Job description

**Co-Founder & Full-Stack Mobile Developer**

**Compensation:** $0 salary (significant equity / co-founder stake)

**Type:** Co-founder position – high risk, high responsibility, high potential reward

We are looking for a technical co-founder who will build and own the complete mobile product.

You will:

• Build iOS and Android apps from scratch (working, production-quality apps)
• Create the backend and APIs
• Set up and manage AWS (databases, storage, authentication, hosting…)
• Handle app store submissions (both App Store and Play Store)
• Make technical decisions and keep improving the product after launch
• Fix issues quickly when things break

Must have real experience with:

• **iOS** — Swift + SwiftUI (or strong UIKit experience)
• **Android** — Kotlin (preferred) + Jetpack Compose (or modern views)
• Shipped at least one real app to **both** stores
• AWS (used several services in real projects: e.g. Lambda, DynamoDB, S3, Cognito, API Gateway…)
• Building and launching mobile apps end-to-end

Big plus if you also know:

• Clean architecture & testing
• CI/CD for mobile (Fastlane, GitHub Actions…)
• Basic cost‑aware AWS setup
• Push notifications, authentication, basic analytics

We’re looking for someone who:

• Wants to be a real co-founder (not just a hired developer)
• Can work without salary for a longer period
• Is okay building alone in the beginning
• Cares about actually shipping a working product

What you get:

• Large co-founder equity (to be discussed seriously)
• Full ownership of the technical side
• Freedom to shape how the product is built
• Chance to build something big from zero

How to apply

Just send:

• Links to 1–2 apps you published (App Store / Play Store)
• Short note about your mobile + AWS experience
• One sentence about what kind of equity/co‑founder deal you expect
