We are an AI-first company

We don't just build software. We build intelligent systems. From AI-assisted development workflows to LLM-powered product features, we expect every engineer to embrace and actively shape how AI changes what we ship and how we ship it. If you're the kind of engineer who gets excited by what's possible when agents, models, and great product sense meet, you'll feel at home here.

Join Zapp and take full lifecycle ownership of the apps our customers use every day. We're building a world-class experience across iOS, Android, and web, and you'll help us get there.

Quick commerce moves fast and lives in the real world. AI is changing how we build it. That's the part we love. We need engineers who are curious, energetic, and thrive at the front line of both.

• Build a world-class customer experience. Develop the mobile and web experiences our customers use every day, in React Native and Expo across iOS, Android, and web.
• Bring AI into how we build. Use AI in your daily work. Share patterns that help the team move faster, and learn from what others discover.
• Lead how AI shows up in our product. Set the direction on where AI creates real customer value, prototype the hardest bets yourself, and bring the team with you.
• Own delivery end-to-end. Pick up a problem, design the solution, ship the mobile work, write the backend code when the feature requires it, and see it through to production.
• Own on-call. Be on the rotation, and stand behind what you ship in production.
• Keep the app fast and trusted. Profile performance, harden release processes, and protect production health.
• Set the technical direction. Own the architecture, patterns, and standards other engineers build on — across the mobile stack, not just your own work. Lift the people around you.

If most of these land for you, please apply. We hire on trajectory and curiosity as much as CV.
