About the Job

Requirements

  • A master's degree in computer science, electrical engineering, mechanical engineering, robotics, or a related field with at least 3 years of experience, or a PhD.
  • Understanding of computer vision, robotics, SLAM, localization, or 3D geometry.
  • Experience developing and implementing algorithms in C++.
  • Experience analyzing data and validating algorithms using Python.
  • Understanding of linear algebra, multi-view geometry, probability, and nonlinear optimization.
  • Development experience in a Linux environment.

Responsibilities

  • Develop offline SLAM and localization algorithms using sensor data from cameras, LiDAR, IMU, GNSS, and other sensors.
  • Develop trajectory estimation, pose optimization, and global alignment algorithms for large-scale driving data.
  • Develop multi-sensor self-calibration and calibration algorithms for cameras, LiDAR, IMU, and other sensors.
  • Improve 3D reconstruction accuracy using multi-view geometry, structure-from-motion, and bundle adjustment.
  • Research and apply neural-rendering-based 3D reconstruction technologies, including NeRF and 3D Gaussian Splatting, to the data pipeline.
  • Build and continuously improve quality assessment and validation systems for localization, calibration, and 3D geometry data.
  • Apply algorithms to large-scale data-processing pipelines and build automated data-generation and quality-improvement processes.
  • Develop technologies to improve AI training-data quality in collaboration with Perception, AI, Data Platform, and other organizations.

Desired Qualifications

  • Experience developing visual SLAM, LiDAR SLAM, visual odometry, or offline localization algorithms.
  • Experience developing multi-sensor localization, sensor fusion, and sensor self-calibration algorithms.
  • Experience developing extrinsic, intrinsic, or temporal calibration for cameras, LiDAR, or IMU.
  • Experience developing geometry-based optimization algorithms such as factor graph optimization, pose graph optimization, and bundle adjustment.
  • Experience developing structure-from-motion, multi-view stereo, point-cloud registration, or dense 3D reconstruction.
  • Experience developing neural-rendering-based 3D reconstruction technologies such as NeRF and 3D Gaussian Splatting.
  • Experience with camera- and LiDAR-based 3D geometry reconstruction and quality improvement.
  • Experience using related frameworks such as Ceres Solver, GTSAM, COLMAP, and Open3D.
  • Experience processing large-scale driving data and evaluating data quality.
  • Publication of relevant papers at conferences such as CVPR, ICCV, ECCV, ICRA, IROS, RSS, or SIGGRAPH, or contributions to open-source projects.

About the Company

42dot

Unified platform for multi-modal urban mobility

42dot.ai provides a platform called UMOS (Urban Mobility Operating System) that connects and manages multiple transportation modes—such as cars and drones—within a single system for cities, agencies, and private clients. UMOS enables efficient transportation management, demand-response services, and smart logistics by integrating data and operations across modes, powering operations through a subscription-based platform-as-a-service model. Unlike single-mode solutions, 42dot.ai offers multi-modal, city-focused orchestration that bridges public, private, and logistics needs. The company aims to transform urban mobility by helping cities run more efficiently, cut costs, and improve the experience for commuters and logistics providers.
