AI Android Developer
About this role
<p><br><strong>The POS (Point of Sale) is the heartbeat of a restaurant. When it stops, everything stops. You'll make sure it never stops.</strong></p><hr class="border-border-200 border-t-0.5 my-3 mx-1.5"><p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">Karma is building the restaurant operating system Europe deserves. We're 20 people competing against giants - and winning deals with 500+ location chains. Our secret? We build with AI, ship fast, and refuse to accept "that's how it's always been done."</p><p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">Now we need someone to own Android. </p><hr class="border-border-200 border-t-0.5 my-3 mx-1.5"><p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><strong>What you'll build:</strong></p><p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><strong>Point of Sale that actually works.</strong> Fast. Bulletproof. Offline-first. Restaurants don't stop when WiFi drops—neither does your code. You'll build native Android POS that handles payments, syncs seamlessly, and survives the chaos of a Friday night dinner rush.</p><p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><strong>Kitchen Display Systems that think.</strong> Real-time order routing. Smart ticket management. Prep time predictions. The KDS isn't just a screen—it's the brain of the kitchen, and you'll make it intelligent.</p><p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><strong>The full hardware dance.</strong> Payment terminals. Receipt printers. Cash drawers. Card readers. NFC. You'll integrate with all of it and make it feel effortless.</p><p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><strong>AI-native features.</strong> Voice ordering. Intelligent upselling. Predictive workflows. We're not adding AI as a feature—we're building AI into the foundation.</p><hr class="border-border-200 border-t-0.5 my-3 mx-1.5"><p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><strong>The technical reality:</strong></p><p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">Kotlin. Offline-first architecture. Local databases that sync when they can and never lose a transaction. Payment SDK integrations. Hardware APIs. Performance optimization for devices that run 14-hour shifts. Error handling that would make a spacecraft engineer nod approvingly. You'll use our modular home built SDK for backend that's already powering Karma OS on the web today.</p><hr class="border-border-200 border-t-0.5 my-3 mx-1.5"><p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><strong>Who you are:</strong></p><p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">You've built Android apps that can't afford to crash. You understand that "works on my device" means nothing when it's 8pm on a Saturday and the kitchen is on fire (metaphorically, hopefully).</p><p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">You use AI to move faster. Cursor, Claude Code, whatever makes you dangerous. You're not threatened by the shift - you're accelerated by it.</p><p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">You obsess over the details that separate "functional" from "exceptional." Milliseconds matter. Edge cases matter. The loading spinner that nobody should ever see matters.</p><hr class="border-border-200 border-t-0.5 my-3 mx-1.5"><p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><strong>Why this matters:</strong></p><p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">Restaurants run on razor-thin margins. A clunky POS costs them money every single day. A KDS that lags means cold food and angry customers. What you build directly impacts whether these businesses thrive or just survive.</p><hr class="border-border-200 border-t-0.5 my-3 mx-1.5"><p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><strong>Why Karma:</strong></p><p class="font-claude-response-body break-words wh
