About the Role

Job Title: Big Data Engineer

Experience: 5-8 years

We are looking for a Data Engineer with in-depth experience in working with Cloudera, Informatica, and Alteryx to design, implement, and manage robust data engineering solutions. In this technical role, you will work with large-scale data processing systems, build high-performance ETL pipelines, and ensure the smooth integration of data from multiple sources. This position requires proficiency in big data technologies, data integration platforms, and automation tools, along with a strong ability to optimize workflows for performance and scalability.

Key Responsibilities:

1.Design, implement, and optimize data pipelines for batch and real-time data processing using Cloudera (Hadoop, Hive, Spark, Impala) and Informatica (PowerCenter, Cloud Data Integration).

2.Build data extraction, transformation, and loading (ETL) workflows using Informatica PowerCenter for large-scale data integration from source systems (e.g., relational databases, flat files, APIs) into Cloudera Data Lake or data warehouse environments.

3.Implement Spark jobs on Cloudera for distributed data processing and optimization of data workflows.

4.Leverage Informatica for orchestrating ETL workflows, including data extraction, cleansing, transformation, and loading into data repositories (HDFS, Hive, SQL databases, etc.).

5.Create Alteryx workflows to automate data preparation, cleansing, and transformation, making data available for downstream analysis or reporting.

6.Leverage Alteryx's native connectors to integrate with external data sources (e.g., SQL databases, APIs, cloud services).

7.Optimize the Informatica and Alteryx workflows to minimize runtime, ensure smooth data integration, and maintain high data quality.

8.Utilize Hadoop and Spark on Cloudera to process large datasets and implement data transformations using MapReduce, Spark SQL, and PySpark.

9.Leverage Impala for low-latency SQL queries on Hadoop, ensuring real-time access to processed data.

10.Implement partitioning, bucketing, and indexing strategies in Hive and HBase to improve query performance on large datasets.

11.Implement and enforce data quality rules within Informatica and Alteryx workflows, ensuring that all transformations meet the required standards for completeness, consistency, and accuracy.

12.Ensure compliance with data governance and security protocols (e.g., encryption, masking, access control) in accordance with industry best practices.

13.Automation and Scheduling: Automate ETL workflows using Informatica and Alteryx Server, integrating with Airflow, Nifi or other workflow orchestration tools for scheduling and monitoring jobs.

14.Utilize Cloudera Navigator for monitoring and auditing data processes within the Hadoop ecosystem.

15.Perform regular tuning of the ETL pipelines, data flows, and SQL queries to ensure optimal performance.

Required Qualifications:

1.Education: Major in Computer Science or related field.

2.Years of experience: 5 - 8

3.Cloudera Platform Experience: Proven experience with the Cloudera Distribution of Hadoop (CDH), including expertise in HDFS, Hive, Impala, Spark, and HBase.

4.Informatica Expertise: Strong hands-on experience with Informatica PowerCenter (ETL), EDC, IDQ, B2B, and Axon.

5.Alteryx Expertise: Proficiency in developing and automating data workflows using Alteryx Designer and Alteryx Server for end-to-end data transformation, integration, and reporting automation.

6.Big Data & ETL Knowledge: Deep understanding of ETL best practices, data pipelines, and distributed computing technologies such as Spark, MapReduce, PySpark, and Hadoop ecosystem components.

7.SQL Proficiency: Advanced SQL skills for data manipulation, aggregation, optimization, and reporting across relational and non-relational data stores (e.g., SQL Server, MySQL, PostgreSQL, Hive, Impala).

8.Programming Skills: Experience in Python and SQL.

9.Data Warehousing: Strong background in data warehousing principles and data modeling, including dimensional modeling (star schema, snowflake schema) and OLAP/OLTP considerations.

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
