Why this role matters

We’re assembling our founding design team to shape how people use AI for the next decade. At Mistral, we’re not just designing products—we’re designing for positive outcomes, building AI that feels human, intuitive, and delightful. If you’re a designer at heart—independent, craft-obsessed, and excited to define the future of AI—let’s talk.

About AI Studio

Mistral Code is the best way to code with AI. We’re here to make developers extraordinarily productive, allowing them to delegate coding tasks and focus on higher-level thinking. Imagine an AI that doesn’t just assist, but collaborates—understanding workflows, adapting to needs, and executing tasks with precision.

What you will do

• Design end-to-end experiences for Mistral Code, from onboarding to advanced features.
• Prototype, iterate, and ship—fast. You’ll be hands‑on, turning ideas into tangible experiences.
• Collaborate deeply with research, engineering, and product teams. Clear communication and a low ego are key.
• Contribute to our design system, ensuring consistency and craft (including motion design) across Mistral’s products.

You're a great fit if

• ✔ You have 7+ years of product design experience, with a portfolio that shows explorations and delivered work. Experience with consumer‑facing products (especially AI, chat, or social) is a plus.
• ✔ You’re obsessed with craft—visual, interaction, and motion design. You know that great design is invisible until it’s missed.
• ✔ You’re fluent in Figma, prototyping tools, and user‑centered design, but more importantly, you know how to use them to solve real problems.
• ✔ You’re independent and resourceful, with a bias toward action.
• ✔ You’re a self‑starter—results‑oriented, resourceful, innovative, intellectually curious, and willing to take initiative and risks.
• ✔ You’re highly collaborative, able to balance multiple projects and stakeholders.
• ✔ You’re professional, accountable, and driven, with a relentless focus on impact.
• ✔ You’re target‑driven, detail‑oriented, and approachable, able to prioritize and work well in an environment with competing demands.
• ✔ Bonus: Experience with AI prototyping (e.g., building interactive demos for LLMs or AI tools).

Why Mistral?

• Founding team: This is your chance to help build the design culture and processes that will define Mistral for years to come.
• Designing for good: Your work will shape how the world interacts with AI, focusing on positive outcomes.
• Zero‑to‑one impact: You’ll design products from scratch, not just features.
• Builder energy: We’re all builders at heart, more interested in making the best experiences than politics.

Hiring Process

• Recruiter's screen
• Portfolio review: Show us explorations and delivered work—we care about how you think, not just how it looks.
• Take‑home challenge: A product‑focused exercise to see how you tackle problems.
• Team Interview: Chat with Design, Engineering, and Leadership. We’re looking for collaborators, not egos.
• Culture fit: We want people who want to be here—who see Mistral as more than a job, but as a place to do their best work.
