• 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.
