About Drago Live
Drago Live is a live streaming + virtual gifting + gaming app (think Bigo/Poppo/Tango vibes) built with Flutter & Dart.
We use ZEGOCLOUD UI Kit & SDK for live video, beauty filters, PK battles, audio rooms, and more.
We’re scaling fast and need a senior engineer who knows ZEGOCLOUD inside out.
Role
Own the end-to-end integration and optimization of ZEGOCLOUD features in our Flutter app across Android and iOS—from beauty filters to PK battles and moderation controls—while keeping performance silky smooth and battery-friendly.
What you’ll build
- Live Streaming: host/guest flows, co-hosting, PK battles, multi-guest, invite/signaling.
- Beauty/Effects: beauty filters, stickers/overlays, effect intensity controls, device-adaptive quality.
- Realtime Comms: 1:1 & group video/voice calls, audio rooms, spatial audio (if supported).
- Chat & Signaling: room chat, reactions, gifts, robust reconnect & state sync.
- Room Management: create/join/end, seat management, permissions, host tools.
- Moderation: mute/kick/ban, content safeguards, report flows, admin dashboards hooks.
- Virtual Gifting: gift animations, lucky gifts, combos, gift-led events & counters.
- Performance: fps/bitrate tuning, thermal & energy optimization on iOS, crash-free stability.
- Platform Plumbing: push notifications, deep links/universal links, background modes (nice to have).
Must-have skills
- 3+ shipped Flutter apps with substantial ZEGOCLOUD UI Kit/SDK integration.
- Strong grasp of ZegoExpressEngine concepts: rooms, streams, tokens, signaling.
- Implemented beauty filters, PK battles, audio rooms, stickers, and virtual gifting in production.
- Proven performance tuning: bitrate ladders, CPU/GPU tradeoffs, device gating, thermal handling (iOS).
- Solid iOS & Android platform chops: entitlements, background modes, permissions, ProGuard/obfuscation.
- CI/CD familiarity for Flutter (fastlane, code signing, Play/App Store basics).
Nice to have
- Experience with Parse Server or similar BaaS, Firebase Messaging, Dynamic/Universal Links.
- Anti-abuse/mod tooling (rate limits, moderation queues).
- Analytics & A/B testing for engagement features.
Hardware / Work setup
- MacBook required (for iOS builds/signing).
- iPhone preferred for on-device testing (Android device also preferred).
- Remote OK;
strong async communication and fast iteration expected.
Success looks like
- <
2s stream start time ongood networks.
- <
300ms end-to-end latency for interactive features (where feasible).
- <
1% crash rate;
no iOS thermal throttling under common presets.
- Smooth PK/beauty/gifting at scale with clean room state and zero “ghost” sessions.
Engagement
