What we're looking for

We’re looking for an MLE with both technical depth and creative instinct — someone who thrives in fast-moving, cross-disciplinary environments. You’ll bring:

• Academic or practical background in computer graphics, computer vision, or computer animation — with experience in one or more of: numerical methods, geometric processing, physical simulation, character animation, generative models (GAN, VAE), or mobile image processing.
• Proven experience fine-tuning and deploying computer vision models, particularly for real-time or streaming use cases.
• Hands-on skills with LoRA training, model post-processing (quantization, pruning), and on-device inference optimisation.
• Familiarity with image and video ML models and how they integrate into visual or rendering pipelines.
• Proficiency in backend development (e.g., Python, Go) and model-serving architectures.
• Practical knowledge of computer graphics APIs (OpenGL/OpenGLES) and shader development (GLSL/HLSL).
• Experience with AI effect tools, video post-production, or multimedia ML use cases is a strong bonus.
• A mindset that balances research curiosity with rapid product iteration.
• Full proficiency in English communications.

任职要求

• 拥有计算机图形学、计算机视觉或计算机动画的学术或项目经验，熟悉以下一项或多项：数值方法、几何处理、物理仿真、角色动画、生成模型（GAN、VAE）或移动端图像处理
