This is an exciting opportunity to join a current consumer technology venture as a founding mobile engineer, building an AI-powered app for pet parents from day one.
Our client is looking for a Senior Mobile App Developer to own the architecture, development and performance of its flagship consumer mobile app. You'll turn complex AI models into an intuitive, ultra-responsive app experience.

This role will suit someone who enjoys ownership, cares deeply about performance and user experience, and wants to build a product from the ground up.

Architecting, building and maintaining a scalable, high-performance mobile app using React Native, Flutter, Swift or Kotlin.
Connecting real-time AI endpoints, computer vision pipelines and voice models via REST/GraphQL APIs and WebSockets.
