Zegocloud flutter engineer (android & ios)

About Drago LiveDrago 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.RoleOwn the end-to-end integration and optimization of ZEGOCLOUD features in our Flutter app across Android and i OS—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 i OS, 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 Zego Express Engine 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 (i OS).
• Solid i OS & Android platform chops : entitlements, background modes, permissions, Pro Guard / obfuscation.
• CI / CD familiarity for Flutter (fastlane, code signing, Play / App Store basics).Nice to have
• Experience with Parse Server or similar Baa S, Firebase Messaging, Dynamic / Universal Links.
• Anti-abuse / mod tooling (rate limits, moderation queues).
• Analytics & A / B testing for engagement features.Hardware / Work setup
• Mac Book required (for i OS builds / signing).
• i Phone 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).
