Job Description

Get to Know the Team
The GrabX team, a key component of Grab's Tech Infra, builds and maintains the high-scale, reliable experimentation platform used across all of Grab's marketplaces. We empower product and engineering teams to make data-driven decisions by providing world-class tools for A/B testing, statistical analysis, and measurement of business-critical metrics.
Our mission:
* Enable fast, reliable, and scientifically sound experimentation for all product teams.
* Develop robust causal inference and statistical methodologies to measure the impact.
* Ensure the integrity, scalability, and performance of the core experimentation platform.
Get to Know the Role
You'll help shape the future of experimentation at Grab. Your primary objective will be to optimize and develop novel A/B testing methodologies, ensure metric reliability, and advance the platform's capabilities for complex experimental designs. This includes developing solutions for issues like platform contamination, sample ratio mismatch, and network effects, all within a large-scale, distributed infrastructure environment.
You will work onsite from our Petaling Jaya office.
The Critical Tasks You Will Perform
* Contribute to active Apache Flink pipeline development for CDP attribute ingestion and Scribe event processing workstreams
