Reduced cloud costs by optimizing Spark jobs.
Spearheaded a compute optimization initiative for Spark clusters, reducing monthly cloud infrastructure spend by $840K while maintaining processing latency.
Managed Airflow DAGs for data pipelines.
Spearheaded the migration of 12 critical Airflow DAGs to a containerized Kubernetes executor, increasing pipeline uptime from 98.2% to 99.9%.
Fixed bugs in SQL queries to save money.
Optimized complex SQL transformations in dbt, decreasing monthly cloud compute costs by $12K while maintaining data integrity.
What hiring managers want
- Pipeline Reliability: expected at all levels
- Architectural Ownership: mid to senior
- Technical Strategy: staff and above
Common mistakes to avoid
- All levels: Listing technologies like Airflow or Snowflake without explaining specific production application
- Junior/Mid: Focusing on script writing rather than pipeline scalability or data integrity impact
- Senior/Staff: Missing evidence of mentorship or how architectural choices solved business-wide bottlenecks
Common questions
Which Data Engineer resume example matches my experience?
Select the junior example if you focus on building individual pipelines and learning core tools. Choose mid or senior if you own entire systems or mentor others, and staff if you define the organization's technical roadmap.
What skills should I highlight as a Data Engineer?
Focus on core execution skills like Python and SQL alongside orchestration tools like Airflow and cloud warehouses like Snowflake or BigQuery. For senior roles, emphasize distributed processing with Spark or Kafka.
How do I quantify my impact as a Data Engineer?
Use metrics that reflect system efficiency, such as reducing pipeline latency by a specific time unit or lowering monthly cloud infrastructure costs. You can also mention the scale of data handled, such as events per day or total users supported.
Should I include data science or machine learning skills on my resume?
Only include these if they directly relate to the data engineering work you performed, such as building a feature store or deploying model pipelines. Hiring managers prioritize your ability to build stable infrastructure over your ability to build models.
How long should my Data Engineer resume be?
Junior and mid-level engineers should stick to a concise one-page resume focusing on technical projects. Senior and staff engineers may extend to two pages to capture complex architectural designs and cross-team leadership impact.
