Senior Data Engineer – Rewards Platform and Data Analysis- София

Описание

General duties
Build the real-time core

Design, build and run real-time Python pipelines that consume events from Kafka and apply campaign rules: customer eligibility, reward caps and frequency limits.
Own the progress store and points ledger in PostgreSQL, the CDC streams around them, and the second stage that grants rewards and sends notifications to DSK Mobile.
Make every reward correct by design: idempotent processing, full traceability back to the transaction that earned it, and clean handling of reversals and refunds.
Keep the numbers right

Build the reconciliation process against our golden source, the transaction tables in DWH / Databricks
Develop batch processes in Databricks, dbt and Apache Airflow: daily customer eligibility, aggregates and history.
Monitor latency, errors and lost events, set up alerting and resolve incidents.
Make campaigns fast to launch

Turn new campaigns into configuration and grow a library of reward mechanics – capped cashback, monthly challenges, boosted partner cashback – so the program team can launch without new code.
Plug new data sources into the engine and maintain the engagement and reward catalogs.
Power the business

Prepare data models and logs for Power BI reporting, campaign performance analysis, complaint handling, and partner invoicing and commissions.
Write tests and technical documentation for every pipeline and configuration.
Help shape the rewards platform architecture and technology choices.
