About The Role

We're looking for a Full Stack Developer Intern to build and improve product features across frontend, backend, and integrations. You'll work closely with product, design, and engineering teammates on applications that need solid software fundamentals and practical execution speed.

What You'll Do

Build, test, and maintain product features across frontend interfaces, backend services, and APIs.

Collaborate with product managers and designers to translate requirements into reliable technical implementations.

Contribute to debugging, code quality, reviews, and continuous improvement of engineering workflows.

Use AI-assisted development tools responsibly to accelerate implementation, troubleshooting, and documentation.

Research and integrate useful services, libraries, or AI capabilities when they improve product outcomes.

What We Look For

Currently pursuing or recently completed a relevant degree, ideally from leading universities such as NUS, NTU, SUTD, and SMU. Strong candidates from other institutions will also be considered.

Strong academic performance, ideally distinction or above, alongside evidence of initiative, ownership, and high-quality execution.

Comfortable using AI tools beyond simple chat workflows to accelerate analysis, drafting, research, and execution.

High attention to detail and discipline in checking facts, requirements, and deliverables before sharing work.

Able to thrive in a fast-moving startup environment with ambiguity, rapid iteration, and cross-functional collaboration.

Solid grounding in software engineering fundamentals, including APIs, databases, version control, and web application architecture.

Comfort with modern development stacks across frontend and backend, plus strong debugging instincts.

Interest in building practical AI-enabled products or internal tools is a plus.

Why Apply

This is a front-row seat to venture building. You'll work on real startup-creation problems, learn how ideas are validated and operationalised, and build judgement across strategy, product, growth, and execution.
