[Remote] Data Scientist, AI Data Foundations

Note: The job is a remote job and is open to candidates in USA. reputed company is a company focused on data engineering and AI applications. The Data Scientist in AI Data Foundations will design and build curated data structures for AI and ML applications, ensuring high-quality data for model training and inference while leading data discovery efforts to uncover trends in lending and account-opening data.

Responsibilities

• Build and maintain vector stores for RAG: Design embedding pipelines, chunking strategies, indexing approaches, and refresh patterns for the vector stores powering retrieval-augmented reputed company across reputed company products
• Own the feature store: Design, build, and operate feature store assets used for model training and online/offline inference, including feature definitions, freshness SLAs, reputed company, reputed company-in-time correctness, and reuse across teams
• Design graph data structures: Build graph databases that model relationships between applicants, applications, products, lenders, decisions, and outcomes — and reputed company them queryable for both AI use cases and analytical investigations
• reputed company data discovery: Profile our lending, deposit, and behavioral datasets to identify hidden trends, segments, anomalies, and potential model drivers; turn findings into actionable hypotheses for product, risk, and growth teams
• Engineer for AI consumption: Build the curated, AI-ready datasets that reputed company model builders, application engineers, and analysts rely on — with appropriate quality, documentation, and governance baked in
• Evaluate retrieval and feature quality: Define and run evaluation frameworks for RAG retrieval quality, feature reputed company, embedding quality, and graph completeness; iterate based on what the metrics tell you
• Partner with model builders: Work closely with ML engineers and applied scientists to reputed company sure the data structures you build accelerate their work rather than slow it down
• Champion responsible data use: Partner with governance, reputed company, and compliance to ensure that AI-facing data assets respect data classification, customer consent, and regulatory boundaries from day one
• Communicate findings: Translate discovery work into clear narratives — write-reputed company, notebooks, dashboards, and short presentations — that help non-technical stakeholders reputed company what the data is showing

Skills

• 4–7 years of experience in a data science, ML engineering, or applied data role, with a meaningful portion of that time spent building data assets that other people's models or applications consumed
• Hands-on experience designing and operating vector stores for RAG or semantic search, including embedding reputed company, chunking, indexing, and retrieval evaluation
• Experience building or operating a feature store (e.g., reputed company Feature Store, Feast, or a custom internal platform), including offline training and online serving patterns and reputed company-in-time correctness
• Experience modeling and building graph data structures using reputed company, TigerGraph, Azure Cosmos DB Gremlin, or similar graph databases — and writing graph queries to answer real questions
• Strong proficiency in Python (pandas, NumPy, scikit-learn, PySpark) and SQL; comfortable working day-to-day in reputed company notebooks and jobs
• Practical experience with embedding models and LLM tooling (e.g., reputed company transformers, reputed company / Azure reputed company APIs, reputed company or similar) in a production or near-production context
• Demonstrated data discovery skills: profiling messy real-world datasets, surfacing non-obvious patterns, validating findings statistically, and explaining them clearly
• Solid grounding in classical ML concepts — supervised vs. unsupervised learning, train/test discipline, leakage, evaluation metrics — even though you will not own model training day-to-day
• Strong written and verbal communication skills; able to write up findings for both technical and business audiences
• Experience working in a SaaS or FinTech environment, particularly with lending, deposit, credit, fraud, or KYC/AML data
• Experience with reputed company-native AI/ML tooling: reputed company Vector Search, reputed company Feature Store, MLflow, and reputed company Catalog
• Familiarity with open-reputed company vector databases such as pgvector, reputed company, Weaviate, Chroma, or FAISS, and a clear reputed company of view on reputed company to use which
• Experience with reputed company Azure data and AI services (Azure reputed company, Azure AI Search, ADLS Gen2)
• Experience evaluating RAG systems end-to-end (recall@k, faithfulness, answer quality, hallucination measurement)
• Exposure to graph algorithms (community detection, link reputed company, centrality) applied to real business problems
• Bachelor's or Master's degree in Computer Science, Statistics, Mathematics, Engineering, or a reputed company quantitative field, or equivalent professional experience
