Senior Java Engineer with Solr/OpenSearch (#5020)

N-iX, Київ, Львів

Що робити

Design, develop, and maintain high-performance backend Java services (primarily Spring Boot) that integrate with search engines.
Build complex search features for the frontend, including faceted navigation (filtering), multi-tenant searching, real-time autocomplete/typeahead, and spell-checking suggestions.
Utilize Java client libraries (such as SolrJ or AWS SDKs) to construct efficient, programmatic queries.
Take ownership of the search schema design, deciding how complex data structures should be analyzed, tokenized, and stored for optimal retrieval.
Build robust ETL pipelines in Java (potentially using Kafka or other messaging systems) to synchronize data from primary SQL databases into the search indices in near real-time.

5+ years of professional experience in backend software development using modern Java (Java 8+, Spring Boot ecosystem).
Strong, demonstrable experience with Search Technologies. This means either:
Hands-on production experience configuring, managing, and developing against Apache Solr (understanding schema.xml, solrconfig.xml, Zookeeper integration).
OR deep foundational knowledge of Lucene-based search concepts (inverted indices, analysis chains, TF-IDF/BM25 scoring logic) with the ability to quickly apply that to Solr.
Hands-on experience with AWS OpenSearch (or Elasticsearch) in a managed cloud environment.
