Job Description

Wix makes it possible for anyone to succeed online. Since 2006, we’ve grown to 5,000 employees in 17 countries, launched over 40 products, and serve over 230 million users and their visitors worldwide. At Wix, we push you to innovate, evolve in non-traditional ways, and grow outside your comfort zone. We operate in small teams that work closely together to create incredible things.

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 believe solving complex problems starts by building strong infrastructure and platforms supported by engineers working with cutting-edge technology.

As a dev-centric company, we rely on testing, implementing smart feedback loops, measuring impact, and using “fail fast” methodologies to keep our high-scale traffic and advanced products in constant progress with a 99.99% uptime.

• As a Backend xEngineer, you’ll design and own the core systems that impact millions of users, working with an AI-native focus to craft high-performance backend architectures and scalable, reliable platforms. In your day-to-day, you will:
• Design and own end-to-end backend systems and features that impact millions of users
• Focus on backend architecture and system design, making thoughtful trade-offs around scalability, reliability, security, and maintainability
• Take full ownership from data models and APIs to production systems and distributed architectures
• Use AI as an integral part of your daily work—for planning, design, execution and production, while ensuring AI-assisted outputs meet the highest production standards
• Work with modern technologies (e.g., Java, Scala, Node.js, Cloud, and CI/CD) while continuously evolving your toolkit with AI-powered tools
• Collaborate closely with product managers, designers, and engineers to shape solutions while ensuring production quality, observability, and long-term system health

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.

Qualifications

• 4+ years of experience in backend engineering and strong ownership of real production systems
• Strong software and system design skills: designing APIs, complex data flows, and scalable, maintainable architectures
• Experience using AI tools as part of your engineering workflow, with the ability to critically evaluate, validate, and iterate on AI-generated outputs.
• A mastery of software engineering best practices, including testing, code reviews, and identifying anti-patterns
• Curiosity for how systems work end-to-end: from product behavior to distributed systems, deployment pipelines, and data stores
• A mindset that values product impact, technical excellence, and proactive problem-solving in a fast-evolving AI-driven environment
• Skilled in reasoning and effectively communicating opinions while respecting others' approaches
