Your Mission

As Product Designer, you will own the full design cycle: from deep research and ideation to delivery with engineers—always in close partnership with Product Management. The Designer/PM duo is central in shaping problems, defining success metrics, and ensuring that every solution is aligned with business impact and user needs.

How We Work

Collaboration and continuous improvement sit at the core of our team practices. Designers engage directly with product managers, engineers, and customer success, contributing from the earliest stages of product definition through delivery.
Our pragmatic approach ensures rigorous validation and a fast learning loop for everyone.

Responsibilities

• Work hand-in-hand with the Product Manager to identify, frame, and solve problems that matter. Share end-to-end ownership: research, flows, wireframes, prototypes, and deployment.

• Lead user research and customer journey analysis: challenge existing solutions, capture expected improvements, and proactively shape what can be brought to users aligned with company direction.

• Drive data-driven design: demonstrate deep reasoning skills grounded in both qualitative and quantitative data. Define relevant metrics, conduct research, validate design impact, and iterate using analytics and user insights.

• Apply “design to cost”: adapt solutions to ambition, scope, and business appetite so we deliver value at the right pace.

• Leverage AI design tools in daily workflows to accelerate creation, insight generation, and documentation.

• Design for industry: address complex, operational B2B challenges and workflows found in manufacturing customers.

• The voice of Design: develop, maintain and evolve our design system, ensuring UI/UX excellence and consistency.

• Foster team culture: work closely with both business & engineering teams to provide and receive feedback on ongoing projects.

What We’re Looking For

• 4+ years designing SaaS products, ideally B2B in the industry sector, with portfolio evidence.

• Strong experience collaborating with Product Managers and developers in fast-paced startup/scale-up environments.

• Advanced proficiency in Figma (required) and demonstrable experience integrating AI tools in design processes.

• Data-driven reasoning, leveraging both qualitative and quantitative research for impactful design decisions.

• Demonstrated success adapting solutions to constraints (“design to cost”), with a pragmatic and iterative mindset.

• Autonomous, rigorous, humble, and equipped with strong communication skills.

• Fluency in both French and English.

• Initial conversation with Founder CPO and Head of Product & Engineering

• Interview + use case exercise with Head of P&E and Product Manager

• Team fit round

• Reference calls

• Final interview with Founder CEO
