What does a ETL Developer do?

A etl developer works across Informatica PowerCenter, SSIS, SQL to build and maintain systems in data & analytics. Day-to-day, you'll be writing code, reviewing pull requests, debugging production issues, and collaborating with product and design teams. It's the kind of role where you need to balance getting things done with doing them well.

The people who do well in this role tend to be strong in Python, AWS Glue, Snowflake, but more importantly, they know how to figure out what they don't know. Data & Analytics moves fast, and the best etl developers are the ones who can adapt without needing someone to hand them a playbook every time something changes.

Right now, etl developer roles pay in the range of $85,000 - $130,000, and most positions are looking for mid-level candidates. It's a competitive field, but companies are hiring. If you've got the right skills and can show real project work, you're in a strong position.

How to get there

Build your foundation in ETL developer

Before anything else, get solid on the fundamentals. For etl developer roles, that means understanding Informatica PowerCenter and SSIS at a level where you can explain them to someone else. Don't try to learn everything at once. Pick the core topics that show up in every job posting for this role and get genuinely good at them.

Get hands-on with Informatica PowerCenter and SSIS and SQL

Reading docs and watching tutorials won't get you hired. You need to actually build things with Informatica PowerCenter and SSIS and SQL. Set aside time every week to write code, run experiments, or practice in a real environment. Hiring managers can tell the difference between someone who has used a tool and someone who has just read about it.

Work on real projects

Find a messy dataset and clean it, analyze it, and present your findings. Kaggle competitions work, but a self-directed project stands out more. The goal is to have something concrete you can talk about in interviews. "I built X, it does Y, and here's what I learned" is worth more than any course certificate.

Get certified in Informatica Certified Professional

For etl developer roles, certifications like Informatica Certified Professional actually carry weight with hiring managers. They won't get you the job on their own, but they signal that you've put in structured effort. If you're choosing between certifications, pick the one you see mentioned most in job postings for roles you want.

Target your first etl developer role

Most etl developer positions are mid-level and pay around $85,000 - $130,000. When you're applying, tailor your resume for each job. Use the exact skills and keywords from the posting. Don't be picky about company size or brand name early on. A role where you'll learn fast is more valuable than a prestigious name on your resume.

Grow from here

Once you've got a couple years as a etl developer, you'll have options. Roles like Quantitative Analyst, Data Architect, Decision Scientist are natural next steps in data & analytics. The key is to keep building depth in your specialty while picking up broader skills like leadership, architecture, and cross-team collaboration. Your career path isn't a straight line, but this gives you a strong starting point.

Skills you'll need

These are the skills that show up most often in etl developer job postings. You don't need all of them on day one, but you should be working toward them.
