Product Builder Intern (Product Engineering)

Our Journey The Shop. Back Group is Asia-Pacific's leading shopping and rewards platform, trusted by over 20 million active members across 13 markets, including Germany and the United States. Driven by the vision to make every day more rewarding, Shop. Back saves members money and time with more ways to earn and more to do with what they earn, and empowers merchants and brand partners to effectively engage its members.

Founded in Singapore in 2014, Shop. Back now powers over US$5.5 billion in annual sales and half a million transactions a day for more than 20,000 online and in-store partners. The Opportunity Shop. Back serves 45M+ shoppers across Asia with cashback, deals and discovery. We are now building the layer on top: Artificial Intelligence (AI)-native shopping experiences that personalise, guide and delight at scale.

This is not your average internship. You will not be handed cosmetic tasks and told to stay in your lane. You will be given real consumer surfaces, an AI-native toolkit, and the expectation that you ship something people use. This role is technical. Alongside consumer surfaces you will work on the AI infrastructure the design team runs on: the machine-readable layers that let coding agents build on our design system, the evaluation harnesses that score what those agents produce, and the internal tools the rest of the team depends on.

Expect more frontend and tool design than traditional design work. We are looking for someone who sits between product thinking and building. Not an intern who only makes things look right. Not an intern who only writes documents. A builder in training who does both, and who is energised rather than paralysed by an open brief.

You will work alongside a team that has moved past "add AI to the product" and builds AI-first from the ground up, collaborating with product and business teams across 13 markets.
