What does a Data Engineer do?

A data engineer designs, builds and maintains the systems that move, transform and deliver reliable data. They work with pipelines, storage, orchestration and monitoring so analysts, applications and AI workloads can use trustworthy data. Responsibilities vary across cloud platforms and organizations.

01

Data ingestion & integration

Connect APIs, databases, files and streams to ingest structured and unstructured data reliably.

02

SQL, Python & PySpark

Write queries and transformations, process large datasets and maintain reusable data processing code.

03

ETL/ELT & orchestration

Build batch and streaming pipelines with dependency handling, scheduling, logging and retries.

04

Lakehouses & warehouses

Model storage layers and choose appropriate analytical data stores for performance and governance.

05

Quality, security & governance

Validate datasets, manage access and lineage, and apply controls to sensitive information.

06

Monitoring & optimization

Detect failed jobs, diagnose data freshness issues and balance throughput, reliability and cost.

Data Engineer vs. Business Analyst

Data engineers build and maintain pipelines that make reliable data available. Business analysts define problems, requirements and success measures for decisions and business change. Data analysts then frequently use that data to create insights. Explore Business Analyst.

Data Engineer vs. Solutions Architect

Data engineers build, operate and optimize data processing systems. Solutions architects focus more broadly on selecting system designs, trade-offs and integrations across business and technology requirements. Explore Solutions Architect.

Your data engineering career path

How to become a Data Engineer

There is no mandatory sequence. Start with SQL and programming fundamentals, build real pipelines, get hands-on with cloud data platforms and choose a certification aligned with your experience and target role.

01

Develop SQL and programming skills

Learn relational concepts, joins, transformations, Python and version control. Understand the difference between analytical and transactional workloads.

Start with SQL, Python and data fundamentals
02

Build a complete data pipeline

Create a portfolio project that ingests raw data, validates quality, transforms it and stores it for repeatable queries and reporting.

Show ETL/ELT, tests, logging and documentation
03

Scale into cloud and distributed data

Explore data warehouses, lakehouses, orchestration, Spark, access controls and monitoring for batch or streaming workloads.

Practice on Microsoft Fabric, Databricks or cloud labs
04

Validate the right specialization

Choose DP-700 for Fabric data engineering, an Apache Spark credential for processing skills or foundational exams if you are just starting out.

Use labs and a targeted MeasureUp Practice Test

View practice test
Choose by target workload. DP-700 is the strongest direct fit for Microsoft Fabric data engineers. DP-900 provides fundamentals, Databricks DCAD focuses on Apache Spark, and DP-600 is an adjacent analytics engineering track. Google Cloud Database Engineer and Associate Cloud Engineer strengthen neighboring database or cloud operations skills; they are not Google Professional Data Engineer exam preparation. Microsoft plans updates to the English-language DP-700 and DP-600 exams on October 19, 2026. Confirm the version covered by each MeasureUp product before purchase. Review DP-700 certification requirements.

Quick answer

What does a Data Engineer do?

A data engineer builds and maintains the pipelines, storage systems and processing workflows that turn raw data into reliable data products. The role involves ingesting data, writing SQL and Python transformations, orchestrating batch or real-time workloads, and ensuring datasets remain secure, timely and usable for analytics and AI.

Data engineers often use SQL, Python, Apache Spark and managed cloud services. Some specialize in Microsoft Fabric, Databricks or database infrastructure. Unlike data analysts, their primary responsibility is delivering and maintaining the data systems on which analysis depends. Projects and hands-on practice matter alongside certification preparation.

Data Engineer FAQs

Common questions about data engineering careers

Practical answers about the role, essential technologies, cloud certifications and realistic exam preparation.

What does a Data Engineer do?
A data engineer creates and operates pipelines and data platforms that collect, transform and deliver reliable data. Their work includes orchestration, storage, quality checks, access controls and ongoing performance monitoring.
How do I become a Data Engineer?
Learn SQL and Python, understand relational and analytical data, build an end-to-end pipeline with testing and logging, and gain hands-on experience on a cloud or Spark platform. Choose certifications aligned with your stack and seniority. There is no single mandatory sequence.
Which skills are most important for Data Engineers?
SQL, Python, ETL/ELT design, data modeling, data warehouses or lakehouses, orchestration, testing, version control, security and cloud services are core skills. Distributed processing with Apache Spark and streaming are valuable for many roles.
What is the difference between a Data Engineer and a Data Analyst?
Data engineers develop and maintain the pipelines and infrastructure that make datasets usable. Data analysts examine and visualize the resulting data to identify patterns and answer business questions. Both contribute to trusted data and often collaborate.
Is DP-700 a good certification for Data Engineers?
DP-700 is a strong match for professionals using Microsoft Fabric to build and operate data engineering solutions. It tests ingestion and transformation, implementing and managing analytics solutions, and monitoring and optimization. Microsoft updates its exam objectives periodically.
Should I choose DP-700 or DP-600?
DP-700 focuses on engineering data ingestion, transformation and Fabric platform workflows. DP-600 focuses more on analytics assets, semantic models and preparing data for analysis. Choose according to your actual responsibilities; both exams are scheduled for an English-language update on October 19, 2026.
Is Databricks Apache Spark certification the same as Databricks Data Engineer certification?
No. The Databricks Certified Associate Developer for Apache Spark validates Spark architecture and DataFrame programming. Databricks also offers separate Data Engineer credentials. MeasureUp’s linked DCAD Practice Test should not be presented as a Data Engineer Associate Practice Test.
Do I need cloud certification to work as a Data Engineer?
Not necessarily. Employers evaluate practical data pipelines, SQL or programming ability, reliability and problem solving. Certifications can help validate a chosen platform, but do not replace experience building and maintaining data solutions.
Can companies track Data Engineer training progress with MeasureUp?
MeasureUp offers business purchasing and reporting options for IT training teams. Administrators can use available score and objective-level reports to understand learners’ progress, depending on their selected plan and permissions.
