Data Engineer
Sample Resume & ATS Keywords
Data engineering is a distinct discipline from data science, and because no government agency publishes a standalone occupation code for it, recruiter search runs almost entirely on pipeline and warehouse tooling keywords rather than job-title history. A resume that says "built data pipelines" without naming Airflow, dbt, or the warehouse platform won't surface — the example below shows the keyword-complete version.
All sample resume content on this page is original and illustrative — fictional candidates, realistic numbers. Use it as a pattern, not a template to copy verbatim.
Sample Data Engineer resume summary
What a parseable, keyword-complete professional summary looks like for this role:
Data Engineer with 5 years building and maintaining pipelines for a retail analytics platform processing 200M+ events daily. Owns orchestration (Airflow), transformation (dbt), and streaming ingestion (Kafka, Spark) feeding a Snowflake warehouse used by 80+ analysts. Enforces data-quality checks and SLAs on 40+ production pipelines and maintains full lineage documentation for audit and debugging.
Sample achievement bullets that pass ATS screening
Each bullet follows the pattern recruiters and parsers reward: exact keywords, a specific action, and a quantified outcome.
- Built and maintained 40+ Airflow DAGs orchestrating ingestion and transformation for 200M+ daily events, holding a 99.5% on-time SLA over the trailing 12 months.
- Migrated a legacy batch ETL process to a Kafka-based streaming pipeline, cutting data latency from 4 hours to under 5 minutes for real-time inventory dashboards.
- Modeled the core Snowflake warehouse schema and dbt transformation layer serving 80+ analysts, cutting average query time 45% through partitioning and clustering changes.
- Implemented automated data-quality checks (Great Expectations) across 25 critical tables, catching 14 upstream data issues before they reached downstream dashboards.
- Built end-to-end lineage documentation (dbt docs) for the warehouse, cutting new-analyst onboarding time from 2 weeks to 3 days.
- Optimized a Spark job processing 1.2TB of daily clickstream data, reducing cluster runtime 38% and cutting monthly compute cost by $9,000.
- Led the migration of 15 legacy Redshift tables to Databricks/Delta Lake, enabling incremental processing that cut nightly batch runtime from 5 hours to 90 minutes.
- Partnered with the ML engineering team to build a shared feature-store pipeline, reducing duplicate data-transformation work across 3 teams.

Data Engineer resume formatting: do this, not that
Do
- Name pipeline and orchestration tools exactly: Airflow, dbt, Spark, Kafka — recruiters search these as specific strings.
- Name the warehouse or lakehouse platform: Snowflake, BigQuery, Databricks, Redshift.
- Use data-modeling and quality vocabulary directly: schema design, data quality, SLAs, lineage.
- Quantify pipeline outcomes: data volume processed, latency reduced, pipelines maintained, uptime/SLA held.
- Show ownership of the full path — ingestion, transformation, warehouse — not just one stage.
Don't
- Don't write "built data pipelines" without naming the orchestration tool and data volume.
- Don't blur data-engineering and data-science vocabulary — they're separate hiring pools searched differently.
- Don't omit data-quality practices — "reliable data" without a check or SLA reads as unverified.
- Don't leave out the warehouse platform — it's one of the most-searched terms in this discipline.
- Don't understate scale — daily event volume and table count calibrate seniority for recruiters scanning quickly.
