About the Job

Field AI is seeking a Robotics AI Engineer to help advance the sensor calibration systems that power our autonomous robots. As a member of our Calibration, Localization, and Mapping (CLAM) team, you will work alongside a highly focused group of engineers developing production-grade calibration pipelines for complex multi-sensor robotic platforms. Your work will span camera, LiDAR, IMU, and other sensor modalities, contributing to intrinsic, extrinsic, and temporal calibration workflows that enable reliable perception in real-world environments. Depending on your experience and interests, you'll improve automated calibration tooling, optimize large-scale sensor data processing, and develop robust calibration algorithms that support our downstream localization, mapping, and autonomy systems. The ideal candidate combines a strong foundation in robotics, computer vision, and 3D geometry with the practical engineering skills needed to build scalable, maintainable software in a fast-paced, collaborative environment.

What You Get To Do

• Develop and refine sensor calibration workflows for various sensor modalities (e.g., LiDAR, cameras, IMUs), including intrinsic, extrinsic and temporal calibration in online and offline settings.
• Design and implement scalable systems to manage and process large sensor datasets for calibration purposes, ensuring high reliability and performance.
• Implement and optimize algorithms in C++ and Python, maintaining a clean and organized code base.
• Explore and integrate emerging technologies and tools to enhance sensor calibration workflows.
• Collaborate with cross-functional teams to meet project-specific documentation requirements and deliverables.

What You Have

• Master's degree in Computer Science, Engineering, or a related field.
• 2+ years of work experience as a robotics software engineer, with expertise in robotics, computer vision and sensor calibration.
• Proficiency in C++ and Python, with a proven ability to write maintainable and efficient code.
• Solid background knowledge of 3D geometry and computer vision.
• Solid understanding of sensor calibration techniques (e.g., camera intrinsic calibration, LiDAR-Camera calibration, multi-sensor extrinsic calibration).
• Hands-on experience with sensor data processing tools and libraries such as PCL, Open3D, OpenCV, Kalibr, etc.
• Familiarity with Robot Operating System (ROS) and software development practices in Ubuntu.
• Familiarity with backend optimization tools and libraries such as Ceres, GTSAM, g2o.
• Strong problem-solving skills, attention to detail, and able to work independently while managing multiple priorities.
• Strong work ethic, highly self-motivated, and excellent written and verbal communication skills.

The Extras That Set You Apart

• Ph.D. in Computer Science, Engineering, or a related field.
• Research experience with publications in top-tier conferences or journals related to robotics, computer vision or machine vision.
• Familiarity with factory-level calibration procedures and tooling for high-volume product lines (e.g., drones, autonomous vehicles, AR/VR devices).
• Hands-on experience calibrating hundreds of camera intrinsics or camera-LiDAR systems at scale, including automated or semi-automated workflows.
