Software Engineer, Decision & Planning Algorithm (Robotics)

Job Description Get to Know the Team The Robotics Technology team is a core part of Lumen Dynamics's long-term vision to build urban embodied AI. Our engineers take full ownership of the product lifecycle: designing and manufacturing hardware in-house, developing control and machine‑learning systems, and rigorously testing in real-world conditions and production fleet operations. This is a fast-moving, multidisciplinary environment where software, hardware and data science experts collaborate to solve practical challenges at scale. We are executing an ambitious growth plan to expand our robotics fleet across cities over the coming years. We are focused on delivering highly productive, safe, and efficient robot delivery services that help address current delivery labor shortages. Based in Singapore and China, we offer opportunities to work on the latest autonomy, deploy solutions in complex environments, and directly influence the future of last‑mile logistics. If you're excited by tangible impact, large-scale systems and cross-functional engineering, you'll find meaningful challenges and rapid career growth here. Get to Know the Role You will contribute to decision and planning algorithms for indoor and outdoor, full-scenario delivery robots. As a senior engineer, you will: Develop an understanding of planning approaches and where they apply; Take part in scenario breakdown, algorithm design discussions, and implementation; Debug issues in simulation and on-vehicle tests, measure performance after release, and drive continuous improvement. We look for solid theory, engineering execution, and high-quality delivery. You will work onsite at Lumen Dynamics office. The Critical Tasks You Will Perform Help design global routing and decision & motion planning systems that are safe and efficient while maintaining ride quality. Research and advance full-scenario driving on urban public roads and semi-enclosed campus roads, including structured and unstructured roads, signalized and unsignalized intersections, crosswalks, dynamic conditions (congestion, construction), and queueing in large dispatch areas. Research and improve nonlinear, multi-objective planning in unstructured indoor settings: tight spaces, elevators, and dense pedestrian flows. Contribute to quantitative metrics and a data closed loop , and expand automated test coverage. Contribute to data-driven , end-to-end planning R&D and scenario optimization. Qualifications What Essential Skills You Will Need Master's degree or above in Computer Science, AI, applied math, automotive engineering, or a related field; 3–5 years of R&D experience planning algorithms for autonomy or robotics. Solid C++ ; proficient Python and Linux ; experience with ROS / ROS2 or Apollo / Autoware . Demonstrated proficiency in leveraging AI tools and systems to drive efficiency and innovative problem-solving Algorithms Solid knowledge of classical decision and planning methods (e.g. Lattice, DP/QP, Hybrid A*, POMDP-style approaches). Hands-on experience with joint lateral–longitudinal planning in real scenarios. 3+ years of experience with decision and planning under game-theoretic or interactive settings. Familiarity with ML for planning (e.g. imitation learning, reinforcement learning). Experience innovating for real-world constraints. Domain Familiarity with layered autonomous driving planning stacks. Experience with how upstream modules affect planning and how to measure trajectory quality. Tools & simulation Use CARLA , NVIDIA Isaac (including Isaac Sim / Isaac Lab, etc.) or comparable platforms for algorithm validation. On-vehicle debugging and log analysis. Nice to have Publications at top venues (e.g. ICRA, IROS, IV, CVPR). Experience shipping end-to-end planning to production or field trials.
