Senior Path Planning Engineer – Robotics Navigation

Neara; Singapore; On-site; SGD 120,000 - 180,000; Full time

Job summary

LionsBot in Singapore seeks a Senior Software Engineer specialized in path planning to advance navigation for autonomous cleaning robots. You will own the planning stack from high-level route planning to complete path generation.

We value strong foundations in motion planning, computational geometry, and optimization, plus hands-on ROS1/ROS2 on Linux, SLAM/Perception collaboration, and thorough testing. Join our fast-growing robotics scaleup shaping the future of intelligent cleaning solutions.

Qualifications

• Bachelor’s or Master’s degree in CS, Robotics, or a related field (or PhD with relevant focus).
• 3+ years of industry experience in navigation, motion or coverage planning.
• Strong proficiency in C++ and Python development on Linux.
• Hands-on experience with ROS1 / ROS2 and modern software engineering practices.
• Solid understanding of robot kinematics, dynamics, and map representations (occupancy grids, costmaps, graph maps).
• Deep understanding of graph and sampling-based global planners (A*, D*, RRT*, PRM, etc.).
• Experience with implementing complete coverage path planning algorithms.
• Familiarity with trajectory optimization and local planning frameworks (TEB, MPC, or similar).
• Familiarity with simulation tools (Gazebo, Isaac Sim, or RViz) for development and validation.
• Strong analytical mindset with excellent problem-solving and debugging abilities.
• Experience with learning-based or hybrid planning algorithms (e.g. reinforcement and imitation learning) is a bonus.
• Experience with optimizing software for embedded hardware (e.g., Jetson, ARM) or GPU-based acceleration is a bonus.

Responsibilities

• Design and implement global path planning algorithms for large-scale dynamic environments, ensuring optimal and collision-free routing across multi-floor indoor environments
• Develop and optimize complete coverage path planners tailored for cleaning robots
• Develop and maintain costmap and environment representations, integrating perception and SLAM inputs for accurate planning
• Develop and apply learning-based planning techniques (e.g. reinforcement and imitation learning) to enhance navigation adaptability and robustness in dynamic environments
• Develop comprehensive test cases for validating algorithms and software in both simulated and real-world environments, to ensure reliable performance.
• Maintain comprehensive documentation of all code implementations and test cases
