Strong skills to communicating complex research for public audiences or peers
Experience developing machine learning algorithms in e.g. Python, PyTorch, C/C++

Nice to have:

Research experience in generative AI, especially in building and optimising large language models for areas of audio/ speech processing and understanding, computer vision and/or natural language understanding beyond black-box use
Additional AI research experience in computer vision and/or NLP
Previous internship(s) and/or research assistantship(s) in an AI research organization
Industry experience working on Speech, Language, and LLM related topics and the experience to apply relevant AI and machine learning techniques to build intelligent rich speech & language systems for improving product experiences
