Fullstack Engineer - OS

Company 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 282 million users and their visitors worldwide. At Wix, we push you to innovate, evolve in non-traditional ways, and collaborate. We operate in small teams that work closely together at a high level. 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.

As a Full Stack Developer for one of Wix's latest AI products, you’ll play a key role in shaping both the product and its technical vision from day one. You’ll build robust infrastructure that drives every aspect of the experience. You’ll design and develop scalable APIs, core runtime systems, and extensible UX frameworks. In your day-to-day, you will:

• Build infrastructure to enable the extendability of Wix’s existing business solutions  

• Design and develop APIs for internal and external users  

• Work on application runtime and UX infrastructure used by millions of users  

• Collaborate with internal teams, including R&D developers, UX designers, and business analysts, to align requirements and dependencies  

• Make architectural decisions that balance speed, maintainability, and performance  

At Wix, we believe our best work happens together. Our work model is fully in person, with 5 days a week from our office. Flexibility remains a core value at Wix and special requests are handled thoughtfully at the team level.

• 5+ years of experience with modern JavaScript frameworks (React, Angular, or Vue), languages (TypeScript, ES6+), and build tools (Vite, Next.js, SWC, or similar)  

• Strong understanding of backend fundamentals, including API design, data flow management, and scalable system architecture (experience with Node.js or Scala is a plus)  

• Strong curiosity about how things work under the hood, from async programming to caching, deployment pipelines, and database design

• A collaborative mindset with a passion for craftsmanship and continuous learning 

We are part of Wix's OS team, a vibrant and innovative group committed to developing unified platforms that empower millions. Our work spans crucial platforms like Wix’s back office, Studio workspace, and dev center. We’re instrumental in enabling rapid product development and deployment while ensuring scalability and consistency. As part of the OS team, you’ll be instrumental in delivering impactful products to a broad user base, from DIY enthusiasts to enterprise clients.
