- Build data pipelines using PySpark, Apache Beam or similar frameworks; integrate with streaming platforms (Kafka, Pulsar) and batch ingestion layers.

- Collaborate with data-science teams to package, serve and monitor ML models for anomaly detection, transaction clustering and network analysis.

- Implement data-quality, lineage and privacy controls (GDPR/CCPA) throughout ingestion-to-case-management flows.

- Implement end to end data orchestration with proper data modeling.

- Document architectural decisions, API contracts and data-flow diagrams to keep the AML platform aligned with the target-state design.

Tech Stack & Requirements :

- Expert-level knowledge on Python, async programming, libraries : FastAPI/Django/Flask, Celery, Pandas, NumPy, PySpark.

- Experience in designing, developing and securing REST/GraphQL services; event-driven patterns (Kafka, Pulsar).

- Experience in building/optimizing ETL/ELT pipelines; experience with Spark/Flink.
