What is a Data Infrastructure Engineer?
A Data Infrastructure Engineer designs, implements, and maintains the systems that manage an organization’s data. Their work ensures that this data is always available, reliable, and of high quality, providing the backbone for data-driven decision-making within businesses.
To get a better understanding of their responsibilities, we analyzed 41 job postings on LinkedIn and found these key duties:
- Designing and Implementing Data Pipelines: The primary responsibility in 90% of the job postings is creating and managing data pipelines. This ensures that a company’s data flows seamlessly from various sources to storage systems and data warehouses, ready for analysis and business insights.
- Managing and Optimizing Databases: 85% of job postings emphasize the importance of database management. Engineers keep databases efficient and quick to retrieve data through regular maintenance, indexing, and optimizing queries for better performance. (Check out our Ultimate Guide To Data Quality for more on this topic.)
- Monitoring and Ensuring Data Quality and Performance: In 68% of job postings, engineers use data observability tools such as Monte Carlo to monitor the health and performance of data systems, ensuring data quality, detecting anomalies, and troubleshooting issues to keep data pipelines reliable. For a deep dive into these practices, see our guide on Data Observability For Dummies®.
Data Infrastructure Engineers also implement governance and quality frameworks to maintain data integrity and consistency. They set up redundancy and backup solutions to protect against data loss, ensuring data is always ready for business intelligence and analytics.
Difference Between a Data Infrastructure Engineer and a Data Science Engineer
With the names being so similar, you might naturally wonder how Data Infrastructure Engineers and Data Science Engineers differ.
Simply put, Data Infrastructure Engineers focus on building and maintaining data systems, while Data Science Engineers analyze this data to build predictive models. Both roles require strong programming skills and database knowledge, but their primary responsibilities differ.
