About the Role :

As a Senior Data Platform Engineer, you will play a pivotal role in building the core infrastructure that powers the future of autonomous driving at 42dot. This role is at the intersection of data engineering, machine learning, and autonomous systems—requiring both deep technical expertise and a system-level mindset. You will be responsible for setting the technical strategy and leading the development of our high-performance data platform, designed to process, manage, and serve massive-scale multimodal datasets for ML model training and validation. From building a robust lakehouse architecture for AD scene data to optimizing complex data processing pipelines, you'll work across disciplines to ensure the seamless flow of data that drives our autonomy stack forward. If you’re passionate about solving large-scale data challenges in a fast-paced, high-impact environment, this is your opportunity to shape how self-driving vehicles learn and evolve.

Responsibilities

Set technical strategy and oversee development of high scale, reliable data platform to manage, visualize and serve large-scale datasets for ML model training and validation.

Build up the data lakehouse for autonomous driving scene datasets, including the sensor data, calibration data, as well as annotation data

Drive the Autonomous Driving Data SDK development, including scene data search, datasets preparation, dataset loading, etc.

Dig into performance bottlenecks all along the data processing pipelines, from data processing latency, data search latency to Test Procedure (TP) coverage.

Bootstrap and maintain infrastructure for Data Platform components—Data Processing Pipeline, Database, Data Lakehouse and Data Serving.

Collaborate with cross-functional teams, including ML algorithm, ML application, and Cloud Infra to align ML Platforms with overall Autonomous Driving System Architecture.

Qualifications

Bachelor's degree or higher in Computer Science, Engineering, Robotics, or a similar technical field.

Minimum of 7 years of experience in Data Engineering or ML Platform roles

Expert-level proficiency in Python and solid experience in Python SDK development
