Job description

What the role is:

The Land Transport Authority (LTA) is looking for passionate engineers to build the future of Singapore’s urban mobility. You will join a team dedicated to modernizing our critical national infrastructure, ensuring our traffic control systems are smarter, safer, and more resilient.

What you will be working on:

You will be at the forefront of developing the Next Generation Traffic Light Control System. This is a mission-critical project focused on optimizing traffic flow and enhancing road safety across the island.

• Production-Grade Development: Design and build modular, high-performance software components meant for real-world production systems. You will use C++ for real-time, resource-constrained control logic and Python for system automation, data processing, and integration layers. You may also be participating in web applications development if assessed to have the relevant experience.
• Rigorous Software QA: You will be responsible for the end-to-end quality of your code. This includes writing comprehensive unit tests, performing integration testing in simulated traffic environments, and ensuring that software meets the high-reliability standards required for 24/7 operations.
• Edge-to-Cloud Readiness: While current deployments are local/on-premise for security and latency, you will architect modules with a "cloud-ready" mindset (e.g., containerization-friendly, decoupled services), ensuring seamless integration for future cloud transitions.
• Critical Infrastructure Security: Implement robust security protocols to protect national infrastructure. You’ll ensure that the programming approach adhere to "Security by Design" principles.
• Continuous Learning: You will constantly explore new technologies, system architectures, and security practices. You’ll collaborate with diverse teams across the government to integrate cross-agency innovations.

What we are looking for:

We value strong engineering fundamentals and a "production-first" mindset. We are looking for individuals (1-3 years of experience, or fresh graduates who demonstrate exceptional aptitude) who possess:

• Strong Programming Foundation in one or more of the following:

  • Proficiency in C++ for performance-critical applications, with a focus on memory safety and concurrency.

  • Proficiency in Python for building robust internal tools and system modules.

  • Proficiency in in Java for web-based applications development

• Commitment to Quality (QA): Experience with, or a strong understanding of, automated testing frameworks, CI/CD pipelines, and debugging tools. You believe that code isn't "done" until it is thoroughly tested and documented.

• Engineering Excellence: A proven ability to build high-quality, secure, and maintainable software. You should be comfortable working within Linux-based environments and maintaining high standards in version control. Analytical Thinking: The ability to think clearly about abstract problems. You should have strong debugging skills—whether it's tracing a race condition in C++ or validating a logic flow in Python.

• Collaborative Mindset: Effective communication is key. You will work closely with fellow engineers, policy officers, UX designers, cybersecurity specialists, and various partner agencies.

• Proactive Initiative: You drive improvements in reliability and security autonomously. You take pride in ensuring that the software governing our roads is failsafe.

• Public Service Spirit: You care deeply about the public good and understand the responsibility of working on critical national infrastructure that impacts millions of lives daily

• As part of the shortlisting process for the role, you may be required to complete a medical declaration and / or undergo further assessment.
