Senior Data Engineer - Athens, Hybrid (3-2)

Our client is the analytics arm of a listed Greek retail group building a group-wide data platform to serve 20+ internal product teams. The role exists because the current Hadoop-based stack is being replaced with a modern lakehouse architecture and needs an experienced engineer to own the transition.

The Role

You will design and build the core ingestion, transformation and orchestration layers on Databricks, migrating batch ETL jobs from legacy pipelines and onboarding new real-time data sources. Your first six-month milestone is delivering a production-ready Delta Lake platform with four critical data domains live. You will also mentor one junior data engineer and help establish the engineering standards the wider team builds on.

What You'll Bring

• 5+ years in data engineering or big-data engineering roles
• Hands-on experience with Apache Spark using PySpark or Scala
• Production experience with Databricks including Delta Lake and Unity Catalog
• Strong SQL and data modelling skills across dimensional, data vault or medallion architecture
• Experience with orchestration tools such as Apache Airflow, Prefect or Dagster

Nice to Have

• Experience with streaming pipelines using Kafka or Spark Structured Streaming
• Familiarity with dbt for transformations
• Azure or AWS cloud data services experience across ADLS, Glue or Redshift

What's in it for You

€4,500-5,800 monthly gross, depending on experience and technical background. Hybrid working in Athens, 3 days in office and 2 from home. Private health insurance and an annual learning budget to keep your skills sharp as the platform evolves
