[LTA-TRO] SOFTWARE ENGINEER – TRAFFIC LIGHT MGMT & SENSORS

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.
