About

We are seeking a skilled Senior Data Engineer / Data Scientist to join our client's team.
We are seeking highly skilled Data Engineers and Data Scientists to strengthen Data Mastering and Entity Resolution capabilities within our client's platform. The ideal candidate will possess deep expertise in semantic matching, data normalization, entity resolution, and large-scale data processing. This role is critical in enhancing mastering accuracy across data ingestion, matching, merging, and rollup processes while ensuring scalability and data quality across enterprise platforms.
Data Mastering & Entity Resolution
Design, develop, and optimize data mastering frameworks and entity resolution solutions.
Improve matching accuracy across ingestion, merge, and rollup layers using advanced algorithms and AI/ML techniques.
Build and enhance semantic matching capabilities for structured and unstructured data sources.
Develop strategies for data standardization, normalization, deduplication, and golden record creation.
Leverage machine learning, NLP, embeddings, and AI-based approaches to improve semantic matching and record linkage.
Develop and deploy models for entity identification, clustering, similarity scoring, and data quality enhancement.
Evaluate and optimize model performance using precision, recall, F1-score, and other relevant metrics.
Design and build scalable, production-grade data pipelines for processing large volumes of data.
Implement data ingestion, transformation, validation, and mastering workflows.
Ensure data quality, governance, lineage, and observability across the platform.
Collaborate with engineering teams to operationalize AI/ML models within production environments.
Cross-Functional Collaboration
Work closely with product, engineering, architecture, and business teams to define mastering requirements and success metrics.
Drive continuous improvements in data quality, matching accuracy, and platform scalability.
Contribute to technical design reviews, architecture discussions, and best practices.
