About the Role
We are seeking a Principal Machine Learning Engineer to join our Fulfilment team at Grab. This strategic role focuses on optimizing fulfillment strategy and modeling driver behavior to improve pricing, dispatch, and supply management policies across our Southeast Asian marketplaces.
Key Responsibilities
- →Lead development in reinforcement learning, behavioral prediction, and simulation-based optimization techniques
- →Build interpretable, adaptable multi-agent RL systems that handle multiple objectives and disruptions
- →Develop high-fidelity models that simulate marketplace operations
- →Design feedback loops that adapt to driver behavior over time and across geographies
- →Collaborate with platform and experimentation teams to run real-world validations
- →Build tooling and simulations for counterfactual analysis and platform design decisions
- →Guide data scientists as a technical lead in these efforts
- →Integrate optimization models into real-time production systems
Requirements
- ✓Advanced ML/DL models expertise to enhance performance and improve generalization and efficiency
- ✓Experience developing unified RL architectures that coordinate multiple levers with differing objectives
- ✓Ability to build multi-agent or hierarchical RL frameworks for optimizing pricing, dispatching, and repositioning decisions
- ✓Knowledge of scalable representations of marketplace state incorporating supply-demand signals, elasticity, traffic, weather, and driver intent
- ✓Strong background in developing robust, interpretable models to capture driver decision-making
- ✓Experience with feedback loop design that adapts to driver behavior
- ✓Proficiency in collaborating with cross-functional teams for real-world validations
- ✓Technical leadership experience guiding data scientists
