Product Engineer - Mandarin

We are looking for a Product Engineer with 2+ years of experience to join our fast-moving consumer social startup. You should be a product-centric, AI-native engineer who cares deeply about user experience, moves fast, and uses AI as a core part of how you build.

You will be a key player in shipping new product features for our AI-powered platform where users create and play interactive mini-apps and games — think TikTok, but every piece of content is a playable experience.

What will you be doing?

• Build and ship product features end-to-end, with a focus on new feature development across our Next.js and Python stack
• Debug and fix production issues quickly, with strong judgment around user impact and prioritization
• Partner closely with Product to turn ideas into shipped experiences and contribute to product direction and UX decisions
• Use AI aggressively in day-to-day development, debugging, prototyping, and iteration — 90%+ AI-assisted coding is the norm here
• Move quickly across the full stack to improve product quality, speed, and usability
