You will be at the forefront of creating natural and engaging communication experiences—including voice, facial expressions, and gestures—across various platforms: Mobile (iOS/Android), PC, and WebGL.

Key Responsibilities

• Develop the Unity client using C# to create a real-time conversational experience with 3D and 2D avatars.
• Integrate with internal AI services to ensure smooth, low-latency dialogue.
• Implement expressive controls for avatars:
• Program real-time lip-sync and facial expressions (blendshapes/rig) synchronized with audio.

Manage and optimize 3D assets:

• Integrate 3D models (FBX, OBJ, GLB, etc.) into Unity.
• Manage lighting, materials, and animations to ensure optimal performance while maintaining high visual quality.

Collaborate cross-functionally:

• Work closely with 3D Artists and Animators to optimize models and animations for superior performance on Unity.
• Partner with Product and Design teams to conduct A/B testing, gather feedback, and continuously improve the interactivity and naturalness of the avatar.

Your skills and experience

• At least 3 years of hands-on experience in game or application development with Unity and C#.
• Solid understanding of the basic 3D pipeline: rigging, skinning, blendshapes, and common formats like FBX and GLTF. Experience working with Blender or Maya is a significant advantage.
• Proven experience in comprehensive performance optimization for Unity projects across multiple platforms.
• A product-oriented mindset with a strong focus on user experience.
• Excellent communication skills and a proactive approach to teamwork.
• Ability to read and understand technical documentation and SDKs in English fluently.
