This role is vital for designing real-time and batch data pipelines used in fraud detection reconciliation and regulatory reporting. If youre an expert in streaming technologies cloud data architecture and high-volume transaction processing this is your opportunity to work on cutting-edge systems at global scale.
What you get to do::
Issuer Processing Data Engineering
- Design and build pipelines for end-to-end card transaction event processing (authorization through settlement).
- Normalize and process ISO8583/JSON payloads including de-duplication and correlation of retries reversals and late-clearing messages.
- Develop frameworks for scheme fee computation network clearing reconciliation and settlement reporting.
- Build client-level reporting capabilities for operational and audit purposes.
- Collaborate with Risk Fraud and Compliance teams to integrate real-time analytics and scoring mechanisms.
Data Architecture & Platform Engineering
- Design and implement both streaming and batch data pipelines using Kafka Flink Spark and Dataflow.
- Manage schema evolution and contract validation for changing transaction formats.
- Build and maintain data lakehouse environments (e.g. Delta Lake Iceberg).
- Enable performant OLAP workloads using BigQuery Redshift or Snowflake through appropriate data modeling strategies.
- Develop ETL/ELT orchestration with tools like Airflow Dagster or dbt.
- Implement observability lineage tracking and data quality monitoring using tools like Great Expectations and Monte Carlo.
What you can look forward to::
At Paymentology it s not just about building great payment technology it s about building a company where people feel they belong and their work matters.
