Job Description

Wix makes it possible for anyone to succeed online. Since 2006, we’ve grown to around 5,300 employees in 22 countries, launched over 40 products, and serve over 299 million users and their visitors worldwide. At Wix, we push you to innovate and evolve in non-traditional ways. We operate in collaborative, high-performing teams, building cutting-edge products and leveraging AI to redefine how our users create, manage and grow their dreams online.

 

Although we’re already industry leaders in web creation and business, our work is nowhere near done. Our goal is to become the main engine of the Internet so we can create a more open web for all.

We're proud to be an equal opportunity employer. Wix was built around the idea that everyone has the right to be successful, online. This same vision defines us as an employer: creating a work environment where everyone is welcome, and anyone has the right to succeed.

At Wix, velocity and reliability are the core principles behind shipping products. Join our Backend Engineering Guild as a Senior Backend Engineer for the CTO Team in Vilnius, where you’ll be at the heart of Wix’s technical operations.

In this role, you’ll collaborate with cross-functional teams, adapt to diverse workflows, and drive success by delivering innovative solutions that support the company’s strategic goals. You will have the opportunity to work hands-on with Scala, Java, and Node.js, delivering high-quality support and results.

 

In your day-to-day, you will:

• Work closely with diverse teams, adapting to their processes and respecting established workflows.

• Deliver innovative solutions while supporting teams in achieving their goals.

• Take a hands-on approach with Scala, Java, and Node.js to develop robust backend services.

• Plan, design, build, and maintain systems while working closely with Wix developers to improve their experience and eliminate velocity blockers.

• 3+ years of experience as a backend developer.

• Technical Stack: Hands-on experience with Java and Node.js.

• An in-depth understanding of Object-Oriented Programming (OOP) and SOLID principles.

• Skilled in debugging and investigating production issues, with the ability to recognize and address "bad code".

• A team player who values ownership and accountability, while always being ready to lend a hand and support each other.

• A versatile skill set with the ability to transition smoothly between platforms and diverse technical environments.

• A commitment to delivering consistent, timely results and a proven track record of meeting high-quality standards.

• Enthusiastic about solving critical business problems and conceiving unconventional, "out-of-the-box" solutions.

 

It’s an advantage if you:

• Are proficient in SQL and NoSQL databases.

• Have knowledge of gRPC and Protobuf.

• Are familiar with Scala or other functional and modern programming languages.

Our team is made up of six experienced developers from diverse backgrounds, creating a collaborative environment where meaningful technical discussions lead to elegant, effective solutions. We operate in small teams that work closely together at a high level. We value ownership and accountability, while always being ready to support each other when it matters.

 

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 5000 - 8000 Eur GROSS / month (Total compensation, including RSUs package)
