Senior Data Scientist (GrabFin)

About Grab and Our Workplace

Grab 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.

Get to Know the Team

Financial Services (FS) brings together FinTech and Banking businesses across 6 countries in Southeast Asia, covering Lending, Payments, and Insurance. You'll join a team building financial services for drivers, consumers, and merchants within the Grab ecosystem. The team combines market insights with data science and engineering to develop products that fit user needs. You'll work in a flat structure with ownership over your models and solutions, focusing on both batch and real-time data science applications.

Get to Know the Role

You'll build and deploy production-grade machine learning systems for FS Lending products serving drivers, passengers, and merchants. You'll develop predictive models using machine learning and deep learning techniques, create data pipelines, and validate model performance on real-world datasets. You'll work with product managers, engineers, and data scientists to translate business requirements into ML solutions.

You'll report into the Principal Data Scientist and work onsite in Grab One North Singapore office.

The Critical Tasks You Will Perform

You will:

• Build and deploy scalable ML models using Python, Spark, and cloud-native tools to predict lending outcomes and customer behaviour.
• Develop data pipelines and feature stores to support model training and inference, ensuring data flows correctly from source to production.
• Engineer predictive features from internal data assets and identify external data sources to incorporate into model development.
• Validate model performance on real-world datasets and lead model refresh cycles when you detect performance drifts or gaps.
• Present model findings to senior leadership, explaining risk trade-offs and quantifying business impact in clear terms.
• Translate model insights into strategic recommendations for policy changes, pricing adjustments, or customer targeting strategies.

What Essential Skills You will Need

• At least 3 years of experience building ML models in production environments — You'll deploy models that directly impact lending decisions, requiring ability to move models from experimentation to production.
• Experience with multi-agent systems using frameworks like LangGraph, CrewAI, or ADK — You'll implement agent-based systems for complex decision-making workflows using patterns such as ReAct, self-reflection, or hierarchical delegation.
• Python programming for ML development — You'll write and maintain code for model development, pipeline automation, and deployment. You can demonstrate this through prior work on ML systems.
• Experience with distributed data processing (Spark, SQL) — You'll build pipelines handling large-scale financial data across multiple markets, requiring ability to process data across distributed systems.
• Proficiency with ML/ DL libraries (scikit-learn, XGBoost, TensorFlow or PyTorch) — You'll select and apply appropriate algorithms for credit risk modelling and customer prediction tasks.
• Experience with feature engineering and model evaluation metrics — You'll create features from raw transaction and behavioral data, and select metrics that properly measure model performance for financial applications.
• You can explain model behavior to non-technical stakeholders — You'll regularly present to product managers and leadership, requiring you to communicate technical concepts in accessible language and connect model outputs to business outcomes.
