Why this role is notable

Wix is building an agentic 'Org Brain', a company-wide context layer and data catalog meant to be read by AI agents as much as by engineers, signaling that it is treating trustworthy shared data as infrastructure for its AI products.

Archetype: Engineering

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.

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

Data Services is a squad within Data Intelligence, made up of data oriented xEngineers. We're behind the context store, data catalog, and data quality infrastructure that serve most of Wix's roles, mainly xEngineers and creators, along with their AI agents. We own the full stack: Frontend, backend and data, while continuously deepening our AI fluency as a team. We value ownership, accountability, curiosity, and a willingness to dive into problems outside your comfort zone.
