As the Global Software Center of Hyundai Motor Group, 42dot pioneers the future of mobility by advancing the development of software-defined vehicles.\nWe develop safety-first, user-centric software-defined vehicle technologies that deliver the latest performance through continuous updates like smartphones. By advancing software and AI technology, 42dot envisions a world where everything is connected and moves autonomously through a self-managing urban transportation operating system.\nAbout the Role\nML-first does not mean ML-only: every model this team ships depends on a vehicle that knows precisely where its sensors are, where it is in the world, and how confident it can be in both. This role owns that foundation, building the calibration, mapping, and localization stack that every perception and planning model is built on top of, across a multi-vehicle-class fleet spanning passenger vehicles, robotaxis, buses, and trucks.\nFounding Team Opportunity\nMost autonomy programs set their calibration and localization architecture years ago and are now stuck maintaining it. This team is establishing its framework now, and an early hire will help shape:\nSensor calibration methodology and tooling, both online and offline\n\nMapping strategy, representation, and drift-detection pipelines\n\nLocalization architecture and the technical roadmap as the fleet scales\n\nResponsibilities\nDesign and implement sensor calibration systems (camera, LiDAR, radar, IMU) for factory and in-field use\n\nBuild and maintain mapping pipelines, including map creation, versioning, and drift detection\n\nDevelop and improve localization algorithms, including sensor fusion, odometry, and SLAM\n\nDefine accuracy, latency, and reliability requirements for outputs consumed by downstream teams\n\nBuild tooling to validate calibration and localization quality at fleet scale\n\nDiagnose and resolve calibration and localization failures from on-road and simulation testing\n\nQualifications\nA demonstrated ability to take difficult technical problems from ambiguity to successful deployment\n\nBachelor's, Master's, or PhD in Computer Science, Robotics, EE, Mathematics, or related field\n\n5+ years of experience in sensor calibration, SLAM, mapping, localization, or multi-sensor fusion\n\nStrong grasp of estimation theory, including Kalman filters, factor graphs, or optimization-based fusion\n\nStrong software engineering skills in C++ and/or Python, with a track record of leading projects from concept through deployment\n\nPreferred Qualifications\nAutonomous driving or robotics background across multiple vehicle classes\n\nExperience with HD map creation and maintenance pipelines at scale\n\nExperience with LiDAR, camera, or radar extrinsic calibration in production vehicles\n\nFamiliarity with functional safety requirements such as ISO 26262\n\nInterview Process\nApplication Review - Coding Test - 1st interview - 2nd interview - Offer Negotiation - Hiring\n\nThe screening procedures may vary depending on the position, schedule, or other circumstances.\nYou will be individually notified of the screening schedule and results via the email address provided in your application.\n\nCompensation\n$200,000 - $300,000\n\nAdditional Information\nIn accordance with fair hiring practices, do not include any personal information unrelated to your job qualifications (e.g., Social Security Number, family relations, marital status, age, photo, physical condition, place of birth, etc.) in your resume.\n\nAll documents must be submitted in PDF format and under 30MB in size.\n\nIf you experience issues uploading your resume, please send it along with the job posting URL to .\n\nWe strongly encourage applications from U.S. veterans and candidates eligible for employment preference under applicable laws.\n\nQualified individuals with disabilities are encouraged to apply and will receive consideration under the Americans with Disabilities Act (ADA).\n\n42dot does not accept unsolicited resumes and will not pay fees for any such submissions.
