Mobile Game Developer — Build a Game for a Product With 300,000+ Users

We're FUNPUNCH. We make the Rage-Bag — a portable punching bag that's sold over 300,000 units and become a genuine phenomenon in active play. Now we're building the thing that takes it to the next level: a mobile game, paired with the physical product, that uses your phone to detect your real punches and turns every session into a game you level up in. Here's the opportunity: this year alone, 300,000+ people will be onboarded into this app. Every Rage-Bag ships pointing customers straight to it. You won't be building a game and hoping people find it — you'll be building a game with a massive, built-in audience waiting on day one. THE MISSION Our app is becoming core to the product itself. It's a camera-based boxing game: the phone sees your punches, you train real moves, play game modes, climb ranks, and unlock rewards. Long-term, we're building it into a real business — subscriptions, in-app items, and a channel to promote our products to a huge engaged audience. We need someone to own this and make it world-class. WHO WE'RE LOOKING FOR This is for a proven mobile-game builder. Someone who has: - Shipped mobile games that made real money. This is what matters most. We want to see games you've built that people actually played and paid for. - A deep understanding of what makes games work — retention, progression, monetisation, and how to plan and grow a game over time. - Fluency with Claude Code / AI-assisted development. We build fast with modern tools. Your coding language doesn't matter — your judgment and output do. A strategic, ownership mindset. Someone who can take the vision and run with it, not wait for instructions. - Bonus if you've worked with on-device ML / camera detection, Flutter, or monetisation for family audiences — but a great game-maker comes first. HOW TO APPLY Don't send a generic proposal — we'll ignore it. Instead, tell us: - The games you've shipped, with links, and the revenue or downloads they achieved. - One thing you did that meaningfully improved a game's retention or revenue, and how. - Whether you've used Claude Code or similar AI development tools, and how. Start your reply with the word "PUNCH" so we know you read this properly. We're looking for the right person and will pay accordingly for proven talent. We will even provide commission based off the revenue the app generates
