Senior Mapping Engineer (Large-Scale HD Mapping) - First Key Hire Circa £80k+, London based

Want to work for an advanced start up building real-world autonomous systems? We're looking for a highly skilled Senior Mapping Engineer to become the first dedicated mapping lead. This is a high-ownership role where you'll take charge of the high-accuracy, large-scale mapping capability, set the technical roadmap, and grow and mentor a mapping team as deployments scale. You'll maintain and evolve an existing mapping codebase, enhancing accuracy, stability, and scalability across challenging industrial and autonomous environments. Working closely with perception, localization, and navigation, you'll ensure themaps are drift-free, up-to-date, and deeply integrated into the autonomy stack-from raw sensor data to validated, deployed map products. What you'll do * Own and advance scalable LiDAR- and vision-based mapping pipelines. * Build and improve 2D/3D representations: occupancy grids, vector/HD maps, semantic layers, environment models. * Lead multi-sensor fusion (LiDAR, cameras, radar, GNSS/INS, odometry) into coherent, consistent map outputs. * Deliver large-scale capabilities like multi-session mapping, fleet workflows, map versioning, delta updates, and distributed map generation. * Maintain tight integration with SLAM/Localization to ensure stable, drift-free deployment performance. * Define KPIs and validat...
