Professional Summary
Big Data Engineer with 7+ years of experience designing and operating petabyte-scale distributed data systems. Expert in Apache Spark, Hadoop, and Kafka with deep knowledge of cluster tuning, data partitioning, and cost optimization. Managed infrastructure processing 20PB+ of data and reduced compute costs by $800K annually.
Experience
- •Managed and optimized a 2,000-node Hadoop/Spark cluster processing 20PB+ of member activity, job listing, and messaging data across 3 data centers.
- •Redesigned the data partitioning strategy for the largest Hive tables, reducing storage footprint by 40% and improving query performance by 55%.
- •Built a Spark Structured Streaming pipeline ingesting 5M+ events per second from Kafka for real-time feed ranking and notification systems.
- •Developed a cost attribution framework that tracked compute usage per team, enabling data-driven infrastructure budgeting and saving $800K annually.
- •Built and maintained Apache Spark and Hive pipelines processing 5TB+ of daily ad impression and click-stream data for advertising analytics.
- •Implemented a data compaction service using Spark that merged small files on HDFS, reducing NameNode memory pressure by 30% and improving job scheduling.
- •Contributed to the open-source Apache Spark project by fixing 3 critical bugs in the Catalyst optimizer, merged into Spark 3.3 release.

How to Write a Big Data Engineer Resume
Professional Summary
Lead with the scale of data you have worked with (PB, TB/day, events/second). Mention cluster sizes and cost optimization outcomes.
Work Experience
Quantify everything: cluster sizes, data volumes, event throughput, cost savings, and performance improvements. Show deep expertise in distributed systems tuning.
Skills Section
List big data frameworks (Spark, Hadoop, Kafka), query engines (Presto, Hive), and cloud platforms. Include Scala/Java alongside Python.

Not differentiating from a generic Data Engineer.
Emphasize petabyte-scale, cluster management, distributed systems tuning, and low-level optimization—this is what sets big data engineers apart.
Listing Hadoop without specifying components.
Be specific: HDFS, YARN, Hive, MapReduce, HBase. "Hadoop ecosystem" is too vague.
Ignoring cost optimization.
At big data scale, cost is a primary concern. Mention compute/storage cost reductions and resource utilization improvements.
Not mentioning streaming alongside batch.
Modern big data roles require both batch and streaming expertise. Highlight Kafka, Flink, or Spark Structured Streaming.
Big Data Engineer Resume FAQs
Is Hadoop still relevant in 2026?
Hadoop on-premise is declining, but its ecosystem (Hive, HDFS concepts, YARN) underpins many cloud services. Companies like LinkedIn, Yahoo, and Meta still run massive Hadoop clusters.
Should I learn Scala or Python for big data?
Both. Python (PySpark) is more common, but Scala offers better Spark performance and is valued at companies with large JVM-based infrastructure.
How do I demonstrate "big data" experience?
Quantify data volumes (TB/PB), cluster sizes (node counts), event throughput (events/second), and processing windows (batch runtime).
What cloud skills should a Big Data Engineer have?
AWS EMR, Databricks, GCP Dataproc, or Azure HDInsight. Understanding cloud-native alternatives to on-prem Hadoop is essential for career growth.
