Job description

The role is to build and own features in a consumer creator app, from design through store release, using React Native, Expo and strict TypeScript. A strong candidate has already shipped mobile apps that real people open daily, has good taste for smooth and reliable interfaces, and is comfortable moving quickly on a small team at an early stage company.

How it fits the AI era

AI tools can speed up writing screens, tests and boilerplate, so a mobile engineer can ship more in less time. The app also includes AI avatar video features, which means part of the work is fitting AI output into a polished experience. Judgment about what feels good to use, what is reliable, and what creators actually need stays human.

How it builds AI experience

Working on the AI avatar video features in a creator app would give hands‑on experience putting generative AI in front of everyday users, including handling slow or imperfect results in the interface. Someone preparing could build a small Expo app that calls a video or language model and shows progress and errors well. Learning how TikTok Shop and creator tools work would also help, since the company's AI product centers on that world.
