Job Description

We are seeking a Senior Mobile Developer to lead the evolution of a mobile application used by a growing community of adventure travel and outdoor enthusiasts.

The application is currently in production on iOS, with Android as the immediate next milestone. It is powered by a multi-tenant Supabase/PostgreSQL backend and a Machine Learning platform that enables intelligent features within the app.

The application currently includes:

• GPS trip tracking
• Catch and activity logging
• Community social feed
• Machine Learning-powered species identification
• Interactive map-based location discovery
• Offline synchronization for users in areas with limited connectivity

We are looking for an engineer with proven experience building and publishing production mobile applications for both iOS and Android, ideally using React Native or Flutter , who can lead the transition from the existing native Swift application to a cross-platform solution.

This is a highly technical, hands-on role that requires ownership of the full development lifecycle—from solution design and implementation to production deployment, validation, and long-term stability.

• Responsibilities iOS Development
• Develop and maintain new features for the existing Swift-based iOS application.
• Work with SwiftUI, UIKit, CoreLocation, MapKit, and CoreData.
• Ensure high performance, stability, and quality for an application used daily by real users.

Machine Learning Integration

• Integrate Python-based Machine Learning models into the mobile application.
• Implement on-device inference capabilities.
• Consume ML outputs and maintain data contracts with backend services.
• Contribute to features such as species identification and recommendation systems.

Geospatial Features

• Design and enhance map-based functionality.
• Implement GPS tracking capabilities.
• Manage overlays, location-based filtering, and geospatial user experiences.
• Optimize offline functionality for users in low-connectivity environments.

Cross-Platform Migration

• Lead the migration from the native Swift application to React Native or Flutter.
• Evaluate both frameworks from a technical perspective.
• Define the migration strategy and implementation roadmap.
• Execute pilot projects and drive the migration through production release.
• API Design and Integration
• Collaborate with the Backend team to define API contracts.
