Position: Senior Mapping Localization EngineerLocation: Bristol, United KingdomJob Id: 423# of Openings: 1
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 Bristol, 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.
Responsibilities
Mapping & Localization
- 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.
Point Cloud Registration & Alignment
- Improve point cloud registration pipelines for LiDAR and multi-modal datasets.
- Develop workflows for cross-session map alignment and map merging.
Sensor Fusion & Spatial Integration
- 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.
Coordinate Systems & Transformations
- Design and maintain coordinate transformation frameworks across different coordinate systems.
- Implement georeferencing and transformation validation workflows.
- Support spatial accuracy assessment and error analysis.
Camera Systems & Optimization
- Maintain and optimize camera calibration and camera pose optimization pipelines.
- Improve trajectory accuracy through joint optimization of sensor geometry and pose estimates.
Required Qualifications & Skills
- BS / MS in Computer Science, Robotics, Geomatics, Photogrammetry, Mathematics, or related field.
- 5+ years of experience in robotics, mapping, computer vision, or geospatial systems.
