We're on a mission to revolutionize remote and hybrid work. Our virtual office platform brings together various tools and features that foster connection, productivity, and team cohesion in one seamless space.
The Role
You'll be working as a Senior Flutter Developer, focusing on building and evolving our macOS desktop client. Your primary objective will be to develop a high-performance app that integrates video/audio, real-time features, and collaborative tools while maintaining top-notch code quality.
* Design, build, and maintain the Flutter macOS app with clean architecture, modular layers, and reliable state management.
* Integrate RESTful APIs and real-time services, such as WebSockets/Streams.
* Implement A/V features like device selection, camera/mic permissions, I/O routing, and stability under variable networks.
* Ensure observability: instrument product events/metrics; triage errors with Sentry; capture UX signals where applicable; analyze performance traces and dashboards.
* Own quality: unit, widget, and integration tests; CI checks; code reviews; technical documentation.
* Handle macOS distribution: code signing & notarization, entitlements, Hardened Runtime, App Sandbox, Keychain; package DMG/PKG; manage auto-update.
* Collaborate with Product/Design/QA to refine requirements, edge cases, and acceptance criteria.
CPU & GPU Optimizations
**CPU Optimization Strategies:
* 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 Optimization Strategies:
* 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.
