Job summary

Echodyne is seeking a Principal State Estimation Engineer to lead pose-estimation development for radar systems operating in GPS-denied environments. You will architect on-radar systems using radar and IMU data, and drive prototypes through production deployment, contributing to robust, field-ready solutions.

You will work across radar, signal processing, embedded software, and test teams to optimize system-level performance, with an emphasis on state-estimation theory, 3D geometry, and sensor

Qualifications

• Demonstrated ability to independently lead an open-ended technical problem.
• Experience developing state-estimation, localization, navigation, perception, or machine learning solutions for robotics, VR/AR headsets, autonomous vehicles, drones, aerospace, or similar platforms from prototype through production deployment.
• 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.
• Strong verbal and written communication skills.

Responsibilities

• Lead development of methods for estimating radar position, velocity, orientation, angular rate, and height above ground in GPS-denied environments using radar and IMU data, terrain maps, and other on-radar sensors and data.
• Apply techniques from robotics and autonomy, including SLAM, odometry, inertial navigation, localization, factor graphs, probabilistic state estimation, and machine learning – within the constraints of an embedded real-time system.
• Take these algorithms from research and prototyping through production implementation.
• Drive system-level impacts and coordinate with other teams on deployment.
• Work with radar, signal processing, embedded software, systems, and test teams to integrate capabilities into products.
• Analyze field data to characterize performance and identify failure modes to produce robust, production-grade solutions.
