Senior Software Engineer, Mapping & Localization

We are seeking a highly skilled and motivated Senior Software Engineer to join our Mapping & Localization team. In this role, you will be responsible for enhancing both the online and offline components of our mapping infrastructure, including online map interface, map version control, tile-based LiDAR map generation, and large-scale map management. You will play a critical role in supporting runtime map queries for key modules such as perception, localization, prediction, and planning.

Responsibilities

• Design and optimize scalable interfaces for online lane and map representation.
• Improve cross-module map interfaces to support perception, prediction, and planning pipelines.
• Develop and enhance systems for large-scale map deployment, including offline map generation, version control, and online tile-based LiDAR map loading.
• Maintain and evolve the mapping watchdog and event mining systems to monitor system health and anomalies.
• Enhance the mapping CI system to support robust development and deployment workflows.
• Optimize performance of offline 3D reconstruction pipelines.
• Collaborate closely with cross-functional teams to understand system-wide dependencies and performance needs across perception, planning, control, simulation, and infrastructure.
• Work with the operations team to define requirements for data collection, preprocessing, labeling, and validation.
• Ensure that your work is performed in accordance with the company’s Quality Management System (QMS) requirements and contribute to continuous improvement efforts.
• Ensure team compliance with QMS, monitor quality, and drive process improvements.

Required Skills

• BS or MS in Computer Science, Computer Engineering, or a related technical field.
• 3+ years of experience in developing large-scale, real-time C++ systems.
• Strong proficiency in modern C++ and understanding of multi-threading, multiprocessing, and operating systems, e.g. ROS.
