Descrição da vagaMinimize rebuilds : effective state selection (BLoC / Riverpod / Provider), const constructors, proper Keys , split large widgets. Cut redundant layout / work : avoid heavy logic in build, cache computed values, reduce intrinsic measurements, coalesce events, debounce / throttle streams. Move heavy tasks off the UI thread : isolates (compute / custom), lazy JSON parsing, incremental work units. Frame scheduling discipline : prevent setState loops; render only when state actually changes. Reduce overdraw / repaints : place RepaintBoundary wisely; optimize CustomPainter (shouldRepaint); avoid large Opacity on complex subtrees. Avoid expensive effects : minimize saveLayer , heavy blurs / gradients and big shadows . Use right-sized images & filterQuality (low / none when acceptable); limit transforms on large layers. Shader jank control : warm up shaders / capture SkSL where applicable; keep fragment shaders simple. Pause / disable animations when off-screen; keep animation count / area minimal. Profile with Flutter DevTools (CPU / GPU / frame timeline) and add perf budgets (avg CPU% / GPU frame time) to CI gates. Track before / after metrics per feature; regressions must be fixed before release. Fluent English (spoken and written) : comfortable in daily English standups and writing EOD reports. Strong experience with Flutter and Dart building Desktop apps (preferably macOS ). Proven work reducing CPU / GPU usage in Flutter apps (ideally desktop / macOS) with measurable before / after results. Solid grasp of architectural patterns ( MVC / MVVM / Clean ), DI , and state management (BLoC / Riverpod / Provider). Hands-on with RESTful APIs , WebSockets / Streams , async / isolates , and robust error handling. Firebase (Auth, Firestore, Analytics) or equivalent , Microsoft Clarity (for UX / session insights in web-embedded contexts), and Sentry for error / performance monitoring. Git proficiency, code reviews, CI (e.g., GitHub Actions / GitLab CI ), and Jira work logs / time tracking . Deep macOS expertise : signing, notarization , App Sandbox , entitlements, Keychain, packaging, and updater pipelines. Practical WebRTC experience; spatial audio; jitter / latency tuning. Android / iOS publishing (fastlane or equivalent), push notifications, and in-app review flows. Docker , CDN , and networking basics for real-time apps. Accessibility (VoiceOver / TalkBack) and internationalization. Remote-first, flexible hours, and competitive market range . Fast feedback loops, ownership, and a product with real impact on how teams work every day. Support for learning, events, and continuous improvement.
Senior Flutter Developer
Location : Remote
Contract : PJ (full-time)
Level : Senior
We’re building a virtual office platform for remote and hybrid teams. It brings together persistent rooms , real-time presence , audio / video (WebRTC) , chat , screen sharing , collaborative boards , and immersive spaces to boost connection, productivity, and team cohesion — all in one place.
The Role
We’re looking for a Senior Flutter Developer focused on macOS Desktop to build and evolve our desktop client. You’ll ship a high-performance, stable, and well-instrumented app that integrates video / audio, real-time features, and collaborative tools—while keeping top-tier code quality, testing, and documentation.
Secondary scope : help maintain Android and iOS builds (feature parity, fixes, and releases).
What You’ll Do
- Design, build, and maintain the Flutter macOS app with clean architecture, modular layers, and reliable state management .
- Integrate RESTful APIs and real-time services (e.g., WebSockets / Streams ).
- Implement A / V features (e.g., flutter_webrtc) : device selection, camera / mic permissions, I / O routing, and stability under variable networks.
- Ensure observability end to end : instrument product events / metrics; triage errors with Sentry ; capture UX signals with Microsoft Clarity (session replay / heatmaps) where applicable (web / embedded views); analyze performance traces and dashboards.
- Own quality : unit, widget, and integration tests; CI checks; code reviews; technical docs.
- Handle macOS distribution : code signing & notarization , entitlements, Hardened Runtime , App Sandbox , Keychain; package DMG / PKG ; manage auto-update (e.g., Sparkle).
- Collaborate with Product / Design / QA to refine requirements, edge cases, and acceptance criteria; keep specs tidy in Confluence and PRs clear.
- Team rituals & reporting :
- Attend daily standups in English and other ceremonies (planning, grooming, demos, retros).
- Keep Jira up to date (status, links, attachments) and log time entries (work logs) per task.
- Submit an end-of-day (EOD) daily report in English including : hours worked (per task), what was completed, current task & ETA, blockers, and plan for tomorrow.
- Secondary (Android & iOS) : maintain parity when applicable, fix platform-specific issues, help with CI / CD and store releases , monitor crashes / perf via Sentry and review UX insights with Clarity when relevant.
