We are looking for an experienced xEngineer with a backend orientation to join the User Voice team.
User Voice is a platform that lets Wix hear its users at scale. It ingests feedback from millions of user interactions and transforms it into actionable insights through a multi-stage AI pipeline, combining natural language understanding, semantic representation and retrieval, and large-scale unsupervised clustering. The platform is expanding rapidly, onboarding new feedback channels and new types of user signals, and you'll be a driving force in shaping the backend architecture behind that growth, powering the insights that shape product roadmaps across Wix.
Responsibilities
- Design and evolve the platform's backend together with the team - a large-scale, event-driven microservices system processing feedback in real time and in batch
- Lead the expansion to new feedback channels and new types of insight, shaping how each one is brought into the platform reliably and at quality
- Build and improve the AI pipeline stages that turn raw feedback into structured, trustworthy insights - from LLM-based information extraction to semantic clustering
- Help establish evaluation as part of how the team ships - automated quality measurement, regression evaluation on model and prompt changes, and readiness criteria for new feedback channels
- Collaborate with data engineering, data science, and product to take capabilities from idea to production
- Treat reliability, scalability, and cost as core features of the platform
Requirements
- 5+ years of software engineering experience with a strong backend orientation - designing and owning distributed, event-driven systems at scale
- Hands-on experience building LLM-based systems in production - extraction pipelines, structured outputs, prompt and model lifecycle - and dealing with their real-world failure modes: quality, cost, and latency
- Strong prompt engineering skills - designing, iterating, and versioning prompts for reliable, structured results at scale
- Experience evaluating AI systems - defining quality metrics, building evaluation datasets, benchmarking and selecting models per task, and validating changes before they ship
- Working understanding of applied ML in production - embeddings, vector search, and clustering algorithms
- Solid grasp of large-scale data processing: pipelines, backfills, reprocessing, and warehouse-scale SQL
Nice to have
- JVM-language experience (Scala, Java, or Kotlin) and solid Python
- Experience with vector search engines or RAG architectures
- Background in voice-of-customer, feedback analytics, or similar insight products
We offer
- Full-time employment
- Work in Tel Aviv
