This role is suitable for engineers with 1-3 years of experience; fresh graduates with strong fundamentals, internship experience, or relevant project work may also be considered.

Key Responsibilities

• Deliver functional, tested, secure, and scalable software features based on the product backlog and agreed sprint priorities.
• Work in cross-functional Agile teams and contribute to sprint planning, backlog refinement, development, reviews, retrospectives, and continuous improvement.
• Collaborate with QA engineers, Product Designers, DevOps engineers, Business Analysts, Product Owners, and stakeholders to ensure solutions meet both technical and user requirements.
• Clarify requirements where required and translate business or user needs into technical specifications, implementation tasks, and acceptance considerations.
• Develop front-end applications, backend services, APIs, and software modules using the project’s approved technology stack.
• Support development for Proof of Concept (POC) and/or Initial Operations Capability (IOC) initiatives, enabling safe experimentation and incremental delivery.
• Write and maintain unit and integration tests to support automated testing, quality gates, and continuous integration pipelines.
• Design, implement, and maintain CI/CD pipeline templates for automated build, testing, security scanning, and deployment in alignment with the Authority's toolchain.
• Set up, maintain, and troubleshoot development environments to support productive development, testing, and experimentation.
• Apply DevSecOps practices, Infrastructure as Code (IaC) principles, secure coding standards, and software maintenance best practices where applicable.
• Investigate, troubleshoot, and resolve software defects, technical issues, and post-deployment support matters in a timely manner.
• Participate in code reviews, technical documentation, technical evaluation, benchmarking, and quality assurance activities.
• Work with minimal supervision on assigned modules and, where required, coordinate small tasks or workstreams while contributing to team delivery and technical discussions.

Job Requirements

• Degree in Information Technology, Computer Science, Software Engineering, or a related discipline. 1-3 years of relevant software development experience is preferred; fresh graduates may be considered.
• Proficiency in one or more relevant languages or frameworks, such as TypeScript with Angular, React, or Next.js; C#; Java; or other languages depending on project needs.
• Familiarity with one or more database technologies, such as MSSQL, PostgreSQL, or Oracle.
• Good understanding of SDLC practices, object-oriented programming, RESTful API design, microservices concepts, software maintenance, and secure coding practices.
• Familiarity with Agile and Scrum practices, with the ability to work in sprint-based delivery environments.
• Familiarity with DevOps principles, CI/CD pipelines, automated testing, code quality practices, and version control tools such as Git and GitHub or equivalent platforms.
• Knowledge of containerisation and orchestration technologies such as Docker and Kubernetes will be advantageous. Exposure to cloud environments, Infrastructure as Code, or DevSecOps toolchains will be an added advantage.
• Able to apply industry best practices in quality assurance, technical evaluation, and benchmarking, and adapt approaches based on project requirements.
• Strong analytical and problem-solving skills, with the ability to investigate issues, evaluate options, and propose practical technical solutions.
• Able to communicate clearly and collaborate effectively within cross-functional teams and with stakeholders.
• Keen to learn, adaptable, responsible, and comfortable working in a mission-driven environment where quality, security, and impact matter.
