Key responsibilities

• Develop feature logic for assigned capabilities within assigned feature suites

• Deliver full orchestration integration with the platform's cookbook-based orchestration component
• Integrate the RAG-layer retrieval pipeline to inform agent selection, routing and response generation

• Maintain question-and-answer baseline categorization

Required skills & experience

• 6+ years AI engineering experience with strong Python fundamentals

• Experience building or validating golden Q&A datasets for grounding LLM systems

Preferred qualifications

• Experience on a regulated or enterprise AI product
• Familiarity with LangGraph or comparable agent frameworks
• Direct experience replacing a template-based SPARQL approach with GraphRAG
• Experience coordinating with a separate KG validation team
• Experience with cookbook-style orchestration frameworks
• Experience writing forward-looking technical design documents (vs. shipping code) when scope calls for it
• Experience working within a per-sprint expansion cap rather than open-ended dataset growth
• Pharma/manufacturing terminology disambiguation experience
