About a Live Streaming and Gaming App

The app is built with Flutter & Dart. We use ZEGOCLOUD UI Kit & SDK for live video, beauty filters, PK battles, audio rooms, and more.

Role

We are seeking a senior engineer who owns 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.

  • 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.

Requirements

  • 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).

Preferred Skills

  • 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.

Setup

  • MacBook required (for iOS builds/signing).
  • iPhone preferred for on-device testing (Android device also preferred).

Remote work arrangement expected.

Success metrics:

  • < 2s stream start time on good networks.
  • < 300ms end-to-end latency for interactive features (where feasible).
