xEngineer – Backend Expertise

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. 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 We are Wix's Backend xEngineering group – a team of xEngineers who specialize in backend development. We provide integrated tools for microservice development to improve developer productivity and best practices. As xEngineer, we use AI-native workflows that allow us to concentrate on what truly requires human judgment: system architecture, security, and scalability. To handle high-scale traffic, our team runs production across distributed data centers worldwide. We take complete ownership of our systems, and maintain the deep expertise required to manage a global engine of the internet.
