• Architect event-driven systems using:
  • Decoupled delegates
  • Event bus patterns
  • Unreal subsystems
  • Cross-system integration
• Implement MetaHuman runtime lip-sync systems, audio-to-viseme pipelines, and feed streamed audio into facial animation.
• Work with embedded Lua scripting and a Lua-driven data and logic layer, including C++/Lua bridge architectures.
• Perform audio and network debugging/profiling, including:
  • Tracing raw protocol events
  • Diagnosing audio quality
  • Latency and streaming issues

Qualifications

• Strong experience with UE5 C++ plugin/module development, runtime (non-editor) code, plugin boundaries, and integration patterns.
• Proven expertise in real-time audio streaming in Unreal Engine (USoundWaveProcedural, PCM buffering, resampling, sample-rate and audio-format handling, underrun mitigation, and latency tuning).
• Hands-on experience with WebSocket / streaming protocol integration in C++, including persistent session management, JSON-based event protocols, reconnection strategies, and backpressure handling.
• Experience with LLM / Conversational AI voice systems: TTS and STT integration, prompt and session design, turn-taking systems, and latency debugging.

• Experience with MetaHuman integration, runtime lip-sync systems, audio-to-viseme pipelines, and feeding streamed audio into facial animation.
• Proficiency with embedded Lua scripting, experience working with a Lua-driven data and logic layer, and familiarity with C++/Lua bridge architectures.
• Strong audio and network debugging/profiling skills: tracing raw protocol events, diagnosing audio quality issues, and diagnosing latency and streaming issues.
• Experience with libwebsockets is a plus.

Requirements

• Experience with StateTree in Unreal Engine.
• Background in gameplay systems and components.
• Knowledge of multiplayer replication.
• Proficiency with Blueprints.
• Experience with animation systems.
