- Must understand state management, agent loops, and reliable tool-calling.
- Experience with evaluations is a significant bonus.
- Knowledge Graphs & Ontologies : Experience building or working with ontologies.
- Advanced Memory Management : Implementation of "long-term memory" using vector databases and schemas to maintain context over long horizons.
- RAG & LLMs : Experience with RAG optimization (reranking, query transformation) and/or fine-tuning LLMs for domain-specific reasoning.
- Experience with GCP is preferred.
- Understands Secure SDLC practices.
Core Competencies :
