• Invent new ways to compress and optimise Large Language Models with quantum‑inspired methods.
• Benchmark, stress‑test, and fine‑tune LLMs to boost accuracy, efficiency, and robustness.
• Build and deploy LLM‑powered apps – from RAG systems to AI agents.
• Act as an LLM specialist, spotting opportunities where quantum AI can make the impossible possible.
• Design and train custom deep learning models, not just for language, but also in computer vision and beyond.
• Keep experiments transparent with clear documentation, while driving innovation at speed.
• Mentor teammates, share knowledge, and help grow a culture of technical excellence.
• Stay ahead of the curve with the latest research, tools, and breakthroughs in AI.

What we’re looking for

• A degree in AI, Computer Science, Data Science (BSc, MSc, or PhD).
• 2+ years of hands‑on deep learning experience – designing, training, or fine‑tuning transformers or vision models.
• Strong track record with transformer models (Hugging Face Transformers, Accelerate, Datasets, etc.).
• Solid grasp of deep learning theory, training & inference.
• Excellent Python skills with PyTorch + Hugging Face expertise.
• Understanding of GPU architectures and LLM infrastructure.
• Hands‑on with AWS (or similar), Docker, and deploying models in production.
• Problem‑solver with sharp debugging, testing, and performance optimisation skills.
• Bonus points for published research in AI/deep learning.
