About Us
We are a remote-first team looking for experienced professionals to help us shape the future of virtual office platforms.
The Role
* We're seeking a skilled Senior Flutter Developer to join our team and work on building innovative virtual office solutions for remote and hybrid teams. Your primary focus will be on designing, developing, and maintaining our Flutter macOS application with clean architecture and reliable state management.
* You'll be responsible for integrating RESTful APIs and real-time services into our platform, ensuring seamless communication between different components.
* As a senior developer, you'll also implement A/V features using WebRTC, manage device selection, camera/mic permissions, I/O routing, and optimize performance under variable network conditions.
* We emphasize observability and ensure that our product is well-instrumented, enabling us to track events, metrics, errors, and UX signals effectively. You'll use tools like Sentry for error tracking and Microsoft Clarity for session replay and heatmaps.
* Quality is paramount in our development process. As a member of our team, you'll own quality by writing unit, widget, and integration tests, performing CI checks, participating in code reviews, and contributing to technical documentation.
* Our macOS distribution requires expertise in code signing, notarization, entitlements, Hardened Runtime, App Sandbox, Keychain, packaging, and managing auto-update processes (e.g., Sparkle).
* You'll collaborate closely with Product/Design/QA teams to refine requirements, edge cases, and acceptance criteria. We maintain a tidy Confluence for specs and clear PRs.
* Team rituals include daily standups in English and other ceremonies (planning, grooming, demos, retros). You'll keep Jira up-to-date with status updates, links, attachments, and log time entries per task. Daily EOD reports are expected in English, detailing hours worked, completed tasks, current task & ETA, blockers, and plans for the next day.
* We encourage parity across Android and iOS platforms when applicable. This involves fixing platform-specific issues, assisting with CI/CD and store releases, monitoring crashes/perf via Sentry, and reviewing UX insights with Clarity when relevant.
CPU & GPU Optimizations
CPU
* To minimize rebuilds, we rely on effective state selection using BLoC/Riverpod/Provider, const constructors, proper Keys, and splitting large widgets.
* Cutting redundant layout/work involves avoiding heavy logic in build, caching computed values, reducing intrinsic measurements, coalescing events, debouncing/throttling streams, and moving heavy tasks off the UI thread using isolates/compute/custom.
* Frame scheduling discipline is essential to prevent setState loops; render only when state actually changes.
GPU
* We reduce overdraw/repaints by placing RepaintBoundary wisely, optimizing CustomPainter (shouldRepaint), and avoiding large Opacity on complex subtrees.
* Avoiding expensive effects includes minimizing saveLayer, heavy blurs/gradients, and big shadows.
* We limit transforms on large layers, use right-sized images, filterQuality (low/none when acceptable), and warm up shaders/capture SkSL where applicable.
* Pause/disable animations when off-screen, keeping animation count/area minimal.
Measurement & Guardrails
* We 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, with regressions 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).
* Familiarity 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.
