Founding Flutter Engineer

We’re building the future of education and are looking for a highly skilled **Flutter Engineers** who can help us ship a world-class mobile experience to lakhs of students, we’re looking for someone who thrives in a fast-paced environment and are comfortable navigating ambiguity. You won't just be writing code; you will be architecting systems. Ideally, you are someone who can take a vague problem statement, convert it into technical requirements, and build a scalable solution from the ground up. ### **What You’ll do** - **App Architecture & State Management:** Design and build scalable Flutter apps using **GetX** for state management, routing, and dependency injection. Set conventions for package structure, controllers, bindings, and services that the rest of the team can follow without friction. - **Test-Driven Development:** Write code with **TDD** as a default. Build a strong base of **unit tests, widget tests, and integration tests** so we ship fast without breaking what already works. We believe tests are a Pillar of shipping fast in right manner. - **Performance & Memory:** Use the **Flutter DevTools profiler** to hunt down jank, rebuild issues, and memory leaks. Understand how the Dart VM manages memory, how `Image` caches behave, how `ListView.builder` differs from a naive list, and other performance pitfall. Keep the app smooth on entry-level Android devices, not just flagship phones. - **Audio & Video Playback:** Own the playback layer — background audio, lockscreen controls, video players, buffering, caching, and resuming. - **Payments:** Integrate and maintain **payment gateway** flows (Razorpay/Cashfree). Handle **payment idempotency**, retries and failure recovery so we never double-charge a user or lose a successful payment to a flaky network. - **Notifications & Networking:** Set up **push notifications** (FCM), handle foreground/background/terminated states, deep links, and notification routing. Build clean **API interceptors** for auth tokens, refresh flows, retries, error normalization, and request/response logging. - **Feature Flags & Remote Config:** Use **Firebase Remote Config** and feature flags to ship new features with gradual rollouts, kill-switch broken features, and A/B test product hypotheses without a forced app update. - **End-to-End Ownership:** Debug across the stack, work with backend engineers on API contracts, and translate basic requirements into shipped features with minimal hand-holding. Crash triage via Crashlytics, and post-release monitoring. - **Lead:** Guide junior and mid-level Flutter engineers, review PRs with intent, and help the team grow and execute faster. ### What you bring - **Core Stack:** Strong proficiency in **Flutter** and **Dart**, with 3+ years of production Flutter experience. - **State Management:** Deep, hands-on experience with **GetX** — controllers, bindings, reactive state, routing, and dependency injection. - **Testing:** Strong practice of **TDD**, **unit tests**, **widget tests**, and **integration tests**. You've used `mockito`/`mocktail`, `flutter_test`, and `integration_test` in production codebases. - **Performance:** Hands-on with the **Flutter DevTools profiler**, timeline view, memory view, and CPU profiler. You can read a flame chart and explain why a frame dropped. - **Memory Management:** Solid understanding of Dart's memory model, GC behavior, image caching, stream disposal, and common leak patterns in Flutter. - **Audio/Video:** Production experience with `just_audio`, `audio_service`, `media_kit`, or equivalent. Comfortable with background playback, media notifications, and HLS streaming. - **Payments:** Shipped at least one app with a real payment gateway integration. Understand **idempotency keys**, retry semantics, and reconciliation. - **Firebase:** Comfortable with **FCM, Remote Config, Crashlytics, Analytics**, and OTP based authentications. - **Networking:** Solid command of `dio` or `http`, request **interceptors**, token refresh, retry logic, and caching. - **Release Engineering:** Shipped apps to both **Play Store and App Store**. You know signing configs, provisioning profiles, App Store Connect, and staged rollouts. - **Tools:** **Git, Firebase CLI**, and standard CI/CD workflows (GitHub Actions). ### **Nice to Have** - Experience with native Android (Kotlin) or iOS (Swift) for writing platform channels when Flutter falls short. - Previous experience in a high-growth product based startup and have seen their journey. - Ability to incorporate AI tools into daily engineering workflows to drive efficiency and deliver higher quality outcomes - Experience with **Supabase** - Familiarity with **CI/CD setup** for Flutter ### **Culture Fit** - **Adaptive to Ambiguity:** You are comfortable working in a dynamic environment where requirements may shift. You can move forward without having every single detail defined upfront. - **Problem Solver:** You view technical challenges as puzzles to be solved, not blockers. - **Self-Starter:** You have a track record of building mobile apps from basic requirements and owning the release pipeline. - **Quality-Obsessed:** You believe shipping fast and shipping right are not in conflict — they're enabled by tests, profiling, and feature flags. - **AI Evangelist:** You ship faster with AI, spend enough time in design and planning, and then let the models do their magic with proper guardrails (unit/integration tests for faster executions).
