Generative & Agentic AI

• Retrieval-Augmented Generation (RAG) — standard, graph-based, and vector DB–integrated (FAISS, Pinecone, Weaviate, Milvus)
• Multi-agent orchestration (LangGraph, AutoGen, Semantic Kernal, tool-calling with OpenAI function APIs)
• Fine-tuning diffusion & generative models (Stable Diffusion, Flux.1, ControlNet, DreamBooth)
• LLM fine-tuning (parameter-efficient methods: LoRA, QLoRA, adapters) on models like Llama3, Mistral, CodeLlama, Falcon, Gemma, Azure OpenAI models
• Advanced prompt engineering with context engineering(system prompting, function calling, safety alignment, guardrails)

Machine Learning & Deep Learning

• Classical ML: tree ensembles (XGBoost, LightGBM, CatBoost), linear/logistic regression, clustering (k-means, DBSCAN), dimensionality reduction (PCA, t-SNE, UMAP)
• Deep learning: CNNs (ResNet, EfficientNet), RNNs/LSTMs, GRUs, Transformer architectures (BERT, ViT, GPT)
• Graph ML: Graph Neural Networks (GNNs — GraphSAGE, GAT, PyTorch Geometric, DGL)
• Time Series: forecasting (Prophet, ARIMA, DeepAR, Temporal Fusion Transformer)
• Reinforcement Learning: RLHF, PPO, DQN, policy gradients

Optimization & Deployment

• Model optimization: TensorRT, ONNX Runtime, quantization (INT8, FP16, mixed precision), pruning, distillation
• Scalable deployment: Dockerized microservices, Kubernetes, REST/gRPC APIs, Azure functions.
• Cloud: Azure AI/ML services (App Service, Azure OpenAI, AML)
• Monitoring: Azure Monitor, Prometheus, Grafana, ELK stack for model drift.

About you:

• Master's or Bachelor's degree in Computer Science or related field
• 5+ years of experience in AI/ML with demonstrated end-to-end solution delivery
• Must have experience in Generative AI Projects
• Hands-on experience productionizing ML/LLM solutions (from PoC → scalable deployment → monitoring & maintenance)
• Strong foundation in ML/DL theory (optimization, loss functions, architectures)
• Demonstrated applied research/engineering — publications, open-source contributions, or patents are a plus
• Strong analytical, problem-solving, and debugging skills

Your career with us:
Working at Technip Energies is an inspiring journey, filled with groundbreaking projects and dynamic collaborations. Surrounded by diverse and talented individuals, you will feel welcomed, respected, and engaged. Enjoy a safe, caring environment where you can spark new ideas, reimagine the future, and lead change.
