What you will be working on

We are seeking a capable Full Stack Developer to join our development team and build secure, scalable and resilient cloud-based digital solutions. The role covers traditional software development, low-code/no-code delivery, cloud services setup for leveraging cloud native solutions, system integration and application Security Operations. The successful candidate will contribute to the development of digital solutions that provide a central platform for engineering project information sharing and collaboration, enabling seamless coordination among LTA, contractors, and government agencies across rail and road infrastructure projects.

Software Development & AI Implementation

Develop, enhance and maintain scalable, resilient and secure low-code/no-code platforms using modern programming languages and frameworks. Design and implement responsive web, workflow and mobile solutions with intuitive user interfaces that address business and user needs. Implement AI features by integrating machine learning models, APIs, and cloud AI services into production applications built on both traditional and low-code/no-code platforms. Write clean, maintainable and well-documented code in accordance with established coding standards and software engineering practices. Participate in code reviews, technical design discussions and architecture reviews, and contribute to continuous improvement of engineering practices. Develop automated tests and maintain technical documentation, configuration records and architecture decision records.

Low-Code/No-Code Development

Work with business analysts and stakeholders to translate business requirements into fit-for-purpose solutions using low-code/no-code platforms. Configure and develop workflows, forms, dashboards and business applications while ensuring maintainability, scalability, security and appropriate governance. Integrate low-code/no-code applications with external systems, databases, cloud services and APIs. Assess when to use low-code/no-code, custom development or a hybrid approach based on functional, security, performance and supportability needs. Troubleshoot application and platform issues and apply platform-agnostic development and governance best practices.

Cloud Services Setup and Deployment

Build applications leveraging cloud platforms such as AWS, Azure, or Google Cloud Platform, utilising their core & cloud-native services and AI capabilities. Develop and deploy microservices, containerised applications and serverless functions as part of enterprise system architectures. Implement cloud services’ configuration and deployment practices that promote consistency, security and repeatability across development, test and production environments. Collaborate with DevSecOps and infrastructure teams to implement CI/CD pipelines, release applications and monitor application deployment governance process.
