## About the role

In this role, you’ll lead development of pose-estimation capabilities for Echodyne radars operating in GPS-denied environments. You’ll architect and develop new on-radar systems that use radar and inertial sensor data to estimate the global position and motion of radars without reliance on external navigation systems.

## What they're looking for

- Demonstrated ability to independently lead an open-ended technical problem
- Experience working with real-world spatial sensor data (e.g. camera, lidar, radar, ultrasound, sonar)
- Experience with SLAM, Kalman filtering, Bayesian estimation, and factor graphs
- Deep understanding of state-estimation theory, 3D geometry, coordinate transformations, rotations, and kinematics
- Strong foundations in linear algebra, probability, statistics, and optimization
- Strong software development skills in C++ and either Python or MATLAB
