Discovery Scientists, AI for Science

About Mistral

Mistral provides full-stack AI solutions: from frontier models to developer tools, applications, and compute. We partner with enterprises tackling the hardest problems—across high-stakes industries like finance, manufacturing, defense, healthcare, and the public sector—co-creating customized AI systems that they can run on their terms.

We are a dynamic, collaborative team passionate about AI and its potential to transform society. Our diverse workforce thrives in competitive environments and is committed to driving innovation. Our teams are distributed between Europe, North America, Asia and the Middle East. We are creative, low-ego and team-spirited.

About the Role

We are building a team of exceptional Discovery Scientists, who can identify and solve key problems in their respective fields, here in STEM, with a particular focus on Physics, Chemistry, and Material science. The idea is to leverage the cutting-edge capabilities in AI of our Core Science organization. You will be able to shape the mission and:

• Accelerate scientific discovery through high quality, open access research
• Be empowered with advanced AI tools, participate to improving these tools in STEM, and the freedom to explore high‑impact projects at the intersection of your domain and AI.
• Participate in the growth of fundamental and industrial applications in AI for science

Generally, our team will focus on two axis: (1) improving the models' capabilities in solving open science problems and (2) systematically accelerating simulations.

What you will do

• Identify and Define Impactful Problems: Proactively identify critical challenges in your field where AI/ML can drive breakthroughs.
• End-to-End Research Ownership: Lead independent research projects from ideation to implementation, including literature review, hypothesis formulation, numerical experimentation, and validation.
• Develop and Apply AI/ML Solutions: Design, implement, and refine advanced algorithms, models, and frameworks (e.g., deep learning, LLMs, agentic AI) to address domain-specific problems.
• Collaborate and Innovate: Work with a multidisciplinary team of scientists, engineers, and domain experts (including customers) to push the boundaries of what’s possible with AI in science.
• Autonomy and Initiative: Operate with high autonomy, setting your own research agenda and driving projects to completion with minimal oversight.

What We're Are Looking For

• Domain Expertise: Strong understanding and research capabilities in at least one scientific domain (e.g., physics, chemistry or materials science), demonstrated by first-author publications, open-source contributions, or other impactful projects.
• Track record in AI/ML; the ability to shed light on hard, real-life problems with an AI solution, demonstrated by further contributions.
• Broad experience in coding, for scientific computing and in machine learning, deep learning, and/or large language models.
• Hands‑on experience using frameworks like PyTorch or TensorFlow is especially appreciated.
• Interdisciplinarity: ability to communicate to a broad-non specialized audience while still remaining technical.
• Customer Collaboration Experience: Experience working with customers or end-users to refine requirements is also appreciated.
• Low ego and team spirit mindset
• Embraces hands‑on, operational work
