Koyeb and Mistral Cloud are high-performance, serverless platforms for deploying AI inference, APIs, databases, and resource-intensive applications across global infrastructure. We abstract away the complexity of Kubernetes, instance management, and multi-region deployments, so developers can focus on what matters: building and shipping fast. Your designs will bridge the gap between raw infrastructure and the polished, user-friendly workflows of Mistral Studio, enabling users to deploy, monitor, and scale AI with confidence.

• Design end-to-end experiences for cloud and infrastructure products, from onboarding to advanced workflows (e.g., Kubernetes cluster management, instance provisioning, autoscaling, and monitoring).

• Prototype, iterate, and ship-fast. Turn complex technical concepts into intuitive, elegant interfaces that feel inevitable.

• Collaborate deeply with engineering, product, and research teams to balance user needs with technical constraints.

• Contribute to our design system, ensuring consistency, accessibility, and craft (including motion and data visualization) across all Mistral products.

• Solve for scale: Design for both power users (DevOps, ML engineers) and newcomers, making infrastructure management approachable without sacrificing depth.

• Integrate your work into Mistral Studio, aligning infrastructure tools with our AI production platform to create a unified, powerful user journey.

• 7+ years of product design experience, with a portfolio showcasing complex, technical products (e.g., developer tools, cloud platforms, infrastructure, or AI workflows).
• AI-first designer: Comfortable vibe coding, building interactive prototypes, and even submitting PRs to ensure design quality and polish.
• Obsessed with craft-visual, interaction, and motion design. You sweat the details, from empty states to error handling.
• User-centered design. You care more about solving real problems than pixels.
• Independent, resourceful, and biased toward action. You thrive in ambiguous, fast-moving environments. You make things happen.
• Experience with:
  • Designing for developers, DevOps, or infrastructure teams (Kubernetes, Docker, CI/CD, or similar).
  • Data-heavy interfaces (dashboards, logs, metrics, or observability tools).
  • AI/ML workflows (model deployment, inference, or cloud services).
• Clear communicator with a low ego. You can explain technical trade-offs to non-technical stakeholders and advocate for users.

• Founding team: Help build the culture, processes, and design language that will define Mistral's infrastructure and Studio products for years.

• Designing for good: Shape how the world interacts with AI and cloud computing-focusing on sovereignty, transparency, and user empowerment.

• Zero-to-one impact: Design products from scratch, not incremental tweaks.

• Builder energy: We're all makers at heart, focused on shipping great experiences, not politics.
