Business responsibilities of a Data Engineer
The following information is from a book "Fundamentals of Data Engineering" by Joe Reis and Matt Housley.
Business Responsibilities of a Data Engineer
While technical prowess is essential, this book argues that a Data Engineer's career success often hinges on "soft" skills and business acumen rather than coding ability alone.
The Five Core Responsibilities:
Communication & Organizational Awareness
You must act as a bridge, communicating effectively with both technical teams and non-technical stakeholders.
Success requires understanding the organization's structure: who reports to whom, where political silos exist, and how to build rapport across them.
Requirement Scoping
It is not enough to just build; you must know what to build.
This involves gathering requirements, ensuring stakeholders agree with your assessment, and understanding the business impact of your technical decisions.
Cultural Adoption (Agile/DevOps/DataOps)
Treat these methodologies as cultural foundations requiring human buy-in, rather than just technical solutions or tools to be installed.
Cost Management (FinOps)
Focus on providing outsized value while keeping costs low.
Key metrics to master include Time to Value, Total Cost of Ownership (TCO), and Opportunity Cost.
Continuous Learning
Because the data field moves at "light speed," you must be able to filter noise (fads) from relevant developments.
Focus on sharpening fundamental knowledge while learning how to learn.
Key Takeaway
A successful Data Engineer zooms out to see the big picture. The differentiator between an average engineer and a great one is usually the ability to navigate the organization and align technology with business value, not just the ability to write code.
