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

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
