The perfect candidate should have strong Python programming skills, hands-on experience with data manipulation, and a solid background in machine learning, particularly in classification and retrieval tasks. This role requires practical experience with large language models, NLP, retrieval-augmented generation, prompt engineering, and modern ML development tools.

Requirements

• A solid background in machine learning, particularly in classification and retrieval tasks, as well as hands-on experience with large language models (LLMs), including fine-tuning for specific use cases, retrieval-augmented generation (RAG), foundation model APIs, and prompt engineering.
• Strong understanding of programming with Python.
• Solid knowledge of machine learning and artificial intelligence.
• Experience with classification and retrieval tasks.
• Hands-on experience with large language models.
• Experience with at least some of the following:
  • LLM fine-tuning;
  • Retrieval-augmented generation;
  • Foundation model APIs;
  • Prompt engineering.
• Knowledge of Pandas and NumPy.
• Good understanding of NLP concepts.
• Familiarity with Hugging Face Transformers and Datasets.
• Familiarity with Faiss or similar nearest-neighbor search tools.
• Experience with Hydra for configuration management.
• Experience with Weights & Biases for experiment tracking.
• Experience with Git and GitHub.
