Job Description

We are looking for a Server Engineer to develop and operate Wix's AI-powered search infrastructure - a high-performance, distributed platform that combines information retrieval with vector search, machine-learned ranking, LLMs, and intelligent orchestration. This role blends deep systems engineering with cloud-native infrastructure: you will own foundational components that serve search at the scale of hundreds of millions of sites and users, and drive key decisions on their architecture, design, and implementation.

You'll work across the full lifecycle of the systems you build - from design and development to how the service is deployed, operated, monitored, and scaled in production.

Design, build, and operate core search components — indexing pipelines, retrieval algorithms, ranking systems, and vector/hybrid search — that run reliably at large scale
Develop streaming and batch data-processing systems for search index construction in a high-load environment
Integrate machine-learned models and LLMs into the serving path, applying AI to make sense of data in real time
Design, deploy, and operate cloud-native systems on AWS and Kubernetes infrastructure
Push the limits of hardware and Linux performance through low-level optimization, profiling, and systems-level tuning

Requirements

Strong background in systems design and backend development (Java, Scala, Python)
Proven experience in building high-load, distributed, and performance-sensitive services, with ownership of the full project lifecycle — build, deploy, operate, and scale in production
Solid Experience with cloud infrastructure and tools (AWS, Kubernetes, Docker, Helm)
Strong knowledge of algorithms and data structures
Understanding of Linux internals and of performance tuning

Preferred

Experience in search systems and databases, understanding of search fundamentals: indexing, query parsing, ranking, and relevance
Familiarity with vector search / ANN, embeddings, and machine-learned model inference or LLM-based systems
Experience with monitoring and logging tools (Grafana, Prometheus, ELK)

About the Team

We are Wix's AI-Powered Search Team responsible for design, development and maintenance of Wix's Search infrastructure. A modern AI-powered search infrastructure at Wix is no longer just a "search engine." It's a platform that combines traditional information retrieval with machine learning, large language models (LLMs), knowledge representation, and intelligent orchestration. This cutting-edge search infrastructure is one of the company's core AI platforms. And we work on high-performance distributed systems, modern AI technologies, and cloud-native architecture, with significant influence on technical directions that impact multiple products.
