[Hiring] Senior Search Engineer @DataXstream

Role Description

Search is how our users get their work done. In OMS+, finding the right material, customer, order, or document in seconds can be the difference between a smooth order and a lost one, often across catalogs with millions of items and decades of enterprise history behind them.

We are looking for a Senior Search Engineer with OpenSearch expertise to join the team. The role is split between product and delivery:

• Help design and build the search capabilities that ship with the platform.
• Work with customer data and customer teams to make them perform in their environments.

The focus throughout is search design and build:

• Index and schema design
• Indexing pipelines fed from SAP source systems
• Relevance engineering
• The search APIs our TypeScript product stack consumes

What we need from this role is design judgement:

• How indexes should be shaped
• How queries should be written
• How to prove a relevance change improved results

Qualifications

• Deep, hands-on OpenSearch or Elasticsearch expertise, ideally with production search you designed and built yourself.
• Command of the query DSL, mappings, analyzers, and aggregations, and a working mental model of the relevance levers each one gives you.
• Proven relevance engineering: you have measurably improved search quality and can explain how you proved it.
• A solid grasp of how index and cluster design choices drive performance: sharding, mapping design, query cost, Lucene fundamentals, etc.
• Strong debugging ability for search problems: slow or expensive queries, mapping and analyzer mistakes, and results that are wrong in ways users notice before dashboards do.
• Experience building high-throughput ingestion and indexing pipelines against systems of record.
• Proficiency in TypeScript/JavaScript and/or Python for building services, pipelines, and tooling.
• Comfort working directly with customers and delivery teams.
• Comfort working alongside a separate platform or IT team: specifying requirements, handing off cleanly, and collaborating on diagnosis rather than reaching for root access.
• Clear communication and a habit of documenting decisions, particularly around relevance trade-offs.
• Bachelor's degree in Computer Science or a related technical field, or equivalent practical experience.

Requirements

• Vector and semantic search experience: embeddings, the OpenSearch k-NN plugin, hybrid ranking, or learning-to-rank.
• Familiarity with OpenSearch Dashboards, Data Prepper, Logstash, or Kafka-based ingestion.
• Experience with SAP or ERP material master and catalog data, including part numbers, cross-references, and unit-of-measure complexity.
• Query understanding: entity extraction, intent classification, spell correction, autocomplete.
• Multi-tenant search architecture and tenant data isolation.
• Experience in a customer-facing implementation, delivery, or professional services capacity.
• Working knowledge of containers and Kubernetes.
• Contributions to OpenSearch, Lucene, or other open source search projects.
