Senior Mapping Localization Engineer

Responsibilities

Voxelmaps builds spatial intelligence systems that transform large-scale sensor data into accurate, usable geospatial and mapping products. We are seeking a Senior Mapping & Localization Engineer to enhance and develop core algorithms and infrastructure for localization, sensor alignment, camera geometry, and spatial data integration workflows in Oxford, UK
. This role focuses on improving map consistency and accuracy across large capture datasets by solving problems in SLAM loop closure, point cloud registration, sensor fusion, camera calibration, and coordinate system transformations
. You will work at the intersection of robotics, photogrammetry, computer vision, and geospatial systems.

• Enhance existing or design and implement new SLAM pipelines to improve global trajectory consistency and reduce drift across large-scale mapping datasets collected from different sources.
• Improve localization robustness across multi-session and multi-sensor capture systems.

• Improve point cloud registration pipelines for LiDAR and multi-modal datasets.
• Develop workflows for cross-session map alignment and map merging.

• Improve and develop sensor fusion pipelines integrating LiDAR, cameras, GNSS, IMU, odometry, and external references.
• Implement temporal synchronization and uncertainty-aware fusion methods.
• Integrate third-party spatial datasets and external map sources into Voxelmaps mapping pipelines.

• Design and maintain coordinate transformation frameworks across different coordinate systems.
• Implement georeferencing and transformation validation workflows.
• Support spatial accuracy assessment and error analysis.

• Maintain and optimize camera calibration and camera pose optimization pipelines.
• Improve trajectory accuracy through joint optimization of sensor geometry and pose estimates.

• BS / MS in Computer Science, Robotics, Geomatics, Photogrammetry, Mathematics, or related field.
• 5+ years of experience in robotics, mapping, computer vision, or geospatial systems.
• Strong background in SLAM, localization, sensor fusion, geometric optimization, and 3D reconstruction.
• Strong C++ and Python skills.
• Experience with numerical optimization and geometry libraries.

Voxelmaps Inc. was originally a spin-off from Navmii, one of the leading navigation and mapping companies in the world. Voxelmap’s mission is to build a true 4D volumetric model of the planet, combining visual, spatial and temporal data to create the most detailed map of the world. It does this using a unique patent-pending technology using MRVOGs (Multi-Resolution, Voxel Occupancy Grids).

The company is headquartered in Austin, Texas, USA and works with some of the world’s largest companies across North America and…
