Job Description

Get to Know the Team

The Data Science (GrabMaps) team at Grab focuses on building map-based intelligence such as POI search and recommendation, data curation, ETA, traffic forecasting, routing, and positioning. Our work powers multiple Grab services like transport allocation, logistics, and pricing. We use computer vision, NLP, and information retrieval along with conventional machine learning methods on a variety of signals including images, videos, text, sensor readings, and GPS probes to understand places and road networks. We also help develop scalable models through deep research to delight our customers with intelligent products. We foster a culture that supports the freedom to explore and innovate.
