About the Opportunity

On behalf of our client, a highly innovative Deep Tech startup, we are seeking a visionary Generative AI Software Engineer.

Our client is developing a disruptive, high-fidelity simulation software poised to revolutionize industries like Aerospace, Energy, and Weather Forecasting.

We develop a disruptive, scale‑resolved CFD software platform for industrial and environmental flows (e.g. aerospace, power generation, energy, weather forecasting), built for GPU and future Quantum Computing architectures. The long‑term vision is to combine this solver with advanced Generative AI interfaces to dramatically improve ease‑of‑use and engineering productivity.

You will drive a paradigm shift in human–computer interaction for complex engineering applications.

Your responsibilities will include:

• Design and develop the GenAI UI : Architect and implement the company’s new Generative‑AI‑powered User Interface, focusing on natural language interaction, ergonomics and intuitive man–machine interfaces.
• Build generative & agentic AI models : Develop Generative, Self‑Learning and Agentic AI models, leveraging modern LLM libraries and tools (e.g. Mistral, LangChain or similar), tightly integrated with the company’s simulation workflows.
• Core programming on GPU systems : Implement robust, high‑performance components in C, C++ and/or Python, with a strong focus on GPU‑native programming for interactive and computationally intensive features.
• Test, validate and communicate : Rigorously test and validate your developments, participate in scientific and technical conferences in the fields of CAE & AI, and contribute to documentation and scientific papers.
