Who We Are

Open Government Products (OGP) operates like a startup within the government; We are a fast-paced team of engineers, designers, and product managers dedicated to public good. We autonomously identify opportunities to solve public problems using tech, rapidly prototype, and launch solutions all the way from citizen-facing apps to automating public agency operations. Embracing an open-sourced and flat hierarchy, we cut through bureaucracy to focus on real-world, user-centric innovations that drive change.

The Team

In 2024, over S$1.1B was lost to scams in Singapore. Numbers for the first half of 2025 have shaped up to be in the same range. Public awareness and education about scams is not enough, we need active efforts in preventing scams from happening in the first place.

You will be joining the ScamShield team, which builds and operates Singapore's national anti-scam platform. As Singapore's unified citizen-facing brand for anti-scam efforts, ScamShield protects citizens from scam messages, calls, and links through AI-powered detection systems, provides tools for government agencies like the Singapore Police Force to coordinate anti-scam efforts at scale, and is expanding into scam awareness and education to help citizens recognise and avoid scams before they happen.
