ETL DeveloperJob Description, Salary, Career Path, and Trends
Are you looking for a role that lets you apply your expertise in a wide variety of skill sets? Do you possess a range of concrete skills, like software engineering, database development, and more? Well, a career as an ETL developer might be right for you!
ETL developers do the heavy lifting when it comes to ETL: Extracting, transforming, and loading data. They design and maintain data storage systems and ensure that they provide business-relevant data.
In other words, businesses create massive amounts of data that need to be both stored and quickly retrieved or changed. The job of the developer is to make sure the business has the right tools for the job. They then create the right storage options and provide optimized delivery systems to and from these storages.
Developers work closely with programming languages, databases, and data modeling systems. Beyond that, they’ll be working on a wide variety of tasks ranging from team management, technical hurdles, and meeting and coordinating with others outside the department regularly.

Typical work environment
ETL developers will generally work in an office as a part of a team. Typically, this job can only be done in-office due to the number of interactions between teammates, department heads, other developers, and stakeholders necessary. That being said, it may be possible for this job to be done remotely.
This job may require light or significant travel, depending on employer needs. The number of meetings and presentations required, and the size of the company will dictate these needs.
The standard workweek for an ETL developer will be between 40-60 hours per week. Some weeks will be heavier to meet deadlines or complete special projects, while others are slower during down periods. Companies extending offers of overtime and on-call needs make this average shift higher in hours worked, and an employer with predictable intervals of work, or excellent forecasting may move closer to 40 hours or less.
As ETL developers work in a variety of industries, there are many institutions that offer certifications, including:
Oracle Certified Associate. OCA Certification combines the training, testing, and experience to develop a strong foundation for Oracle9i techniques. Completion of exam required for accreditation.
IBM Certified Solution Developer. This certification demonstrates efficient and scalable DataStorage development. After the completion of the exam, you’ll prove you’re capable of configuring scalable parallel environments in multiple configurations.
Teradata 14 Certified Master. This certification demonstrates you’ve mastered the knowledge and skills necessary to define, retrieve, manipulate, and transform data within SQL using ANSI standard and Teradata extensions.
The first step companies look for in the hiring process is the completion of a degree. Gaining at least a Bachelor’s degree, (preferably in a computer science or related field), will go a long way in demonstrating your proficiency as a candidate.
After completing a degree, obtaining advanced computer knowledge, database architecture experience, and data profiling, virtualizing, and warehousing is a great next step.
Either by way of certification or on-the-job training, as you deepen your understanding of these skills and gather more, you’ll become a more desirable candidate.
Further, accruing time management, project management, organizational, and communication skills on top of technical training and applicable hard skills, you’ll be the most competitive candidate in the field.
