Descrição da oferta de emprego

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 where applicable; 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 and keep specs tidy in Confluence and PRs clear.
• Attend daily standups in English and other ceremonies; keep Jira up to date and log time entries per task.
• Submit an end-of-day daily report in English including hours worked, completed tasks, 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.

Must-Haves

• Fluent English (spoken and written): comfortable in daily standups and EOD reports.
• Strong experience with Flutter and Dart building Desktop apps (preferably macOS).
• Proven work reducing CPU/GPU usage in Flutter apps 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, and Sentry for monitoring.
• Git proficiency, code reviews, CI (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.
• WebRTC experience; spatial audio; jitter/latency tuning.
• Android/iOS publishing (fastlane or equivalent), push notifications, in-app review flows.
• Docker, CDN, and networking basics for real-time apps.
• Accessibility 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 daily.
• Support for learning, events, and continuous improvement.
