Open-Source AI · Paris
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.
Role Summary
We are seeking an Applied AI, Forward Deployed Engineer to build customer use cases on top of the Mistral stack. You will turn "we have agents" into "we shipped something a client uses." This role is about composing cybersecurity-related agentic workflows, configuring harnesses for real-world scenarios, and delivering value directly to clients.
As a Forward Deployed Engineer at Mistral, you may also work on use cases outside cybersecurity, bringing the same context engineering, orchestration, and eval work to enterprise workflows in finance, manufacturing, defense, or the public sector.
What You Will Do
- Client-Facing Agentic Solutions
- You'll individually help deploy into production use cases with considerable business impact across various industries, with cybersecurity client assignments as a priority
- You'll work on state-of-the-art GenAI applications, driving a crucial technological transformation together with our customers
- Tackle iconic use cases that no existing solution on the market can address - from custom configuration of cybersecurity harnesses for cloud defense, to optimizing agentic vulnerability scanning solutions, to customizing agentic red-teaming solutions or penetration testing scenarios
- You'll work directly on client use cases, translating security requirements into agentic solutions
- You'll be involved in pre-sales calls to understand potential clients' needs, challenges, and aspirations, providing technical guidance on our products and explaining Mistral technologies to various stakeholders
- You'll collaborate with our product and science teams to continuously improve our product and model capabilities based on customer feedback
How We Work in Applied AI
- We care about people and outputs
- What matters is what you ship, not the time you spend on it
- Bureaucracy is where urgency goes to vanish. You talk to whoever you need to talk to. The best idea wins, whether it comes from a principal engineer or someone in their first week
- Always ask why. The best solutions come from deep understanding, not from copying what worked before
- We say what we mean. Feedback is direct, timely, and given because we care
- No politics. Low ego, high standards
- We embrace an unstructured environment and find joy in it
About You
- You are fluent in English
- You have 2+ years as a technical individual contributor (data scientist or software engineer) on AI-based products
- You have proven experience in AI or machine learning product implementation with APIs, back-end, and front-end interfaces
- You have experience tackling advanced RAG, building agentic use cases, or fine-tuning LLMs
- You have a deep understanding of the concepts and algorithms underlying machine learning and LLMs
- You have strong technical coding skills in Python
- You have strong communication skills, with an ability to explain complex technical concepts in simple terms to both technical and non-technical audiences
Ideally, you have:
- Contributed to open-source projects, in particular in the space of LLMs
- Experience as a Customer Engineer, Forward Deployed Engineer, Sales Engineer, Solutions Architect, or Technical Product Manager
- Hands-on experience building agents, LLM orchestration, context engineering, evals, and RAG systems
- A bias toward action and delivery - you ship fast
- The ability to operate independently with a customer-led mindset
- The ability to reuse internal building blocks and components effectively
- Strong problem-solving abilities and attention to detail
- A collaborative attitude
- Pentesting knowledge
- Experience developing a cybersecurity product
- Experience building agentic harnesses or multi-agent systems end-to-end
