Senior Machine Learning Engineer (Simulation)

Get to know the Team

The Fulfilment Tech family is one of the pillars allowing Grab to out-serve our consumers and partners in different businesses and marketplaces across Southeast Asia. We are working on high-throughput real-time distributed systems that use machine-learning techniques to solve hundreds of millions of requests per day. Our mission is to offer the best products and experiences to our driver partners to increase the adoption and engagement of our services. Improve driver partner opportunities and efficiency to fulfil consumer orders without fail rain or shine. And to create efficient marketplaces by determining a price that is both sustainable and loved by our partners and consumers.

Grab is Southeast Asias leading super-app. We provide everyday services such as deliveries mobility financial services enterprise services and others to millions of users across the region. At the fulfilment machine engineering team we are trying to solve challenging problems in the marketplace that involve dynamic pricing supply and demand management. We are looking for senior machine learning engineers to join the team to help us make that vision a reality by developing and refining cutting-edge reinforcement learning models and simulation platforms.

Get to know the Role

Reporting into the Senior Engineering Manager and based in Grab Singapore One North office this is a hands-on role involving building large-scale simulation platforms. You will build a digital twin of Grabs marketplace that consists of tens of thousands of consumers drivers and merchants. Furthermore you will develop reinforcement learning optimization and control models to solve business problems inside Grabs marketplace and deploy them at scale.

The Critical Tasks You Will Perform

• Architect and develop our simulation platform to simulate the response from the marketplace that involves different types of services that Grab is providing
• Work with data scientists and engineers to design simulation flow that would support their Platform Policy designs and optimisations
• Collaborate with data scientists and engineers to design simulation SDKs to improve the user experience of the simulation platform
• Work with Data Scientists to integrate and build feedback loops to run policy search using the simulation platform
• Design and scale the simulation platform to run hundreds and thousands of simulations per day
• Contribute to service capacity and demand planning software performance analysis costing tuning and optimization.
• Participate in code and design reviews to maintain our high development standards.

Qualifications :

What Essential Skills You Will Need

To perform the tasks above you will need:

• At least 2 years building production machine learning systems that serve live traffic and require you to handle model deployment monitoring and maintenance
• At least 2 years developing large-scale simulation environments modelling complex systems with multiple working entities (e.g. marketplaces logistics networks or agent-based systems)
• Professional-level coding in Scala and Python to build the simulation platform core and ML model pipelines
• Professional-level coding in Golang to develop microservices that handle real-time marketplace data streams
• Experience with functional programming frameworks (such as Cats Effect or similar) to build concurrent non-blocking systems that handle high-throughput data processing
• Experience with at least one ML framework (TensorFlow or PyTorch) to implement reinforcement learning models for marketplace optimization
• Experience with distributed data processing frameworks (such as Spark or Ray) to grow simulations across compute clusters and process large-scale training data
