## Job description

## WE ARE LOOKING FOR THE BEST

## ABOUT US

42dot is a mobility AI company committed to solving mobility challenges with software and AI. As the Global Software Center of Hyundai Motor Group, 42dot pioneers the future of mobility by advancing the development of software-defined vehicles.

We 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.

## ABOUT THE ROLE

We are building next-generation vehicle modeling and data technology at 42dot by combining physics-based models, machine learning, simulation, and large-scale vehicle data.

As a Machine Learning & Data Engineer, Vehicle Modeling, you will develop ML and data infrastructure that improves vehicle models and supports broader vehicle intelligence and autonomous driving development. You will work across vehicle telemetry, simulation, test data, fleet data, and cloud platforms to build scalable systems for model development, evaluation, and continuous improvement.

A core focus of this role is using real-world vehicle data to identify model performance gaps and improve models through calibration, parameter estimation, machine learning, and hybrid physics-and-data approaches. You may develop ML models that complement physics-based models, estimate model parameters under different vehicle states and operating conditions, or improve predictions where physical models alone are insufficient.

You will also help build the data and cloud infrastructure needed to ingest, clean, organize, process, and evaluate large-scale vehicle datasets, supporting modeling, simulation, vehicle intelligence, and autonomous driving workflows. This role sits at the intersection of machine learning, data engineering, physical system modeling, simulation, and vehicle software.

## Responsibilities

- Develop machine learning and hybrid physics-data approaches to improve vehicle and component model accuracy.
- Develop methods for model calibration, parameter estimation, adaptive modeling, and data-driven model improvement across different vehicle states and operating conditions.
- Build scalable workflows for comparing model predictions with test, simulation, and real-world vehicle data and identifying opportunities for model improvement.
- Build pipelines for ingesting, cleaning, synchronizing, transforming, storing, and accessing large-scale vehicle telemetry and time-series data.
- Develop cloud-based infrastructure for data processing, model training, simulation, evaluation, and validation.
- Build tools and workflows for dataset management, model evaluation, experiment tracking, and reproducible model development.
- Support data processing, model evaluation, and analysis workflows used by vehicle intelligence

Interview Process

- Application Review - Coding Test - 1st interview - 2nd interview - Offer Negotiation - Hiring
- The screening procedures may vary depending on the position, schedule, or other circumstances.

You will be individually notified of the screening schedule and results via the email address provided in your application.
