We are now looking for a Data Engineer to improve our data processing pipelines from performance, cost and correctness standpoints.
You could be a perfect match for the position if

You want to:

• Migrate BigQuery workloads to Spark 3.5 on Databricks.
  Re-engineer our daily-TB batch jobs into Delta Lake pipelines that run faster and cost less.
• Turn full reloads into true incremental processing.
  Build CDC / MERGE logic so we scan only the data that changed and deliver fresh features within minutes.
• Add quality gates & observability from day one.
  Instrument every stage with custom metrics, data-drift alerts and cost reports the product team can read.
• Set up monitoring & slot-second cost dashboards.
  Expose processing-time, SLA and $-per-feature charts so we can make data-driven trade-offs.
• Pair with Data Scientists and Product Managers. 
  Work side-by-side with Data Scientists and Product Managers from idea to release, instead of simply passing datasets back and forth.
• Continuously tune for scale.
  Dozens of terabytes move through the platform daily; you’ll experiment with partitioning, Z-ORDER, and Photon to keep latency low as volume grows.

You have: 

• 3+ years of experience in data engineer role.
• Strong knowledge of SQL, Spark, Python, Airflow, binary file formats. 
• English level - Upper-intermediate +.

Pleasant extras:
