xEngineer – Backend Expertise - Wix Payments

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

Requirements: 

• 4+ years of experience as a software engineer with strong ownership of production systems
• Expertise in at least one core domain (e.g., frontend, backend, mobile) with the ability and motivation to operate across stack boundaries
• Strong software and system design skills, including designing APIs, data flows, and scalable, maintainable architectures
• Experience integrating AI tools into the engineering workflow, with the ability to evaluate, validate, and iterate on AI-generated outputs
• End-to-end curiosity for systems, from product behavior and UX to distributed systems, deployment pipelines, and data stores
• A mindset that values product impact, technical excellence, collaboration, and continuous growth in a fast-evolving, AI-driven environment

About the Team 

We are Engineering at Wix – a team of AI-native xEngineers with deep expertise in frontend, backend, or mobile, who use AI support to take ownership over projects end-to-end. We work in a fast-paced, dynamic development environment with autonomous teams that never compromise high quality standards. As AI increasingly generates production code, we dedicate more and more of our time developing the skills we believe are critical for today and tomorrow: system design, architecture, scalability, reliability, and security.
