Job Summary Fiche de poste : We are seeking a highly skilled AI Engineer experience in Software Development, Data Science, or Machine Learning to design, develop, and deploy cutting-edge AI systems leveraging Large Language Models (LLMs), Chatbots, Retrieval-Augmented Generation (RAG), and agentic AI architectures. This role involves hands-on development with LLMs, embeddings, RAG pipelines, and multi-agent systems using modern frameworks like LangChain, LangGraph, and LlamaIndex. The ideal candidate has experience with Vertex AI on GCP and IBM WatsonX, fine-tuning, and Agent Development Kits (ADKs), and is excited about building scalable, production-grade AI platforms.

Responsibilities

• Agentic AI Development: Design, build, and deploy

agentic AI systems using frameworks such as LangChain, LangGraph, and related libraries. Develop and deploy

multi-agent systems capable of autonomous decision-making, reasoning, planning, and collaboration.

• RAG Pipelines: Implement and optimize

retrieval-augmented generation (RAG) systems, ensuring agents can access and incorporate external knowledge sources for

grounded, accurate responses .

• LLM Engineering: Fine-tune and prompt-engineer LLMs for

task-specific reasoning, planning, and dynamic adaptation . Work with

LLM/SLM APIs, embeddings, and advanced generative AI techniques .

• Enterprise AI Platform: Lead the development of enterprise-grade AI platforms integrating

LLMs, RAG, embeddings, and agentic AI protocols . Implement and standardize

Model Context Protocol (MCP) for consistent context management across models and agents.

• MLOps & Observability: Establish and enforce best practices for

MLOps, monitoring, and observability , ensuring scalable and maintainable AI solutions.

• Applied AI Prototyping: Rapidly

prototype, experiment, and iterate to improve AI agent capabilities.

• Collaboration & Research: Participate in the

full research cycle : literature review, data exploration, experimentation, and presentation of findings. Collaborate effectively with other engineers, researchers, and data scientists. Contribute to the

documentation and standardization of technical code and practices.

Required Education Bachelor’s degree in Computer Science, Engineering, or a related quantitative field.

Master’s or Ph.D. is a strong plus.

Required Experience

• Relevant experience Senior – Min 5+ yrs of relevance experience Intermediate – Min 3+ yrs of relevance experience Associate – Min 2+ yrs of relevant experience
• 1+ year of hands-on experience developing AI applications with LLMs and systems such as retrieval-based methods, fine-tuning, or agent-based architectures.
• 1+ year of experience with frameworks like LangChain, LlamaIndex, OpenAI, or similar tools.

Required Technical Skills

• Strong programming skills in Python and basics in SQL.
• Expertise with LLM/SLM APIs, embeddings, and RAG systems.
• Experience deploying on Google Cloud Platform (GCP) with Vertex AI, and IBM WatsonX.
• Familiarity with agentic AI protocols and exposure to Agent Development Kits (ADKs).

Preferred Qualifications

• Experience implementing Model Context Protocol (MCP) for agent coordination.
• Prior exposure to Lang Graph, AutoGen, or related orchestration frameworks.
• Knowledge of MLOps best practices (CI/CD for ML, observability, monitoring, scaling).
• Familiarity with responsible AI principles (safety, fairness, interpretability).
• Experience in enterprise-scale deployments of AI-driven platforms.
• Contributions to open-source AI/ML projects are a plus.
