Dockerfile Data Validation Engineer

The work

You will build and maintain validation workflows inside Docker-based build pipelines used to support AI systems. Your work will help check datasets, schemas, and model artifacts before deployment.

The role combines container configuration, metadata standards, scripting, and automated quality checks. You will work across data engineering, machine learning, and DevOps workflows.

• Develop and improve Dockerfiles with built-in data-validation steps.
