Required Skills:

Search & Indexing Fundamentals

· Hands-on experience with Lucene-based search platforms (Solr, OpenSearch, or Elasticsearch)

· Understanding of index schemas/mappings: field types, stored vs. indexed, doc values, multi-valued fields

· Familiarity with text analysis pipelines: tokenizers, filters, analyzers (index-time vs. query-time)

· Ability to inspect an index directly - querying fields, checking term vectors, using analysis APIs

Data & Transformation

· Ability to trace raw source data through an ingestion pipeline into indexed fields

· Comfort reading structured/semi-structured data formats (XML, JSON)

· Understanding of data normalization and transformation patterns

Query & Testing

· Skill in crafting targeted test queries to expose behavioral difference

· Experience with structured or Boolean query languages (experience with custom parsers a plus)

· Ability to design and execute parity/regression test cases at multiple levels: index content, query results, ranking, facets, highlighting

Development

· Java proficiency - able to read, debug, and make targeted changes to Java codebases

· Familiarity with Maven or Gradle build systems

AI-Assisted Analysis & Development:

· Proficiency using AI coding assistants (e.g. Claude Code) to investigate complex problems, generate hypotheses, and draft code changes

· Ability to formulate precise, context-rich prompts that produce actionable results from an AI assistant

· Comfort working in an AI-augmented development workflow: reading and critically evaluating AI-generated output before applying it

Analysis & Communication:

· Ability to identify root cause of parity differences and attribute them to a specific layer (ingestion, schema, analyzer, query parser)

· Able to produce clear, actionable defect reports for developers

Preferred skills:

· Experience with custom Lucene analyzers or codec plugins

· Python scripting (data inspection, test automation, reporting)

· Familiarity with OpenSearch REST API and index management

· Experience with SQLite or other lightweight databases for test result storage

· Search engine certifications (Elastic, OpenSearch)

· Experience with parallel/comparative testing frameworks

· Background in a domain with complex structured data (legal, scientific, patent, medical)
