Job description

• 3 to 5 years shipping React Native apps that are live on the Play Store or App Store.
• A consumer app you helped grow past 100K active users, where crashes, slow screens and checkout drop-off had a measurable cost and you were the one who brought them down.
• Strong TypeScript and a deep grip on React Native: the new architecture, native modules, Reanimated and gestures, navigation, and profiling on real devices. You can explain why a screen is slow and fix it.
• A BFF (backend-for-frontend) layer and server-driven UI you have built or consumed in production. This is a big one: it is how we change screens and offers without a release.
• Observability and event SDKs wired properly: product analytics and session replay (PostHog or similar), crash reporting (Crashlytics or Sentry), and marketing and attribution SDKs such as MoEngage and the Meta SDK, with a clean event taxonomy that growth and ops can trust.
• Expo and EAS, or an equivalent build, release and OTA pipeline.
• Automated testing as part of the feature, not after it: Jest, React Native Testing Library, and Maestro or Detox on real devices.
• Strong UI/UX sense and real empathy. You can design a flow when there is no mock, and you understand that someone ordering medicine is often anxious, in a hurry, or not fluent with phones. Confusion here is not a bug, it is a missed dose.
• Inclusive design you can show: apps built for elderly, low-literacy or first-time smartphone users, and the accessibility and readability choices you made.
• Performance-tier engineering: an app that adapts to low-end devices and slow networks, and the measurements you used to segment it.
• Comfort going native when needed: Kotlin for Android modules, logcat and the profiler.
• AI coding assistants in daily use, and proof they made you faster without lowering what you ship.
• Taste. Strong opinions about what a good mobile experience feels like, and a shipped app that shows them.
• Ownership. You've carried a product from design through launch through the production incident afterwards, without a QA team to hand it to.

Preferred

• Quick-commerce, healthcare, fintech or any consumer app where the first order and the repeat order were the metrics that mattered.
• Push and in-app campaign tooling beyond the SDK install: journeys, segments and deep links that land on the right screen.
• Firebase (Remote Config, Crashlytics, Realtime Database) and a cloud platform (AWS preferred).
• Hardware-adjacent mobile work: camera and barcode scanning, background location, foreground services.
• Swift and iOS experience, for when the app crosses over.
• Startup or product-company experience where you were one of a handful of engineers.

Who You Are

• High agency. You see a problem, you own it, and you tell people what you did rather than asking whether you may start.
• Taste. You can tell the difference between an app that works and an app that feels right, and you care enough to close the gap.
• Empathy. You picture the person on the other side of the screen, and you know that for medicines the stakes are higher than for groceries.
• All users, not the median one. The 60-year-old on a budget phone with poor eyesight is your benchmark, not an edge case.
• Bias to delete. You'd rather remove a screen than add a setting. Simplicity is a feature you fight for.
• Ship, then watch. Replays, crash logs and a chat with a customer tell you more than a sprint review.
• Whole-surface owner. Happiest in a small team where the app is yours, and comfortable in the backend or native code when it needs you.
• AI-native, still accountable. You use AI tools to move faster, and you still read every line that goes out under your name.
• Close to the stores. You enjoy a fast pace and a 6-day week in the office, because the stores run every day and you want to be near them.

What You'll Get

• Health insurance for you and your family.
• A top-of-the-line device and the tools you need to do your best work.
• ESOPs: own a piece of the company you're helping build.
• Real users, every day: the people using your app sit a short ride away, and you'll meet them
