We are building a next-generation product at the intersection of music, artificial intelligence, and human science — combining biometric data, AI models, and audio experiences to create something fundamentally new.

Over the past 18 months, we’ve been quietly validating the vision, assembling a world-class advisory board (ex-Google, Spotify, Pandora, along with multiple Medical PhDs).

Now, we’re entering the next phase — and looking for founding engineers who will define the technical backbone of the company.

Why This Role is Different

This is not a typical startup role.

• You won’t inherit legacy systems — you will build from scratch
• You won’t follow processes — you will define them
• You won’t be “just an engineer” — you will act as a product builder and technical owner

This is a 0→1 opportunity with real momentum behind it.

What You’ll Be Working On

• Designing and building a mobile-first product ecosystem (iOS + cross-platform)
• Developing real-time, data-driven music experiences powered by AI and biometric inputs
• Creating seamless interaction between:
  • mobile applications
  • native iOS components (including Apple Watch integration)
  • backend AI/data systems

You will work directly with product, medical, and industry experts to translate complex signals into intuitive user experiences.

Your Responsibilities

• Own mobile architecture — define structure, scalability, and best practices from day one
• Build and ship fast — from prototype to production-ready features
• Work across layers — React Native + native iOS (Swift) + API integrations
• Design high-performance UI — real-time interactions, async data flows, smooth UX
• Integrate native modules — especially for device-level features and wearable interactions
• Collaborate with R&D — bridge engineering with AI, audio, and health-tech domains

Tech Stack

• Mobile / Frontend: React Native (TypeScript), Swift (iOS)
• Backend / Cloud: AWS, PostgreSQL (RDS)
• Nice to have:
  • Audio processing
  • AI integrations
  • Health / biometric data

What We’re Looking For

• 3+ years of experience in mobile or frontend development (production apps)
• Strong expertise in React Native (JavaScript / TypeScript)
• Solid experience with native iOS development (Swift)
• Experience integrating native modules and SDKs
• Understanding of mobile architecture, state management, and scalable code design
• Experience building real-time, high-performance UI
• Ability to debug across JS + native layers + mobile environments
• Experience working with external APIs
