Responsibilities:

• Lead the design, build, tuning and operation of the search layer of the client's website. The role delivers secure, grounded, and supportable conversational search using Lucidworks Fusion.

• Translate customer and business needs into scalable index and query pipelines across web, content, commerce, and AI platforms.

• Search Platform and Retrieval Engineering

• Design and implement collections, schemas, connectors, index/query pipelines, query profiles, and REST API integrations in Lucidworks Fusion or an equivalent platform.

• Build and tune lexical, semantic, vector, and neural hybrid retrieval, including embeddings, blend weights, thresholds, boosting, filters, facets, synonyms, and fallback behavior.

• Use signals and behavioral data to improve relevance, recommendations, personalization, and popular or successful results.

• Create relevance benchmarks, automated regression tests, citation and grounding tests, latency targets, and per-query cost measures.

• Troubleshoot ingestion, indexing, Solr, Kubernetes/AWS, APIs, pipelines, model endpoints, and front-end integrations.

• Conversational Search and Generative Ai

• Engineer single-turn and multi-turn search flows with intent recognition, entity extraction, query rewriting, clarification, and session context.

• Implement grounded RAG that retrieves approved sources, cites evidence, and suppresses or falls back when evidence or confidence is insufficient.

• Integrate with enterprise LLM services and Client AI Gateway using prompt controls, model configuration, rate limits, error handling, latency budgets, and cost governance.

• Tune experiences for product numbers, specifications, availability, certificates, manuals, application notes, and related support content.

• Apply guardrails for transactional or product-SKU queries, low-confidence grounding, and zero-result scenarios.

• Integration, Delivery, and Operations

• Partner with AEM and front-end engineers to deliver accessible search results, conversational answers, follow-up suggestions, and facets aligned with the Client Design System.

• Manage Fusion configuration as code through GitLab, peer review, automated testing, and CI/CD practices.

• Instrument click-through, zero-result, no-click, reformulation, abandonment, task completion, latency, and pipeline-health metrics.

• Produce architecture diagrams, deployment documentation, runbooks, configuration standards, and knowledge-transfer materials.

• Work with security, privacy, legal, architecture, product, content, and business teams on access controls, data handling, AI guardrails, and release readiness.

• Participate in Client AI-DLC and Agile delivery cadence.

Requirements:

• Bachelor's degree in Computer Science, Information Systems, Engineering, Data Science, or a related discipline, or equivalent practical experience.
• 5+ years in search engineering, information retrieval, or enterprise application development, with substantial experience in Lucidworks Fusion or comparable platforms such as Solr/Lucene, Elasticsearch/OpenSearch, Algolia, Vespa, or Azure AI Search.
• Hands-on knowledge of schemas, analyzers, tokenization, synonyms, faceting, boosting, filtering, relevance scoring, query debugging, connectors, signals, custom pipeline stages, and REST APIs.
• Practical experience with semantic search, embeddings, approximate nearest-neighbor retrieval, neural hybrid ranking, relevance evaluation, RAG, grounding, prompt design, citations, guardrails, and fallback patterns.
• Experience with multi-turn context, session design, intent classification, and entity extraction.
• Experience deploying or operating search workloads in AWS and Kubernetes, including observability and production troubleshooting.
• Proficiency in Java and/or Python, JSON, HTTP APIs, Git, automated testing, and CI/CD.
• Ability to convert customer journeys and business requirements into technical designs, backlog items, acceptance criteria, and measurable outcomes.
• Clear communication with technical and nontechnical stakeholders; able to work independently, prioritize competing work, resolve ambiguity, and transfer knowledge
