Senior Mobile Engineer
We are looking for a Senior Mobile Engineer to help turn a validated AI consumer app into a production-ready product for iOS and Android. You will take ownership of the mobile delivery layer, connecting an existing frontend direction with the backend, monetization, and release workflows needed for a real public launch.
This is a hands-on contract role for someone comfortable shipping quickly, making practical product decisions, and working across mobile UX, camera-based user flows, and AI-powered product features.
Responsibilities
- Own the end-to-end mobile implementation in Flutter or React Native, from feature integration to release readiness.
- Design and implement a guest-first experience where users can complete an initial scan before sign-up is required.
- Integrate Firebase to support user profiles, scan history, and compliant account deletion flows.
- Implement the monetization flow with RevenueCat, including free scan access and gated premium report details.
- Build and optimize marketplace and affiliate-link flows, including reliable deep-link behavior into external store apps.
- Improve the image pipeline by compressing photos before AI requests and partnering on prompt design to improve material classification accuracy.
- Prepare the app for testable beta release across App Store and Google Play.
Requirements
- Strong experience shipping production mobile apps with Flutter or React Native.
- Hands-on experience with Firebase, mobile authentication, and persistent user data flows.
- Experience implementing subscriptions, paywalls, or in-app monetization with tools such as RevenueCat.
- Good understanding of deep linking, external commerce flows, and mobile UX for conversion-oriented products.
- Comfort working with AI-powered features, prompt iteration, and practical optimization constraints such as image size, latency, and cost.
- Ability to operate independently in a fast-moving product environment and deliver working software on a tight timeline.
