What should a data engineer put on their resume?
Focus on three pillars: (1) Infrastructure tools with specifics (Spark, Airflow, Kafka, Snowflake, not just 'data tools'), (2) Scale and reliability metrics ('processing 12TB+ daily at 99.9% SLA', not 'handled large datasets'), and (3) Cost and time savings ('reduced compute costs by 60%, saving $800K per year', not 'improved efficiency'). In 2026, ATS systems scan for Spark, Airflow, Kafka, Snowflake, dbt, AWS, ETL, and SQL. Over 90% of data engineer job descriptions include these terms. Not sure which ones you are missing?

How do I write a data engineer resume with no experience?
Use this formula for projects: [Action Verb] + [What You Built] + [Tools Used] + [Scale] + [Quantifiable Result]. Example: 'Built an ETL pipeline using Airflow and dbt to ingest 5GB of daily weather data into Snowflake, enabling automated daily reporting for 3 research teams.' Personal projects, hackathons, open-source contributions, and university capstones all count. The AWS Data Analytics Specialty or Databricks Data Engineer Associate certification also signals production readiness. Education goes above experience when you have less than 2 years of work history.
What are the best ATS keywords for a data engineer resume in 2026?
The most impactful keywords fall into five categories: Batch Processing (Spark, PySpark, Hadoop, Databricks, EMR), Orchestration (Airflow, dbt, Prefect, Dagster), Streaming (Kafka, Flink, Kinesis, Spark Streaming), Warehousing (Snowflake, BigQuery, Redshift, Delta Lake), and Infrastructure (AWS, GCP, Terraform, Docker, Kubernetes, CI/CD). In 2026, dbt, Snowflake, and streaming technologies are increasingly appearing in job descriptions. Upload your resume to see exactly which keywords you are missing.
What is the difference between a data engineer and data scientist resume?
Data engineer resumes emphasize infrastructure, reliability, and scale: Spark, Airflow, Kafka, Snowflake, ETL/ELT, data modeling, and SLA uptime. Data scientist resumes emphasize models, accuracy, and business outcomes: TensorFlow, PyTorch, Scikit-learn, A/B testing, and model deployment. If you are transitioning between the two, highlight overlapping skills (Python, SQL, cloud platforms) and tailor your bullet points to the target role. ATS filters are specific to the role title, so using the wrong keywords means your application never reaches a human.
What ATS systems do US data engineer employers use?
US data infrastructure hiring clusters on three platforms. Workday is the default at enterprise and Fortune 500 data orgs, where it parses tool tokens against the requisition's required-skills array. Greenhouse dominates Series B to D SaaS startups and modern data stack vendors, weighting verb plus throughput pairs in its keyword indexer. Lever is common at Series A to C startups and developer-tooling companies. All three parse plain text bullets cleanly; all three mishandle pipeline architecture diagrams as image bullets, multi-line 'Tech Stack' headers, and dollar signs adjacent to compute-cost figures. Single-column plain text with tool names as flat lists and numerals on the verb line clears every parser.
What's a passing ATS score for a data engineer resume?
There is no industry standard cutoff, but recruiter screens at most US data orgs ignore resumes scoring below roughly 70 on internal Greenhouse or Workday match scores; senior data engineer reqs often filter at 80 or above because the keyword surface (Spark, Airflow, Snowflake, throughput, SLA, cost reduction) is well defined. Resumes scoring 85 to 95 reliably reach the hiring manager shortlist. The published ATS pass-rate distribution and the data behind these benchmarks are in the ResumeAdapter ATS Statistics report at /ats-statistics.

How many years of experience do I need to become a data engineer?
US hiring follows a clear ladder visible in the seniority examples on this page. Entry level and new grad roles need 0 to 2 years and emphasize SQL optimization, data cleaning, and report automation, often paired with one cloud certification. Mid level data engineer roles need 2 to 5 years with full ETL ownership, dbt or Airflow proficiency, and A/B test plumbing experience. Senior data engineer roles need 5 to 10 years with platform design, cost optimization, and on-call ownership. Head of Data Engineering and VP Data roles need 10+ years with multi-team budget ownership and governance experience across business units.
How do I quantify data engineer achievements without numbers?
Never fabricate metrics; ATS parsers do not care, but technical screens and reference checks will expose invented throughput, latency, or cost figures. If precise numbers are not available, use directional and structural framing: 'designed the ingestion layer that replaced the prior batch script', 'cut nightly job runtime from overnight to under an hour', or 'rebuilt the dbt project that became the standard across the data team'. Pull approximate ranges only from materials you can defend (architecture decision records, runbooks, on-call dashboards). For older roles, ask former platform leads or check Datadog or Grafana exports before applying. Directional honesty beats invented precision on every technical screen.
