Résumé du poste

Arlequin seeks the first designer to build the design function from scratch, setting a premium visual language and a scalable design system for dense data interfaces. You will translate the founders’ product vision into cohesive UX while partnering closely with the CEO and future Head of Product.

Expect to shape design across data-heavy dashboards, ensure clarity for non-technical users, and elevate the product’s finish with strong typography and brand identity. On-site in Paris.

Qualifications

• 6+ years in product design / art direction, including significant work on digital products (SaaS, platforms, tools).
• A portfolio with a strong identity, attention to detail, interfaces that stand out.
• Ability to conduct serious product UX in parallel: structuring journeys and making complexity readable.
• Design system experience: knowing how to create one from scratch and get developers to adopt it.
• Comfortable in early stage: autonomous, pragmatic, able to create the framework instead of waiting for it.
• Professional French and English.

Responsabilités

• Create the design function from scratch and establish art direction as the product's premium visual language.
• Define the visual language, the design system and how design works, in collaboration with the CEO and Head of Product.

About Arlequin

Arlequin is building the sovereign European alternative to Palantir: an AI platform capable of processing massive data volumes without bias, with high-impact use cases such as fighting disinformation. Founded in late 2024 by Hugo Micheron (researcher in geopolitics and systemic risk) and Antoine Jardin (CNRS research engineer).

The role

You’ll join Arlequin as the first designer to create the design function from scratch and give a technically remarkable product the visual identity it deserves. Your priority is art direction: translating the founders’ and product vision into a strong, coherent and premium visual language that becomes Arlequin’s signature. The terrain is demanding — our interfaces can handle dense data that must remain clear for the people operating it — so your aesthetic standards always come with rigorous product UX thinking. You’ll define the visual language, the design system and the way design works, in direct contact with the CEO and future Head of Product.
