Qualifications

• Hands-on experience with LLMs such as GPT, Claude, Gemini, Llama, or similar models.
• Strong prompt engineering skills, including prompt templates, system prompts, few-shot prompting, and response tuning.
• Develop AI-powered applications using LLM APIs, RAG workflows, enterprise data sources, and backend services.
• Knowledge of RAG, embeddings, vector databases, semantic search, and knowledge retrieval workflows.
• Ability to evaluate and improve AI responses for accuracy, relevance, completeness, tone, and instruction following.
• Understanding of NLP concepts, hallucination mitigation, prompt injection risks, guardrails, and responsible AI practices.
• Knowledge of healthcare data privacy and secure sensitive-data handling, including HIPAA-aligned PHI/PII practices, data minimization, de-identification, masking, access controls, auditability, and responsible use of healthcare data in AI workflows.
• Experience with MCP servers, cloud platforms, APIs, backend services, and production deployment is preferred.
• Experience integrating AI agents with healthcare, health records, or regulated industry systems.

Responsabilités

• Design, develop, and optimize prompts for Large Language Models (LLMs) to improve accuracy, reliability, and business outcomes.
• Build and configure Agentic AI solutions that leverage planning, reasoning, memory, and multi‑step task execution capabilities.
• Develop and integrate MCP (Model Context Protocol) tools, enabling AIagents to securely discover and interact with enterprise systems, APIs, and data sources.
• Design agent architectures, tool‑calling frameworks, retrieval mechanisms, and context management strategies.
• Collaborate with product managers, architects, and engineering teams to translate business requirements into AI‑driven solutions.
• Implement Retrieval‑Augmented Generation (RAG), knowledge grounding, and context orchestration patterns.
• Define evaluation frameworks and prompt testing methodologies to measure agent performance, quality, and reliability.
• Ensure AI solutions adhere to security, compliance, governance, and responsible AI standards.
• Support deployment, monitoring, troubleshooting, and continuous improvement of AI agents and MCP‑enabled workflows.
• Contribute to architecture reviews, technical design documentation, and engineering best practices for AI platforms.
