• Experience with numerical methods, geometric processing, physical simulation, or generative models (GAN, VAE)
• Proven experience fine-tuning and deploying computer vision models for real-time or streaming use cases
• Hands-on skills with LoRA training, model post-processing, and on-device inference optimisation
• Proficiency in backend development (Python, Go) and model-serving architectures
• Practical knowledge of computer graphics APIs (OpenGL/OpenGLES) and shader development (GLSL/HLSL)
• Full proficiency in English communications

Preferred Qualifications

• Experience with AI effect tools, video post-production, or multimedia ML use cases
• Experience with mobile image processing
