Data Scientist AI

We are looking for a hands-on Data Scientist specializing in Natural Language Processing to design, build, evaluate, and deploy production-grade NLP and machine-learning solutions for complex text-driven workflows. Core Responsibilities • Design and build NLP and machine-learning pipelines that transform noisy, heterogeneous text data into clean semantic layers ready for modeling, retrieval, analytics, and downstream product use. • Develop retrieval systems for semantic search, candidate ranking, out-of-vocabulary handling, and high-quality information discovery using embeddings and vector search. • Build, compare, and evaluate supervised and hybrid approaches, including multioutput classifiers, hierarchical classifiers, NER-style parsers, clustering techniques, and rule-plus-ML systems. • Analyze decision boundaries and relationships across free-text fields using conditional distributions, entropy, mutual information, directional association, embeddings, and predictive ablation studies. • Deploy, monitor, and continuously improve ML services in collaboration with platform, backend, data engineering, and product teams. Required Skills • Strong Python and SQL skills, with hands-on experience building production data pipelines and machine-learning workflows. • Practical experience with text classification, semantic similarity, embeddings, information retrieval, ranking, clustering, or entity extraction. • Experience with Hugging Face, SentenceTransformers, tokenization, fine-tuning, transformer-based models, and model evaluation. • Solid understanding of vector search, cosine similarity, approximate nearest-neighbor methods, and retrieval metrics such as Recall@K, MRR, and NDCG. • Ability to design experiments, define evaluation metrics, compare model trade-offs, and communicate findings clearly to technical and non-technical stakeholders.

Nice to Haves • Experience with healthcare, imaging, enterprise metadata, document intelligence, search, recommendation, knowledge retrieval, or routing systems. • Knowledge of DICOM, PACS/RIS, HL7/FHIR, or other structured-plus-free-text enterprise data standards. • Familiarity with MLOps, cloud deployment, API-based model serving, monitoring, responsible AI practices, or privacy-aware handling of sensitive text data.
