Responsibilities:

  • Design, develop, and optimize LLMs and NLP models for various applications, such as text classification, named entity recognition, sentiment analysis, and question answering.
  • Fine-tune pre-trained LLMs (e.g., GPT, BERT, T5) on specific tasks using domain-specific data.
  • Work closely with cross-functional teams to integrate NLP solutions into products and services.
  • Continuously monitor, evaluate, and improve the performance of deployed models, addressing issues such as bias, fairness, and accuracy.
  • Contribute to the development and maintenance of NLP pipelines and workflows, including data preprocessing, model training, and inference.
  • Design and develop retrieval algorithms and models, including TF-IDF, BM25, and vector-based methods, to enhance search relevance and efficiency.
  • Design, develop, and optimize hybrid workflows integrating LLMs with retrieval algorithms.

Requirements:

  • Bachelor’s degree in Computer Science, Data Science, Applied Mathematics, or a related field. A Master’s degree is a plus.
  • 2-5 years of experience in machine learning and NLP, with experience in LLMs and retrieval systems.
  • Knowledge of transformer architectures and experience implementing them in NLP tasks.
  • Experience with data preprocessing techniques for text data, including tokenization, stemming, lemmatization, and handling imbalanced datasets.
  • Strong understanding of deep learning frameworks like TensorFlow or PyTorch.
  • Hands-on experience with NLP libraries and frameworks such as Hugging Face Transformers, spaCy, NLTK, or similar.
  • Experience with search engine frameworks such as Elasticsearch, Solr, or Lucene.
  • Knowledge of indexing techniques and data structures used in search engines.
  • Experience with query parsing, term weighting, and relevance feedback mechanisms.
  • Familiarity with cloud platforms (AWS, Google Cloud, Azure) for training and deploying LLMs.
  • Excellent problem-solving skills with the ability to innovate and experiment
  • Collaborative mindset with the ability to work effectively in cross-functional teams.
