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 Le Chat
We’re building a world-class AI assistant. From personal productivity to teams using it in enterprises, Le Chat should be powerful but simple to use. It lives across web, mobile, and more, adapting seamlessly to how people work and create.
What you will do
• Design end-to-end experiences for Le Chat, 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.
