Description du poste

Cobl helps people produce high-quality documents by working with multiple AI agents they orchestrate directly. Users express what they need, agents handle the heavy lifting, and the user stays fully in control of structure, content, and formatting. The result is fast iteration, zero loss of information, and polished documents that stay faithful to the original intent. The experience is simple, reliable, and efficient: you direct the agents, they do the work, and you get a final document that is clean, accurate, and ready to use.

As our Product Designer, you will craft creative, and innovative interfaces for a product built around AI agents. UX and UI quality are central, since every screen must find the right balance between efficiency, clarity, and purity.

• You will work in ultra-fast iteration cycles. We gather feedback, prototype, ship, test, validate, refine, and release. Iteration loops last a few hours. It is live design.
• Explore and iterate quickly with the PM and the frontend team to validate ideas and ship improvements at high velocity.
• Design and refine interfaces that make complex AI interactions simple and intuitive.
• Maintain a high bar of execution with a strong attention to detail, UX and product coherence.
• Own the visual expression of the product, ensuring consistency, clarity, and creative ambition across all outputs.
• Strong prototyping skills and experience turning ideas into tangible user flows (Figma, vibe-coding tools, interactive prototypes, or comparable tools).
• Produce visuals for communication: content pieces, carousels, images, customer stories, feature announcements, and assets used for motion design in coordination with our motion designer and video maker.

Our design stack

• Lovable & v0 (open for other tools)
• Webflow

Who we’re looking for

• Fluent in English
• Passionate for beautiful products and an obsession for clean, efficient interfaces.
• A creative mind, capable of proposing ideas and pushing exploration.
• Comfortable with written communication.
• Curious, open-minded, and eager to learn.
• Have a strong knowledge of best-in-class UX and UI practices.
• Strong prototyping skills and experience turning ideas into tangible user flows (Figma, interactive prototypes, or comparable tools).
• Open to profiles with less experience if we see taste, creative spark, and a real obsession for great products.

What We Offer

• Permanent contract (CDI), work in Paris or remotely
• Join a startup backed by one of the leading VC funds in France, with a competitive salary and meaningful equity opportunities.
• Premium health insurance for you and your family
• Your choice of computer equipment
• Quarterly team weeks
• Work on a product used by major companies (61% weekly active users)
• A small, dedicated team of passionate people
• Help shape how businesses use AI in real situations

Our culture

At cobl, everyone owns their work. We value autonomy, execution, resourcefulness and craftsmanship. We focus on building something genuinely useful. We push for fast feedback, short cycles, and high standards. Simplicity, clarity, and well-made work guide everything we do.

Our hiring process

Our hiring process is simple and focused. You will start with a discovery call to understand the role, the team, and the product context. You will then meet the PM and members of the product team for a deeper discussion about your approach to UX/UI, iteration, and collaboration. The final step is a conversation with our CEO to align on vision, expectations, and culture.
