We're creating a virtual office platform for remote and hybrid teams. It integrates persistent rooms, real-time presence, audio/video (WebRTC), chat, screen sharing, collaborative boards, and immersive spaces to boost connection, productivity, and team cohesion in one place.
The Role
1. Develop the Flutter macOS app with clean architecture, modular layers, and reliable state management.
2. Integrate RESTful APIs and real-time services such as WebSockets/Streams.
3. Implement A/V features like device selection, camera/mic permissions, I/O routing, and stability under variable networks using flutter_webrtc.
4. Evaluate observability end to end: instrument product events/metrics; triage errors with Sentry; capture UX signals with Microsoft Clarity where applicable; analyze performance traces and dashboards.
5. Ensure quality by implementing unit, widget, and integration tests; CI checks; code reviews; technical documentation.
6. Manage macOS distribution including code signing & notarization, entitlements, Hardened Runtime, App Sandbox, Keychain; package DMG/PKG; handle auto-update using Sparkle.
7. CPU & GPU Optimizations:
* Minimize rebuilds by selecting effective state (BLoC/Riverpod/Provider), using const constructors, proper Keys, splitting large widgets.
* Reduce 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 using isolates (compute/custom), lazy JSON parsing, incremental work units.
* Prioritize frame scheduling discipline: prevent setState loops; render only when state actually changes.
* Reduce overdraw/repaints: wisely place RepaintBoundary; optimize CustomPainter (shouldRepaint); minimize 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.
* Control Shader jank: warm up shaders / capture SkSL where applicable; keep fragment shaders simple.
* Pause/disable animations when off-screen; maintain minimal animation count/area.
Must-Haves
* Fluent English skills: comfortable in daily standups and writing reports.
* Strong experience with Flutter and Dart building Desktop apps preferably on macOS.
* Proven work reducing CPU/GPU usage in Flutter apps with measurable results.
* Grasp architectural patterns (MVC/MVVM/Clean), Dependency Injection, and state management (BLoC/Riverpod/Provider).
* Hands-on with RESTful APIs, WebSockets/Streams, async/isolates, and robust error handling.
* Familiarity with Firebase (Auth, Firestore, Analytics) or equivalent, Microsoft Clarity for UX insights, and Sentry for monitoring.
* Git proficiency, code reviews, CI (e.g., GitHub Actions/GitLab CI), and time tracking.
