• Build and maintain batch and streaming data pipelines using Python, SQL, Kafka, and Spark.
• Develop and operate Airflow workflows, including scheduling, dependency management, retries, and recovery.
• Design and maintain data models and warehouse datasets for analytics and reporting.
• Improve data quality and freshness through validation, monitoring, and investigation of upstream and downstream issues.
• Optimise pipeline and query performance, and manage processing and storage costs.
• Work with data users to define datasets and metrics, and document data flows, transformations, and dependencies.

What you’ll bring

• Data engineering experience within crypto or Web3, including responsibility for production pipelines or a data platform.
• Strong Python and SQL skills, with experience building maintainable data processing workflows.
• Hands‑on experience with Airflow, Kafka, and Spark.

• BI experience, including supporting dashboards, defining metrics, or preparing datasets for business users.
• Strong English communication skills.
