Job summary

Asiacruit is seeking a SLAM & Spatial Navigation Engineer to develop real-time localization, mapping, and navigation for autonomous quadruped robots in GPS-denied environments. You will work on 3D LiDAR-based SLAM, sensor fusion, and ROS 2 navigation using Nav2 to enable reliable indoor and outdoor operation.

The role focuses on perception, mapping, localization, and motion planning for legged robots, accounting for terrain, elevation, and robot dynamics in real-world settings.

Qualifications

• Bachelor's or Master's degree in Robotics, Computer Science, Electrical Engineering, Mechanical Engineering, or a related technical field.
• Approximately 4–6 years of relevant experience in SLAM, robotics localization, autonomous navigation, or robotic perception.
• Strong programming skills in C++ and practical experience developing robotics software.
• Hands-on experience with 3D LiDAR-based SLAM and LiDAR-inertial odometry.
• Experience with one or more SLAM frameworks, such as LIO-SAM, Faster-LIO, Cartographer, or comparable solutions.
• Practical experience with ROS 2 and navigation frameworks such as Nav2.
• Familiarity with point cloud processing using PCL or similar libraries.
• Understanding of sensor fusion, IMU integration, localization drift, and mapping optimization.
• Knowledge of GTSAM, factor graphs, pose-graph optimization, or related estimation techniques is an advantage.
• Understanding of path planning, costmaps, terrain mapping, and traversability analysis.
• Experience with quadruped robots, legged robotics, or navigation across uneven terrain is a plus.
• Strong analytical and debugging skills, with the ability to validate algorithms in real-world robotic systems.

Responsibilities

• Develop and optimize real-time 3D LiDAR-inertial odometry and mapping systems for GPS-denied indoor and outdoor environments.
• Implement and evaluate SLAM frameworks such as LIO-SAM, Faster-LIO, Cartographer, or other suitable LiDAR-based mapping solutions.
• Process and analyze 3D point clouds using the Point Cloud Library (PCL) and related perception tools.
• Integrate LiDAR, inertial measurement units (IMUs), and other relevant sensors to improve localization accuracy and mapping robustness.
• Configure, integrate, and tune ROS 2 navigation stacks, including Nav2, for autonomous robotic navigation.
• Integrate semantic and topological costmaps from perception and AI systems to support environment-aware path planning.
• Develop sensor fusion and localization correction methods using available infrastructure references, static camera anchors, or known environmental markers.
• Design and optimize local path planners that account for quadruped robot dynamics, uneven terrain, and elevation maps.
• Generate and maintain terrain representations that support traversability analysis and safe navigation across complex surfaces.
• Evaluate localization drift, mapping accuracy, navigation performance, and system reliability through simulation and real-world testing.
• Troubleshoot mapping and navigation failures, optimize system performance, and improve robustness under changing environmental conditions.
• Collaborate with robotics controls, perception, VLA, and embedded systems engineers to integrate navigation capabilities into autonomous robotic platforms.

About Asiacruit

At Asiacruit, we connect top talent with forward-thinking organizations across industries. Our mission is to help businesses grow through smart, strategic, and people-focused solutions. We support companies by providing high-quality talent for local and global markets.

Position Overview

We are looking for a SLAM & Spatial Navigation Engineer to develop real-time localization, mapping, and navigation systems for autonomous quadruped robots operating in complex environments, including areas where GPS signals are unavailable or unreliable.

You will work on 3D LiDAR-based simultaneous localization and mapping (SLAM), sensor fusion, and autonomous navigation using ROS 2. Your work will help robots understand their surroundings, estimate their position, build accurate maps, and navigate uneven terrain while accounting for the movement and physical constraints of legged robotic platforms.

This role combines robotics perception, spatial mapping, localization, and motion planning, with a focus on reliable navigation in real-world indoor and outdoor environments.

Key Responsibilities

• Develop and optimize real-time 3D LiDAR-inertial odometry and mapping systems for GPS-denied indoor and outdoor environments.
• Implement and evaluate SLAM frameworks such as LIO-SAM, Faster-LIO, Cartographer, or other suitable LiDAR-based mapping solutions.
