Join a highly-skilled development team based in Vilnius, where you'll create features used by millions of users around the world. In your day-to-day, you will:

• 5+ years of software engineering experience
• Proficiency in at least one of: Scala, Java, or Node.js

• Good communication and organizational skills
• Pragmatic approach to quality — you know when to move fast and when to be rigorous
Wix Functions is a team that moves fast and takes pride in what we ship. Our work touches millions of websites and users  — so the scale is real, and so is the responsibility. We value engineers who take ownership, take pride in collaboration,  aren’t afraid to innovate and question how things are done. Team spirit is in everything that we do.
Wix is evolving toward a more full-stack, AI-assisted way of working, so knowledge and tool sharing is a constant that helps us move forward together as a team. We’re looking for somebody who wants to work on hard problems, influence technical decisions and be open to learning new things. If you’re that kind of person,  this is a good place to be.
 
We offer: 
• Discount stock purchasing plans (ESPP)
• Health and personal accident insurance
• Daily lunch and snacks at the office
• Commuting allowance
• Discounted phone operator services and compensation for a new phone
• Free exercise classes and wellness activities
• Online courses and professional development
• Fun activities and team events
 
Salary range is 6000 - 8000 Eur GROSS / month (Total compensation, including RSUs package)
