AI Engineer

Key Responsibilities: • Support the production and continual improvement of scalable and optimised AI/ML models, including multimodal large language models (LLMs), covering supervised fine-tuning (SFT), knowledge distillation, and large-scale distributed pre-training on 1000+-card GPU/NPU clusters. • Build algorithms and automated pipelines for the extraction, transformation and loading (ETL) of large volumes of unstructured multimodal data (text, images, video and audio) — including data quality inspection, data format transformation and version management — to deploy AI solutions from theoretical data science models into production, including real-time on-device inference scenarios. • Design multimodal evaluation benchmarks and automated evaluation pipelines; run experiments to test the performance of trained and deployed models; identify and resolve bugs and quality issues in models, data and evaluation pipelines, using evaluation results as feedback to drive the next iteration of training data and strategies. • Optimise model efficiency for deployment through quantization (PTQ/QAT), distillation and pruning; analyse MoE model inference workloads to support system-level optimisation. • Work in a team setting and apply knowledge of statistics, scripting (Python) and deep learning frameworks (PyTorch, MindSpore), collaborating with data, training, inference and product teams. • Work with the hardware and software platforms on which models are trained and deployed: run training on large Ascend NPU clusters; on deployment platforms (e.g. TensorRT), set up inference validation environments, confirm model structure and operator compatibility, and benchmark quantized models for accuracy and speed, covering both cloud and on-device inference. • To collaborate and communicate directly with Chinese speaking officers, stakeholders, counterparts, and customers in China HQ team. Required Skills & Qualifications: • Master's degree in Computer Science, Automation, Control Engineering, Electronic Engineering or a related technical field. • Minimum 5 years of work experience in an AI engineer role covering AI model training, evaluation and deployment. • Strong foundation in statistics, deep learning theory and model evaluation methodology. • Proficiency in Python scripting and at least one mainstream deep learning framework (PyTorch or MindSpore). • Hands-on experience with multimodal model pre-training, SFT and evaluation on large Ascend NPU clusters (1000+ cards), including evaluation benchmark design and large-scale unstructured data processing. • Experience in model compression (quantization/distillation) and efficient inference deployment on cloud and edge platforms. • Experience in direct technical engagement with external customers and technology partners. • Proficiency in Mandarin is essential to ensure effective communication with the Chinese-speaking stakeholders, including head office, business counterparts, and customers based in China.
