Senior Data Engineer (230009AA) (вакансія неактивна)

Київ, Львів, Дніпро, Вінниця, віддалено

Ciklum is looking for a Senior Data Engineer to join our team full-time in Ukraine.

We are a leading global product engineering and digital services company that unites 4000+ seasoned professionals globally on various projects in healthcare, fintech, travel, sportswear, entertainment, and security. Ciklum delivers high-impact technology solutions to Fortune 500 and fast-growing organisations worldwide.

About the role:

As a Senior Data Engineer, become a part of a cross-functional development team working for our Client.

About the project:

This is a migration project from client’s data platform from Cloudera (On premises) to Databricks (Azure). Among the things to be migrated they have many PySpark scripts that read data from relational databases and save the processed data to Hive, Impala, Kudu and Solr.

There are also some NiFi workflows that read different files from many sources and persist them into the data lake, which is built on top of HDFS (inside Cloudera stack). These workflows need to be migrated as well.

There is a third processing engine in Python that also reads data from different sources and saves the results to the data lake (Hive, HDFS, KUDU).They will use ADLS gen2 as their data lake and the processing will be done in spark inside the Databricks stack.
Currently the job coordination is done using NiFi and Oozie, but the client wants to migrate to either Databricks workflows with Azure Data Factory or Airflow (hosted on Azure and offered as a service). This last point is still open.

The use cases are all related to analytics of payment data and many operational reports that the payment ecosystem and the different clients need.
