Original job description

Cognizant (NASDAQ: CTSH) is a leading provider of information technology, consulting, and business process outsourcing services, dedicated to helping the world's leading companies build stronger businesses. Headquartered in Teaneck, New Jersey (U.S.). Cognizant is a member of the NASDAQ-100, the S&P 500, the Forbes Global 1000, and the Fortune 500 and we are among the top performing and fastest growing companies in the world.

ML/AI Data Scientist

Role Summary

Build the matching, inference, and labeling models that resolve entities into golden records and bring Gemini-assisted intelligence into the ontology.

Key Responsibilities

Own entity matching and bridging: design and build fuzzy and exact matching models to stitch duplicate entities into golden records.
Build inference models to support data profiling - identifying patterns, relationships, and anomalies in profiled source data.
Support the business-ontology effort with Gemini-assisted labeling models that classify records into business domains (Location, Asset, Service, Event, Work-ticket).
Design and build labeling workflows combining weak supervision, LLM-assisted labeling, and human-in-the-loop review.
Deploy and manage matching, inference, and labeling models on Vertex AI.
Evaluate model performance (precision/recall, drift) and work with the Architect and Data Domain SME to validate outputs against ontology rules.
Partner with the Backend/Agent Engineer to expose matching/labeling models as callable tools within the agent orchestration layer.
Continuously retrain and tune models as new source data and golden-record feedback become available.
Document model logic, training data lineage, and known limitations for each deployed model.
Support QA in defining acceptance thresholds for model-driven outputs (matching accuracy, labeling precision).

Core Skills

Entity resolution / matching: fuzzy and exact matching techniques for golden-record creation.
Inference and pattern-detection modeling over profiled data.
LLM-assisted labeling and classification (Gemini) with human-in-the-loop review design.
Model deployment, evaluation, and drift monitoring on Vertex AI.
Weak supervision and semi-supervised labeling workflow design.

Required Qualifications

5+ years in applied ML, including entity resolution, classification, or NLP-based matching.
Strong Python; experience with PyTorch and/or scikit-learn.
Hands-on experience deploying and evaluating models on Vertex AI.
Experience with embeddings, LLMs, or NLP techniques for matching and classification.
Experience designing labeling workflows (weak supervision, LLM-assisted, human-in-the-loop).

Preferred Qualifications

Experience with knowledge graphs or ontology-aligned ML (feature use over graph data).
MLOps experience (model versioning, monitoring, retraining pipelines).
GCP ML Engineer certification.

Tools & Technologies

Vertex AI, Gemini APIs, Python, PyTorch, scikit-learn, BigQuery, Spanner Graph or equivalent graph platform (for feature/context retrieval)
