• Implement and optimize multi-agent systems using frameworks such as LangGraph, CrewAI, AutoGen, Semantic Kernel, or OpenAI Agents SDK
• Create orchestration patterns including planner/executor, supervisor/worker, and tool-calling workflows
• Build RAG pipelines with embeddings, chunking strategies, hybrid search, retrieval evaluation, and enterprise data grounding
• Architect reusable AI design patterns including human-in-the-loop workflows and multi-agent coordination models
• Apply agent integration and communication standards (MCP, A2A, OpenAPI, REST, gRPC)
• Lead technical delivery of AI projects, managing timelines, dependencies, and stakeholder expectations
• Ensure delivery adheres to AI governance, data privacy, and regulatory frameworks
• Support pre-sales activities through technical solutioning, demos, and PoC development
• Apply observability and monitoring using tools like Langfuse, Arize, and OpenTelemetry
• Contribute to architecture decisions and technical standards across engagements

Requirements

• 6+ years in AI/ML engineering, data science, or applied AI roles within professional services or enterprise environments
• Proven experience building and deploying Generative AI and Agentic AI solutions into production
• Expertise in LLMs, advanced RAG strategies, prompt engineering, and model evaluation approaches
• Hands-on experience with multi-agent orchestration frameworks (LangGraph, CrewAI, AutoGen, Semantic Kernel)
• Familiarity with orchestration protocols such as MCP, A2A, and OpenAPI-based integration
• Strong Python development skills and knowledge of CI/CD, DevOps, and cloud-native architectures
• Practical experience with Azure (Azure OpenAI, Azure AI Foundry, AI Search) and familiarity with AWS or GCP
• Proficiency with containerized deployment, MLOps tooling (MLFlow, Airflow), and infrastructure-as-code practices
• Bachelor’s or Master’s degree in Computer Science, Data Science, or related field

Nice to Have

• Experience with Azure AI Agent Service or Microsoft Agent Framework
• Familiarity with vector databases (Pinecone, Weaviate, Qdrant, Milvus)
• Knowledge of AI safety techniques such as guardrails, bias mitigation, and model explainability
• Understanding of Intelligent Document Processing, data lineage, and distributed memory for agent systems
• Experience enabling responsible and auditable AI governance
