estimates during degraded or unavailable satellite navigation.

Key Responsibilities

Lead state estimation stack architecture, roadmap, and design reviews

Develop estimators using Kalman filters and factor-graph methods

Fuse IMUs, GNSS, cameras, LiDAR, and aircraft sensors

Build fault detection, integrity monitoring, and quality metrics





Mentor junior engineers and represent estimation in reviews

Requirements

University degree in engineering, computer science, robotics, or related field

State estimation or navigation software experience on real hardware

Up-to-date C++ on Linux with Eigen and estimation libraries

Inertial navigation, GNSS/INS integration, and sensor calibration experience

Python or MATLAB experience for analysis and filter tuning

Apply state estimation, sensor fusion, and C++ expertise to autonomous aircraft systems at Ribbit.
