Build data pipelines for ingestion, cleaning, labeling, and feature engineering, including entity resolution and relationship extraction where needed
Develop and validate statistical/ML models (risk scoring, anomaly detection, fraud patterns, forecasting, classification)
Create event-driven analytics using strong time semantics (event ordering, windows, causality assumptions, lifecycle states)
Partner with engineering to productionize models: batch + near-real-time scoring, monitoring, drift checks, and reproducible experiments
Communicate findings clearly via notebooks, dashboards, and concise writeups
Qualification
Required
Strong foundation in statistics + machine learning (evaluation, leakage prevention, bias checks, calibration, experimentation)

Querying: Cypher (Neo4j) and/or Gremlin/SPARQL
Graph algorithms: PageRank, betweenness, connected components, community detection, similarity
Strong Python for DS (pandas, numpy, scikit-learn; comfort writing production-ready code)
Solid data engineering basics: SQL, ETL, data quality checks, versioning, reproducibility
Ability to explain technical results to non-technical stakeholders
