What to look for in a Apache Spark freelancer
A capable Spark engineer optimizes for both correctness and cost per run. Look for:
- A grasp of how Spark actually executes: partitions, shuffles, and the DAG.
- Experience debugging skew and spills, the reasons jobs get slow and expensive.
- Comfort with your platform: Databricks, EMR, or a self-managed cluster.
- Solid data engineering habits: idempotent jobs, tests, and clear schemas.
- Cost awareness, because compute time is real money at scale.
Ask about a job they made faster or cheaper, and what they changed.
