- Familiarity with CI/CD pipelines, preferably in Azure DevOps.
- Comfortable working with workflow orchestration tools like Airflow.
- Ability to articulate complex technical problems in a clear and simple manner.
- Strong collaboration skills across functional and interdisciplinary teams.
- Confidence to challenge existing practices and propose improvements.
- Relevant experience and fresh perspectives from recent roles.
You'll get extra points for:
- Experience migrating ETL processes to a Java-based backend.
- Knowledge of containerization and how to leverage DTAP environments.
- Familiarity with code style standards and best engineering practices.
- Prior experience in cross-functional teams delivering high-impact solutions.
Your responsibilities:
- Design and build new scalable data processing pipelines using Java.
- Migrate existing data pipelines to a Java-based backend.
- Ensure high data quality through automated testing strategies (unit, integration, system).
- Develop and maintain CI/CD pipelines (using Azure DevOps).
- Apply best engineering practices including containerization, DTAP environments, and code style standards.
- Use workflow orchestration tools like Stonebranch UAC to manage data pipelines.
- Contribute to software design using object-oriented principles and design patterns.
