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$1.1B 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.

About the Role

As a Senior Software Engineer on the ScamShield team, you’ll design and build secure, high-reliability systems that operate at national scale. This role expects a blend of technical expertise, entrepreneurship and leadership skills, fostering a start-up mindset within our team.

Key Responsibilities

  • Design and develop scalable, high-quality software across the tech stack and write production-ready code.

  • Execute as a strong independent technical IC, championing best engineering practices and fostering a culture of continuous improvement.

  • Build and maintain systems that process high volumes of scam reports and messages, ensuring reliability and performance at scale.

  • Collaborate cross-functionally with multiple government agencies (e.g., Singapore Police Force, GovTech) and external partners (eg. Big Tech, banks, telcos), communicating technical tradeoffs and decisions effectively.

  • Contribute to the development and improvement of AI-powered scam detection and classification systems.

  • Identify and prioritize initiatives that maximize the security and efficiency of our products.

  • Set, measure and achieve relevant objectives, aligning team efforts with overall strategic goals.

Preferred Skills and Qualifications

  • Proficient in TypeScript, React, and AWS; experience with NestJS is a plus.

  • Knowledge in working with RDBMS (ideally PostgreSQL).

  • Experience with high-volume data processing is a strong plus — ScamShield handles large volumes of scam messages and reports daily, and the ability to design performant systems at scale is highly valued.

  • Experience with mobile app development is a plus — ScamShield includes a citizen-facing mobile app for checking and reporting scams.

  • Experience with secure software development lifecycle (SSDLC), including CI/CD processes, Git, Infrastructure as Code (IaC), and deploying applications to cloud environments.

  • Experience in startups or fast-paced environments; proven ability to succeed in dynamic settings and manage shifting priorities.

  • Experience in technical leadership, guiding software teams and setting high standards while mentoring engineers.

  • Excellent communication skills for articulating technical concepts and ideas.

  • A passion for public service, driving impactful changes, and improving how technology serves society.

Move fast with strong teams

We keep teams lean and highly empowered. You’ll work alongside experienced engineers, designers, and product builders who care deeply about craft and impact.

Grow continuously

We invest heavily in learning through hackathons, dedicated learning time, open-source contributions, and opportunities to explore new technologies and architectures.

Flexible hybrid work

We care more about outcomes than office presence, and support flexible hybrid work arrangements that work for both the team and individuals.
