Unreal Engine Developer (Web-Based Educational Platform)

Requirements:

• 5+ years of experience with Unreal Engine 4/5, with deep knowledge of C++ gameplay systems and Blueprint scripting.
• Strong background in Unreal Engine Web deployment (e.g., Pixel Streaming, WebRTC, WebAssembly/Emscripten builds).
• Proficiency in API integration within Unreal (REST/HTTP requests, JSON serialization/parsing, WebSockets).
• Experience with real-time audio processing inside Unreal: microphone input capture, Text-to-Speech (TTS)playback, Speech-to-Text (STT) pipelines, and lip-sync/phoneme-based animation.
• Solid understanding of Animation Blueprints, Live Animation Playback, Sequencer, and Control Rig for real-time character animation.
• Familiarity with third-party SDK integration into Unreal (AI, biometrics, or educational technology SDKs).
• Proven skills in low-latency system optimization: network sync, audio/animation pipeline tuning, and Unreal performance profiling (Stat commands, Unreal Insights, GPU/CPU profilers).
• Strong problem-solving ability and experience building scalable interactive systems.
• (Nice-to-have) Experience in serious games, edtech applications, or interactive training simulations.
• (Nice-to-have) Familiarity with emotion recognition, gaze tracking, or AI-driven character behavior systemsintegrated with Unreal.
• Upper-intermediate on Advanced English or French proficiency.
   

Responsibilities:

• Implement real-time communication between Unreal Engine client and Python backend (REST APIs, WebSockets), handling JSON-based lesson data, animation keyframes, and student progress updates.
• Integrate microphone input into the Unreal Engine runtime for speech capture and recognition.
• Implement TTS playback within Unreal with synchronized lip-sync and facial animation via Animation Blueprints / MetaHuman Face AR.
• Receive animation data (key sets, skeletal poses, blendshapes) from backend and render them through Sequencer or real-time animation playback.
• Ensure audio-visual synchronization: align speech, gestures, and expressions for natural teacher–student interaction.
• Optimize Unreal for browser/streaming environments (memory footprint, bandwidth usage, latency).
• Profile and optimize rendering, animation, and networking pipelines for smooth interaction on both desktop and cloud-streamed clients.

Project description: 

We are building an AI-powered educational platform that combines Unreal Engine’s real-time animation with AI-driven teaching assistants. Students interact with a virtual teacher avatar that responds via speech, gestures, and animations in real-time. Unlike traditional games, this project emphasizes web deployment, low-latency interactions, and AI integration rather than core gameplay mechanics.
The platform includes:
 

• 3,000+ grammar exercises, 500 retention checks, 200 dictations, and 300 instructional videos.
• Real-time progress tracking, attention-level monitoring with BioTrack technology, and adaptive lesson planning.
• Multi-modal student interaction (voice, selections, handwriting, keyboard input).
• An engaging gamified learning journey, awarding badges and recognition for mastery.
   

Our mission: to revolutionize language learning with technology that enhances teaching efficiency, makes grammar more engaging, and adapts to every learner’s needs.
