Senior Flutter Developer

Senior Flutter Developer - Detalhes da Vaga. ? 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 Were looking for a Senior Flutter Developer focused on macOS Desktop to build and evolve our desktop client. ? Youll ship a high-performance, stable, and well-instrumented app that integrates video/audio, real-time features, and collaborative toolswhile keeping top-tier code quality, testing, and documentation. ? Secondary scope: help maintain Android and iOS builds (feature parity, fixes, and releases). ? What Youll 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. ? CPU & GPU Optimizations (primary focus) CPU Minimize 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. ? GPU 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. ? Measurement & Guardrails: 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. ? Must-Haves 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 . ? Nice to Have 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. ? Benefits & Environment 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. ? . Requisitos para participar do processo. ? . O que oferecemos.
