Company DescriptionAbout Grab and Our WorkplaceGrab is Southeast Asia's leading superapp. From getting your favourite meals delivered to helping you manage your finances and getting around town hassle-free, we've got your back with everything. In Grab, purpose gives us joy and habits build excellence, while harnessing the power of Technology and AI to deliver the mission of driving Southeast Asia forward by economically empowering everyone, with heart, hunger, honour, and humility.Job DescriptionGet to know our TeamThe Data Science (GrabMaps) team at Grab focuses on building map-based intelligence such as Place-of-Interest (POI) search and recommendation, data curation, travel time estimation, traffic forecasting, routing, and positioning. Our work powers various Grab services like transport allocation, logistics, and pricing. We extensively use computer vision, natural language processing (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 foster a culture where we enjoy raising the bar constantly for ourselves and others, and strongly support the freedom to explore and innovate.Duties and Responsibilitie
  • Collaborate with senior data scientists to adapt and fine-tune LLMs for map-related tasks such as:
  • POI enrichment (e.g., extracting attributes from text/images).
  • Search intent understanding and query rewriting.
  • Knowledge grounding using geo/POI databases.
  • Help design and evaluate agentic AI workflows that integrate LLMs with tools (search APIs, vector databases, map services) to automate tasks like POI validation, deduplication, and categorization.
  • Implement data pipelines for training/evaluating LLM-powered systems, including prompt evaluation, few-shot setups, and fine-tuning.
  • Contribute to prototyping retrieval-augmented generation (RAG) pipelines for map search and recommendation.
  • Perform experiments to measure model accuracy, latency, and robustness, and suggest improvements.
  • Write clean, maintainable code, contribute to shared libraries, and support deployment into production systems.
  • Stay updated with latest literature in LLMs, agent frameworks, and information retrieval, and apply relevant ideas in practical ways.
QualificationsRequirements
  • Master's or Bachelor's degree in Computer Science, Data Science, AI/ML, or a related field
  • Hands-on experience with deep learning (PyTorch/TensorFlow) and NLP/LLM frameworks (e.g., HuggingFace, LangChain, LlamaIndex).
  • Strong programming skills in Python; experience with Spark/SQL is a plus.
  • Familiarity with prompt engineering, fine-tuning, or adapting pre-trained LLMs for downstream tasks.
  • Solid understanding of ML fundamentals (classification, ranking, embeddings, evaluation metrics).
  • Ability to work with large-scale datasets, experience with cloud environments (AWS/GCP/Azure) is a plus
  • Good communication and collaboration skills, with an eagerness to learn and experiment.
Nice-to-Haves
  • 1-3 years of applied ML/AI experience, ideally with NLP, LLM, or agent systems.
  • Experience with retrieval-augmented generation (RAG), vector databases (Pinecone, Faiss, Milvus), or knowledge graphs.
  • Exposure to multimodal learning (text + images + geo).
  • Familiarity with ML model serving tools (TorchServe, Triton, Ray Serve).
  • Understanding of responsible AI practices such as safety, bias mitigation, and alignment.
