Job Description

Every AI-powered data analysis or coding at Wix depends on one thing: trustworthy, always-current data. You'll help build the agentic “Org Brain” that makes that possible - a company-wide context layer and data catalog that both engineers and AI agents rely on to understand what's true across Wix. You'll join Data Services, a domain squad within Wix's Big Data and Analytics Platform group, based in Vilnius, focused on solving these problems and more at scale.

• Take end-to-end ownership of the platforms that power our context store and data catalogs, from data ingestion to agentic search and serving.
• Work hands-on across the full stack, partnering with cross-functional teams to keep pace with fast-evolving AI needs.

Qualifications

• Exceptional and highly motivated Full Stack Engineer with at least 5 years of experience
• Strong proficiency in at least one backend language (Go, Java/Scala, Node.js or similar)
• Expertise in designing, building, and owning end-to-end production-grade services as well as web applications using modern web frameworks (React, Angular, Vue, Next, etc.)
• Hands-on experience integrating AI/LLM capabilities into production systems, including agentic workflows, tool-calling, or MCP-based integrations
• Experience collaborating with product managers, UX specialists, and stakeholders
• Strong communication skills in English
