Agentic AI / Semantic Solutions Architect

Position : Agentic AI / Semantic Solutions Architect #19572
Location :  Atlanta, GA, USA (Hybrid on site)
Duration: 12+ Months
Experience : 13+ Years

Role Overview
We are seeking a highly skilled Agentic AI / Semantic Solutions Architect to design and prototype advanced agent-layer architectures that operate on enterprise semantic data platforms. This role sits at the intersection of LLM orchestration, knowledge graphs, and semantic data modeling, focusing on building POC-level intelligent agent solutions rather than production-scale systems.

The ideal candidate will have deep expertise in agent-based AI systems, GraphRAG architectures, and context engineering, with the ability to design frameworks where autonomous agents can effectively interpret and reason over structured knowledge.

Key Responsibilities
Architect and design agentic AI workflows that consume outputs from semantic layers, including knowledge graphs, ontologies, and metadata catalogs
Develop and prototype GraphRAG pipelines that combine graph traversal with vector-based retrieval for accurate, domain-grounded responses
Define and implement context engineering strategies, including metadata injection, chunking, and semantic optimization for LLM prompts
Design and build Model Context Protocol (MCP) server patterns to enable seamless interaction between agents and semantic data systems
Develop LLM orchestration workflows using frameworks such as LangChain, LangGraph, LlamaIndex, or AutoGen
Build pipelines for automated metadata extraction and semantic tagging using NLP and LLM-based approaches
Collaborate with Semantic Data Architects to ensure ontologies and graph structures are optimized for agent traversal and querying
Prototype agent-based solutions for business use cases such as:
Credit risk analysis
Customer data onboarding workflows
 

Mandatory Skills
Strong expertise in Agentic AI architecture (multi-agent systems, tool usage, planning loops)
Hands-on experience with GraphRAG design (hybrid graph + vector retrieval systems)
Experience in LLM orchestration frameworks:
LangChain, LangGraph, LlamaIndex, or AutoGen
Deep understanding of context engineering techniques (chunking, windowing, semantic compression)
Experience designing and integrating Model Context Protocol (MCP)
Strong knowledge of semantic systems such as:
Knowledge graphs
Ontologies
Metadata-driven architectures
 
Nice to Have Skills
Experience with Google Vertex AI (Agent Builder / Search)
Knowledge of Google Cloud Platform Spanner Graph
Familiarity with metadata platforms like Collibra or Google Dataplex
Experience with vector databases:
Pinecone, Weaviate, pgvector, Vertex AI Vector Search
Prior experience in regulated domains such as financial services or legal systems
