Software Engineer / Senior Software Engineer, Anti-Scam Products

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.

About the Role

As a Software Engineer on the SGC team, you'll design and build secure, high-reliability systems that operate at national scale.

You'll work across the stack — from frontend experiences to backend services and cloud infrastructure — helping shape the architecture, engineering standards, and long-term technical direction of critical public platforms.

This role is ideal for engineers who enjoy high ownership, solving complex technical problems, and building products that have meaningful real-world impact.

As an Engineer, you will:

• Build and ship high-quality product features end-to-end.
• Design scalable services and maintainable frontend/backend systems.
• Collaborate closely with product managers, designers, and engineers to deliver impactful solutions.
• Contribute to engineering best practices, testing, observability, and system reliability.
• Take ownership of technical projects and continuously improve the developer and user experience.

As a Senior Engineer, you will additionally:

• Drive technical architecture and engineering strategy for critical systems.
• Lead complex initiatives spanning multiple services or stakeholders.
• Improve platform security, resilience, scalability, and operational excellence.
• Mentor and grow other engineers through technical leadership and code reviews.
• Identify high-leverage opportunities and help shape product and technical direction.

What We're Looking For

We value engineers who:

• Care deeply about building reliable, secure, and user-centric software.
• Thrive in fast-moving, high-ownership environments.
• Balance pragmatism with strong engineering fundamentals.
• Communicate clearly and collaborate effectively across disciplines.
• Are motivated by meaningful public impact.

Technical skills and experience

• Strong software engineering fundamentals and experience building production systems.
• Experience with modern web and cloud technologies such as:
• TypeScript
• React
• Node.js
• AWS / cloud-native infrastructure
• API-first system design
• Familiarity with secure software development practices, including:
• CI/CD pipelines
• Infrastructure as Code (IaC)
• Git-based workflows
• Cloud deployments and observability
• Experience operating systems in production and debugging real-world reliability issues.

Additional qualities for Senior Engineers

• Experience leading large or technically complex projects with minimal supervision.
• Ability to make sound architectural and technical tradeoff decisions.
• Track record of mentoring engineers and raising engineering quality within teams.
• Strong stakeholder management and cross-functional collaboration skills.

Why Join OGP

Work on problems that matter

Your work will directly impact how millions of Singaporeans interact with government services and stay protected from scams and digital threats.

Build with real ownership

Engineers at OGP own products end-to-end — from ideation and architecture to deployment and operations. You'll have significant influence over technical decisions and product direction.

Solve meaningful technical challenges

Our systems require strong engineering across security, reliability, scalability, identity, messaging infrastructure, and developer tooling.

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.

Projects OGP has worked on include:

ScamShield — ScamShield helps users detect, filter, and report scam calls and messages using AI-powered detection systems and reporting workflows that support law enforcement investigations.

RedeemSG — A nationwide digital voucher platform used for government disbursement and benefits programmes.

data.gov.sg — Singapore Government's open data platform providing public datasets, APIs, visualisations, and data-driven insights.

ActiveSG - A platform for the public to book sports facilities, join fitness programmes, and access gym and swimming facilities.
