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
