Descrição da oferta de emprego

Our client is seeking multiple tech roles with remote options. The descriptions below summarize responsibilities, qualifications, and context while preserving original intent and content where possible.

Senior Flutter Developer

Location: Remote

Contract: PJ (full-time)

Level: Senior

We’re building a virtual office platform for remote and hybrid teams. It includes persistent rooms, real-time presence, audio/video (WebRTC), chat, screen sharing, collaborative boards, and immersive spaces to boost connection, productivity, and team cohesion.

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 (WebSockets/Streams).
• Implement audio/video features (e.g., flutter_webrtc): device selection, camera/mic permissions, I/O routing, and stability under variable networks.
• Ensure end-to-end observability: instrument 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 documentation.
• 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; keep specs tidy in Confluence and PRs clear.
• Attend daily standups in English and other ceremonies; keep Jira up to date and log time per task.
• Submit an end-of-day daily report in English including hours, progress, blockers, and tomorrow’s plan.
• Secondary (Android & iOS): maintain parity when applicable, fix platform-specific issues, assist with CI/CD and store releases, monitor crashes/perf via Sentry and review UX insights with Clarity when relevant.

Requirements

• Fluent English (spoken and written).
• Strong experience with Flutter and Dart building Desktop apps (preferably macOS).
• Proven track record of reducing CPU/GPU usage in Flutter apps with measurable 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.
• Experience with Firebase (Auth, Firestore, Analytics) or equivalent, plus Microsoft Clarity and Sentry.
• 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, and 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 every day.
• Support for learning, events, and continuous improvement.
