About Us: The product combines mobile-first experiences, AI/ML-driven insights, and thoughtfully designed user journeys to deliver meaningful, real-world impact at scale.

The team focuses on shipping high-quality consumer products with strong engineering fundamentals, scalability, and privacy-first design.

Responsibility:

• Build and own the native Android application using Kotlin
• Implement on-device ML features including wake word detection and voice activity detection for privacy-first audio processing
• Develop real-time video calling with AI-generated memory overlays
• Create robust media ingestion pipelines for photos/videos with WorkManager background processing
• Build offline-first architecture with reliable cloud sync (Cloudflare R2, TUS resumable uploads)
• Optimize performance for infinite scroll experiences with video preloading
• Integrate Camera2 API, MediaStore, and native audio/video capabilities
• Collaborate directly with the founder and mobile lead on architecture decisions

Requirements:

• 5+ years of native Android development with Kotlin and/or Flutter
• Experience building custom native modules (Kotlin/Java bridging)
• On-device ML implementation (TensorFlow Lite, ONNX, or ExecuTorch)
• Real-time communication experience (WebRTC, Agora, or similar)
• Background processing expertise (WorkManager, Foreground Services)
• Offline-first and local database experience (Room, SQLite)
• Excellent English communication skills
