Data Scientist

Designs and implements Natural Language Processing (NLP) pipelines for preprocessing and analyzing “noisy” or incomplete text data.
Utilizes embeddings (e.g., word, sentence, multilingual) for semantic similarity and feature engineering in record linkage workflows.
Updates NLP models for domain-specific tasks, such as abbreviation recognition and title normalization.
Develops and trains machine learning models for match / no-match classification.
Optimizes hyperparameters and enhance model performance.
Deploys NLP and Machine Learning (ML) models into batch and streaming pipeline using Databricks.
Manages model lifecycle, including versioning, deployment and monitoring.
Implements monitoring solutions to detect model drift and continuously refine solutions based on real-world performance.
Collaborates with Data Analysts to extract actionable insights from datasets, including text data.
Collaborates with Data Engineers to integrate NLP and ML models into scalable Extract, Transform, Load (ETL) pipelines.
Partners with stakeholders to align technical solutions with business needs.
Explores cutting edge NLP approaches, such as transformer-based models, for improving text matching.
Evaluates new tools and frameworks, including vector databases, to enhance the AI / ML pipeline.
Researches multilingual and cross-lingual NLP solutions for entity resolution.
Regular attendance.
Other duties as assigned.
