Hybrid: Westlake, TX
Our client, a leader in their industry, has an excellent opportunity for a Data Engineer to work in a contract position in Westlake, TX or Merrimack, NH. This position is hybrid onsite for two weeks a month and candidates must be local to the metro area.
This Data Engineer role is not your typical ETL developer role, it’s a strategic, hands-on engineering position where you'll play a direct role in building a brand-new internal ETL tool using open-source technology to replace costly legacy solutions like Informatica.
Due to client requirement, applicants must be willing and able to work on a w2 basis. For our w2 consultants, we offer a great benefits package that includes Medical, Dental, and Vision benefits, 401k with company matching, and life insurance.
Responsibilities:
· Design, develop, and maintain robust data pipelines to support ETL/ELT use cases
· Implement and optimize workflows using Apache Hop, Apache BEAM, NiFi, Spark, and Airflow
· Deploy and manage containerized applications in a Kubernetes-based cloud environment
· Utilize Python and Java for API integration and data engineering solutions
· Apply Infrastructure-as-Code practices using tools like Terraform, CFT, or ARM
Experience Requirements:
· 10+ years of professional IT experience in data engineering related roles
· Hands-on experience with Apache tools like Hop, BEAM, NiFi, Spark, and Airflow
· Strong proficiency in Python and Java for API connection work (must-have)
· Strong background in cloud platforms such as AWS or Azure.
· ETL tool expertise including Informatica, Python, or DBT (with preference for open-source tools)
· Infrastructure-as-Code practices using tools like Terraform, CloudFormation, or ARM
· Kubernetes – ability to containarize and deploy an ETL job to the cloud
Preferred:
· Certification in Azure or AWS cloud platforms
· Skilled in CI/CD pipelines using GitHub, Jenkins, and Artifact
· Experience with Snaplogic or Informatica for data integration
· Monitoring and alert configuration experience for high-availability environments
· Familiarity with marketing data sets or customer data platforms
· Effective communicator and problem solver in agile, fast-paced teams
Education Requirements:
Bachelors Degree Required
W2 employees of Eliassen Group who are regularly scheduled to work 30 or more hours per week are eligible for the following benefits: medical (choice of 3 plans), dental, vision, pre-tax accounts, other voluntary benefits including life and disability insurance, 401(k) with match, and sick time if required by law in the worked-in state/locality.
