What Does an ETL Developer Do?
First off, what is an ETL developer and what do they do?
ETL stands for Extract, Transform, Load. This position falls somewhere between data analysis and data engineering. It requires the developer to have a working knowledge of both, as well as creative problem-solving skills.
An ETL developer is a software engineer who creates a process to extract, convert, and load data into a warehouse that they build and maintain.
A few responsibilities of an ETL developer include:
- Understand the data needs and unique challenges of the client to create a developmental strategy for a solution.
- Ensure data accuracy.
- Create a solution to make data more organized and accessible, allowing for easier data consumption and understanding from non-technical people.
- Lead data model design and implementation and the construction and implementation of operational data storage.
- Develop a process for how to easily move, transform, and store data moving forward using data engineering and analytics tools.
- Communicate with other team members to understand their challenges and to ensure the creation of solutions that work for them.
When to Hire an ETL Developer
Your business should hire an ETL developer when you need sophisticated data solutions that you’re unable to create and maintain on your own.
A few examples of when it may be time to hire an ETL developer include:
- Building and maintaining a data warehouse
- Migrating data from one system to another
- Integrating new data sources into existing ones
- Data system upgrades or replacements
- Optimizing data processing performance
- Ensuring data meets regulatory requirements
- Data cleaning or organization
- Need for real-time data processing
What to Look for in an ETL Developer
Alright, so you’ve determined you need an ETL developer.
What do you need to look for in one?
Your ETL developer should have the following skills and qualifications:
ETL Developer Skills
Make sure your ETL developer has these skills:
- Knowledge of ETL Tools and Software (including Talend, Informatica, and Pentaho)– These tools provide a graphical interface for the developer, usually drag and drop. The developer can see the entire workflow from source to target, streamlining the development process and making things run more smoothly.
- SQL Competence (query performance tuning, index management, etc.)-Since SQL is the primary language necessary for every step of ETL, an ETL developer must have a solid grasp of this popular database language.
- Proficiency in Scripting Languages (Python, Perl, Bash, etc) can come in handy when other database languages fail
- Understanding of Data Modeling Concepts and Parameterization
- Problem-solving Skills- Including knowledge of debugging and how to troubleshoot that will undoubtedly arise during the process.
Qualifications for an ETL Developer
Formal qualifications and education requirements for an ETL developer include:
- Years of Experience– Companies may require an advanced ETL developer with multiple years of experience in the ETL development or similar software engineering field.
- Data Analytics Background– A good way for software engineers to get into ETL is to first gain experience in data analytics.
- Bachelor’s Degree– Though not always required, many businesses prefer candidates who have a Bachelor’s degree in computer science or IT-related field of study.
- Additional Certifications– Earning a certificate in things like business data, ETL language, and other coding languages shows a commitment to understanding ETL processes.
ETL Developer Characteristics
Aside from the hard skills, there are a few soft skills and personality traits that make for a great ETL developer.
A few of them include:
- Communication Skills– An ETL developer must discuss goals and data with team members which often include people with little to no tech experience. Clear communication skills are a must.
- Creativity– Creating the best data solutions often requires some out-of-the-box thinking.
- Analytical Mindset– Since an ETL developer’s primary duties are to extract, interpret, and store data, an analytical mindset is necessary.
- Detail-Oriented– Data storage and transformation can get very specific, so an ETL developer needs to be able to make sure they don’t miss anything.
- Project Management Skills– The ETL developer will often be leading teams and working on multiple things at once, so they must be able to lead and manage multiple moving parts.
