Job description

Who We Are

Open Government Products (OGP) is an experimental technology team within the Singapore Government. We build technology for public good — creating products that directly improve the lives of millions of people in Singapore. We operate with the speed and autonomy of a startup, while working on problems with national scale and impact. Our teams are made up of engineers, designers, product managers, and operators who identify real public problems, rapidly prototype solutions, and bring them into production. Our products span citizen-facing services and critical internal government systems. We work in small, empowered teams with high ownership, minimal bureaucracy, and a strong open-source and engineering culture.

The Team

In 2024, over S$1.1 billion was lost to scams in Singapore. Victims range from elderly folks losing their life savings to young professionals deceived through increasingly sophisticated government impersonation scams. Public education alone is no longer enough. Preventing scams at scale requires trusted infrastructure, secure communication systems, and technology that can stay ahead of rapidly evolving threats. The Secure Government Communications (SGC) team builds systems that help Singaporeans distinguish legitimate government communications from scams.

Our Products Include

• Postman - a secure messaging platform that enables government agencies to communicate officially and safely with the public
• Gov.sg Sender ID - Singapore’s unified trusted sender identity for government SMS communications

These systems sit at the intersection of security, reliability, identity, and public trust — serving millions of citizens and supporting critical national communications infrastructure.
