Data Engineer vs Data Analyst: What Are the Differences in 2026?

Two Complementary Roles in the Data Ecosystem

Data Engineer and Data Analyst positions are often confused, yet their roles are very different.

If we had to summarize their main missions:

• The Data Engineer is the architect who makes data available
• The Data Analyst exploits the data prepared by the Data Engineer

At Datakhi, we recruit both profiles. Here's our guide to better understand these roles and choose your path.
