Autonomous 3D Pipeline Navigation Engineer

Bonbon-X Limited; Hong Kong; On-site; HKD 520,000 - 780,000; Full time

Job summary

Bonbon-X Limited in Hong Kong is seeking an R&D Software Engineer to develop automated 3D navigation for underground pipeline robotics. You will contribute to localization, mapping, 3D reconstruction, and real-time telemetry within GPS-denied environments.

You will work with Python and C++ in ROS/ROS2-based frameworks, integrate sensors including LiDAR, IMU, cameras, and edge devices, and participate in field trials to validate navigation accuracy and system reliability.

Qualifications

• Bachelor’s degree or above in Engineering, Applied Physics, Robotics, Computer Science, Electronic Engineering, Mechanical Engineering, Mechatronics, or related STEM.
• Experience in robotics software development, embedded systems, sensor integration, automation, or robotic control.
• Knowledge of Python and / or C++ programming.
• Experience with Linux-based development environments.
• Familiarity with ROS / ROS2, SLAM, robot navigation, mobile robots, AGV systems, LiDAR, camera systems, IMU, Raspberry Pi, Jetson, ESP32, Arduino, or similar platforms would be an advantage.
• Ability to conduct experiments, analyse technical problems, document engineering results, and support real-world system testing.

Responsibilities

• Research and develop automated 3D navigation methods for pipeline inspection robots in confined, GPS-denied environments.
• Study and implement sensor fusion using wheel odometry, IMU, camera, LiDAR, depth sensor, encoders to estimate position and pipe geometry.
• Develop software modules for localisation, mapping, path tracking, 3D trajectory reconstruction, obstacle detection, and navigation decision support.
• Evaluate ROS / ROS2 navigation frameworks and their applicability to Bonbon-X’s pipeline robot.
• Build Python / C++ tools for robot control, data acquisition, live monitoring, sensor calibration, and field-test diagnostics.
• Develop real-time data streaming and visualisation tools for movement status, sensor readings, and navigation data.
• Support integration of edge computing platforms, embedded controllers, sensors, and communication modules.
• Design and conduct lab experiments to validate navigation accuracy and system performance.
• Participate in field trials, analyze failures, and propose improvements.
• Prepare technical documentation and progress reports for internal review and reporting.
