Calibration, Mapping & Localization Engineer

42dot • San Francisco, CA

11h • $150,000 - $205,000

About The Position

42dot is a mobility AI company and the Global Software Center of Hyundai Motor Group, developing software-defined vehicle technologies through software and AI. The Calibration, Mapping & Localization Engineer will build the calibration, mapping, and localization foundation used by perception and planning models across a multi-vehicle-class fleet that includes passenger vehicles, robotaxis, buses, and trucks.

As an early member of a founding team, this engineer will help establish sensor calibration methodology and tooling for online and offline use, mapping strategy and representation, drift-detection pipelines, and localization architecture and technical roadmaps as the fleet scales. The role covers factory and in-field systems, as well as validation and diagnosis using on-road and simulation testing.

Requirements

• Bachelor's or Master's degree in Computer Science, Robotics, Electrical Engineering, Mathematics, or a related field.
• 2–4 years of experience in sensor calibration, SLAM, mapping, localization, or multi-sensor fusion.
• Working knowledge of estimation theory, including Kalman filters, factor graphs, or optimization-based fusion.
• Solid software engineering skills in C++ and/or Python.
• Experience contributing to production-grade robotics systems.
• Ability to work through difficult technical problems methodically, with growing independence.

Nice To Haves

• Exposure to autonomous driving or robotics across multiple vehicle classes.
• Exposure to HD map creation and maintenance pipelines.
• Experience with LiDAR, camera, or radar extrinsic calibration.
• Familiarity with functional safety requirements such as ISO 26262.

Responsibilities

• Design and implement sensor calibration systems for cameras, LiDAR, radar, and IMUs for factory and in-field use.
• Build and maintain mapping pipelines, including map creation, versioning, and drift detection.
• Develop and improve localization algorithms, including sensor fusion, odometry, and SLAM.
• Define accuracy, latency, and reliability requirements for outputs consumed by downstream teams.
• Build tooling to validate calibration and localization quality at fleet scale.
• Diagnose and resolve calibration and localization failures found in on-road and simulation testing.
• Help shape the team's calibration methodology and tooling, mapping strategy and representation, drift-detection pipelines, and localization architecture and technical roadmap.
