We are looking for a versatile and hands-on AI Engineer / Developer to lead the development, deployment, and scaling of AI applications powered by large language models (LLMs) and related tooling. The ideal candidate combines strong software engineering fundamentals with a deep understanding of MLOps, LLMs, DevOps best practices, and GPU-based infrastructure. You'll play a pivotal role in shaping our clients AI stack-from prototype to production.

Key Responsibilities:

• Build and integrate AI-powered applications using LLMs, LangChain, and vector databases.
• Design and deploy scalable systems leveraging GPUs (on-premise or in the cloud).
• Collaborate with data scientists to transition models from research to production.
• Develop and manage CI/CD pipelines for AI workflows and AI APIs.
• Implement monitoring, logging, and observability for AI workloads (e.g., model drift, latency, resource consumption).
• Optimize model performance and cost-efficiency across inference endpoints.
• Ensure compliance with IT and security standards for model deployment and GPU workloads.

Required Skills & Experience:

• 3+ years of experience in software engineering, with hands-on exposure to AI/ML systems, web development, and building applications leveraging large language models (LLMs).
• Strong Python skills; experience with backend APIs (FastAPI, Flask) is a plus.
• Experience working with LLMs (OpenAI, Hugging Face Transformers, Anthropic, etc.).
• Hands-on with LangChain, vector stores (e.g., FAISS, Pinecone), and retrieval-augmented generation (RAG).
• Solid grasp of containerization and orchestration (Docker, Kubernetes).
• Familiarity with GPU infrastructure and deployment tools (e.g., NVIDIA Triton, CUDA, TensorRT).
• Proficient with cloud services (AWS, GCP, or Azure) and IaC (e.g., Terraform).
• Understanding of model lifecycle management and MLOps tooling (MLflow, Weights & Biases, etc.)
• Fluency in English & French
