Ever wondered how different government agencies work together behind the scenes to power the web and mobile apps you use every day in Singapore? Much of that collaboration happens through APIs, and APEX Cloud (https://www.apex.gov.sg) is the one-stop platform that helps agencies securely connect, share data, and build digital services together. As an APEX intern, you will join the team building the APEX Gateways, Portals, CLI tools, and SDKs that make these integrations smoother, safer, and may even enable new forms of collaboration! Your work will contribute to real government applications and services used by millions of people, while giving you hands-on experience with large-scale systems, security, and developer platforms.

Learning Outcomes

- Gain hands-on experience building production-grade applications using modern web technologies such as React, Next.js, and Node.js across both frontend and backend development. - Develop practical skills in cloud infrastructure and DevOps, including AWS, Terraform, Kubernetes, and CI/CD pipelines. - Participate in the end-to-end software delivery lifecycle, from feature design and implementation to testing, deployment, and monitoring. - Work on real, high-impact government systems used by multiple agencies and millions of users nationwide. - Learn and apply API standards, authentication flows (OAuth, mTLS), and security best practices including zero-trust principles. - Contribute to live customer problem-solving, including bug fixes, feature enhancements, and solution customisation for agency needs. - Gain exposure to software architecture discussions, code reviews, and engineering best practices in a large-scale platform environment. - Experience Agile team practices such as sprint planning, stand-ups, retrospectives, and collaborative delivery. - Build technical communication and stakeholder engagement skills through demos, documentation, and cross-team discussions. - Optional exposure to product management and feature scoping for interns interested in the product or strategy track.

Prerequisites

- Proficient in at least one programming language (e.g. JavaScript, TypeScript, Java or Python). - Familiarity with the underlying frameworks used in APEX (React, Node.JS) - Basic understanding of web development concepts such as HTTP, REST APIs, and frontend/backend interactions. - Familiarity with Git and collaborative development workflows (pull requests, code reviews). - Comfortable working in a Linux or command-line environment and willing to learn new tools quickly. - Preferred but not required: Exposure to Next.JS, cloud platforms (AWS), DevOps concepts (CI/CD, Docker, Kubernetes), or infrastructure tools such as Terraform.
