ZEGOCLOUD Flutter Engineer

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 on good networks.

• < 300ms end-to-end latency for interactive features (where feasible).
