AI Architect – Agentic Systems (LLM & Multi-Agent Solutions)

Job Description

We are looking for a highly skilled and hands-on AI Architect to design and lead the implementation of multi-agent (agentic) systems in enterprise environments. 

This is not a prompt engineering or chatbot role. We are focused on building production-grade AI systems, where multiple agents collaborate, reason, and execute complex workflows integrated with real business processes.

Key Responsibilities

• Design multi-agent architectures (task decomposition, orchestration, coordination patterns)  

• Define how LLM-powered agents interact with:  

• Enterprise data platforms 

• APIs and tools 

• Operational workflows 

• Lead agentic systems from PoC to production with model, cost, security, privacy, and responsible AI guardrails 

• Establish  observability, tracing, feedback loops, and controls for agent behavior 

• Define memory strategies (short-term, long-term, contextual grounding) 

• Collaborate with data, platform, and engineering teams to integrate AI into core systems 

• Guide and train teams on best practices for scalable and reliable AI systems 

Qualifications

What We’re Looking For 

Core Experience 

• Strong background in software architecture and distributed systems 

• Hands-on experience building complex LLM-based applications  

• Experience designing complex workflows or orchestration systems 

• Solid understanding of RAG architectures, retrieval optimization, and retrieval quality 

LLM & AI Foundations 

• Strong understanding of Large Language Model (LLM) fundamentals, not just usage 

• Solid grasp of Transformer architecture (attention mechanisms, embeddings, tokenization) 

• Understanding of how LLMs are trained and behave:  

• Pretraining vs fine-tuning vs instruction tuning 

• Context windows and limitations 

• Hallucinations and mitigation strategies 

• Familiarity with NLP concepts:  

• Semantic similarity 

• Text embeddings and vector representations 

• Information retrieval principles 

• Ability to reason about model behavior and limitations, not treat LLMs as black boxes 

Agentic / AI-Specific 

• Experience with multi-agent frameworks (LangChain, Semantic Kernel, Agent Framework, CrewAI, or custom) 

• Experience on platforms for managing the lifecycle of generative AI applications and agents like Amazon Bedrock (AWS), Google Vertex AI (GCP) or Azure AI Foundry 

• Familiarity with protocols like: MCP, UCP, A2A, AP2 

• Familiarity with:  

• Tool use / function calling 

• Agent coordination patterns 

• Memory and context management 

• Experience evaluating and improving LLM reliability and accuracy 

Engineering & Platform 

• Cloud experience (AWS, Azure, or GCP) 

• Strong coding skills (Python preferred) 

• Experience integrating AI with enterprise systems (APIs, data platforms, event-driven systems) 

What Makes This Role Different 

• Focus on systems, not isolated models 

• Real enterprise use cases, not experimental demos 

• Opportunity to define architecture patterns for agentic systems 

• Work at the intersection of AI, data, and distributed systems
