Role Overview

The Robotics Software Engineer will focus on designing and refining the mobility stack for a differential-drive service robot that functions in dynamic indoor settings. The role demands expertise in programming and hands-on experience addressing localization, navigation, motion control, and obstacle avoidance challenges in practical environments.

Key Responsibilities

• Create robust robotics software using ROS 2, C++, and Python languages.
• Develop and optimize SLAM, localization, Nav2, path planning, motion control, costmaps, obstacle avoidance, and recovery mechanisms.
• Integrate sensors such as LiDAR, depth cameras, IMUs, wheel encoders, and motor controllers into the system.
• Tackle issues including odometry drift, TF inaccuracies, loss of localization, motion oscillation, blocked navigation paths, and failures in planning or control modules.
• Ensure safe navigation that smoothly handles interactions with people, furniture, narrow pathways, and moving obstacles.
• Conduct performance testing and validation on actual robot hardware.
• Work collaboratively with teams from embedded systems, electronics, mechanical engineering, and product management areas.

Required Qualifications

• Hands-on experience with ROS 2, Linux environments, Nav2 stack, C++, and Python programming.
• Comprehensive understanding of differential-drive kinematics, odometry, TF2, URDF formats, SLAM, localization techniques, sensor fusion, and feedback control systems.
• Competence in troubleshooting robot behaviors using RViz, rosbag recordings, log files, and authentic sensor data.
• A degree in Robotics, Mechatronics, Computer Science, Electronics, Electrical Engineering, or a related discipline; equivalent work experience may be considered.

Mandatory Project Experience

• Completed at least one substantial physical project involving mobility or autonomous navigation of a differential-drive robot, autonomous mobile robot (AMR), automated guided vehicle (AGV), or service robot.
• Direct involvement in developing, integrating, tuning, or debugging significant mobility features within the project.
• Note that simulation-only backgrounds are not acceptable.

Preferred Experience

• Familiarity with ROS 2 distributions such as Jazzy or Humble, SLAM Toolbox, AMCL, robot_localization package, and utilizing Nav2 behavior trees.
• Experience with hardware platforms like NVIDIA Jetson, RPLIDAR sensors, Intel RealSense cameras, CAN bus communication, and embedded motor controllers.
• Practical knowledge navigating robots in crowded or varying indoor environments.

Application Instructions

Applicants should provide detailed information on at least one mobile robot project they have contributed to, explaining their role, the problems they addressed, results achieved, and include links or videos demonstrating their work if available.
