Grabbers in the Security team

Arbie Asug

Senior Security Engineer

Accept challenges and continue to build up your skills and knowledge in response to the fast-paced changing world of technology, and that's how you can succeed at Grab.

Farrah Harriet Ratnaike

Head of Risk Strategy & Operations, GrabFin

The team is made up of tenacious individuals who never take 'impossible' for an answer. We will chisel away at a problem bit by bit, and sometimes we will tear down the house complete, but we will never walk away from solving some of the biggest challenges that could compromise our users' trust and safety.

Puneet Gambhir

Head of Risk (TIS)

Integrity is a fascinating field to be in. Saving a life by preventing a road accident, blocking an Account Takeover attempt by a fraudster, or outsmarting the scrupulous drivers to deny them fake bookings; all of these are challenging and interesting problems to solve! Though we extensively leverage data, algorithms and tech to do so, it is equally important to understand the ground realities and human psychology of the users and fraudsters to drive results.

Rangsiman Sirichawarit

Platform Safety Assistant Manager, Thailand

In the Platform, Safety and Quality team, we support the safety operations in Thailand for Grab. Individually, we might have our own projects, but we always support each other in terms of sharing ideas, insights or even the workload. There’s a real open atmosphere for sharing ideas, not just within our team but across the business. From junior Grabbers to senior and management level, all opinions by everyone are valued, so you never really feel any hierarchy. And I think this adds to what we do and how we do it.
