Senior Mobile Engineer (React Native)

About Us

We are building a new kind of music-learning and music-play experience — inspired by products like Duolingo, but focused on music foundations: rhythm, pitch, notation, ear training, creative expression, and joyful musical play.

We believe music is best learned through doing, hearing, and playing, not memorizing theory. Our experiences are short, interactive, game-based, and grounded in modern music pedagogy and strong game design.

At us, music is not just content — it is gameplay.

Role Objective

• Architect, build, and launch our mobile app with a focus on delivering world-class gamified learning.
• Leverage AI tools to accelerate development, automate repetitive tasks, and improve collaboration and velocity.

Key Responsibilities

1) App Development

• Take part in development of the mobile app (starting iOS-first).
• Implement the new music course and mini-games within the app
• Write clean, maintainable, and testable code using modern best practices.

2) Feature Implementation

• Build beautiful UI components and smooth animations
• Integrate backend APIs for auth, progress tracking, user data and lesson content
• Implement analytics and event tracking (e.g., Firebase, Mixpanel).
• Integrate in-app monetization flows (subscriptions, ads).

3) Performance & Quality

• Optimize app responsiveness, loading time, UI fluidity, and crash-free sessions
• Ensure smooth UX even on mid-range devices.
• Contribute to CI/CD workflows, crash logging, and release automation.

4) AI-Augmented Engineering

• Use AI tools to:

1. Scaffold components, animations, or scene/state flow faster.
2. Generate documentation, error handling templates, or test cases.

• Explore co-pilot tools (e.g. Copilot, Claude, Codex) in daily workflow.

5) Collaboration & Ownership

• Work closely with the Tech Lead and other team members to align architecture and scaling strategy.
• Partner with Product and Design to deliver a mobile experience that feels magical.
• Take long-term ownership of mobile architecture and evolution roadmap.
