Words from the Team

As a Frontend Developer, you’ll join an autonomous team of diverse individuals. You’ll work closely with Product Managers, UX Designers, Backend Developers and other driven people.
You’ll also be part of the cross-team “frontend guild”, in which we share articles, knowledge, breakfasts and silly memes.
All three teams strive to deliver software that is robust, secure, scalable, operable, maintainable, usable and reliable.
Come meet us!

Why you will love it here

Safe work culture - we value respect, kindness, and the right to fail.
Flexible hours - we schedule our days in order to be effective at work, while also being able to enjoy life’s important moments.
Great people - we value people skills as much as technical skills and strive to keep things friendly and laid back. Still, that does not prevent us to be passionate leaders in our domains. Our 300+ SonarSourcers from 33 different nationalities can relate!
Work-life balance - keeping a healthy work-life balance is important. This is why we have a hybrid work policy and some people prefer working some days from home.
Always keep learning - in an ever-changing industry, learning new skills is a must, and we're happy to help our team to acquire them.

What we do

Sonar was started by a team of developers that wanted to change the way code is built in an agile development process. The company was created to develop the open-source tool SonarQube, which is now the standard in code quality management with over 350,000 instances deployed today. Every day we are focused on solving developers’ next big problem.

Who we are

At Sonar we believe in people, excellence, and delivery. We’re a team of problem solvers and overachievers who seek out others who are also passionate and relentless in their respective missions. We want to work with people who are ready to fasten their seat belts and be part of an incredible ride. We work hard not because we’re told to, but because we genuinely love what we do and do what we love. If there’s one main message we want you to remember about us, it’s that we push others to be best in class at whatever they do: choose your battle, innovate, take risks, and lead change. Join us; we’ll be smarter and stronger together.
