Lead Product Designer

As a Lead Product Designer, you are a recognized design expert and the owner of the user experience for the Mirakl Platform back office. You apply your UX/UI expertise to make complex marketplace and e‑commerce concepts simple and intuitive, in close collaboration with our squads (user management, orders, catalog, pricing, after‑sales, accounting, etc.). You align design goals with business priorities and influence product decisions at the right level. You are not just a Figma producer — you are a true product builder who engages upstream of design, experiments fast, and delivers measurable value.

This job is based in Paris or Bordeaux with: 4 days worked onsite per week, 1 day worked remotely per week.

What you’ll do:

• Co‑develop — with the Design Director and Group Product Managers — the product vision and design strategy, and work with Product Designers to bring it to life.
• Build the product, not just design it: engage from problem definition, challenge assumptions, co‑create solutions, and measure their real impact.
• Structure and guarantee the coherence and quality of deliverables at every stage (benchmarking, user research, wireframes, high‑fidelity prototypes, specs, edge cases).
• Deliver measurable business impact by proposing effective, compelling, and innovative design solutions to complex business problems.
• Actively use AI tools in your day‑to‑day practice: Cursor, Claude Code, Figma AI, v0, Uizard, or any emerging tool — to prototype faster, explore more options, and ship better.
• Maintain an active watch on new tools, methods, and design & AI practices, and champion their adoption internally to evolve the team’s ways of working.
• Measure and analyze the adoption and usage of delivered solutions and propose iterative improvements based on user insights and product metrics.
• Embed co‑design in your practice and facilitate co‑creation workshops with cross‑functional teams.
• Contribute to and help govern the Design System (prioritization, contribution, versioning, design tokens) and champion its adoption across the organization.
• Represent design with key stakeholders (Leadership, Sales, Customer Success, Marketing), communicate progress, and arbitrate experience/tech/business trade‑offs when needed.

Qualifications:

• Seasoned expert: 6+ years of Product Design experience on complex B2B SaaS products — not necessarily a manager, but a true design authority with recognized seniority.
• Product builder at heart: you have a track record of shipped features or products with measurable impact. You think in terms of value delivered, not design deliverables.
• You master the end‑to‑end design process and bring user‑centered design methodologies (Design Thinking, Double Diamond, etc.) to the team’s daily practice.
• AI‑native practice: you actively use Claude Code, Cursor, Figma AI, v0 in your workflow, and keep pace with the market to identify the next tools.
• Beyond Figma: you operate upstream (strategy, discovery) and downstream (implementation, impact measurement) — not just mockup production.
• Entrepreneurial mindset: you take ownership of the product, work with passion, and consistently strive to exceed expectations.
• Excellent team spirit and open‑mindedness: you advocate for your ideas and challenge your own proposals.
• Fluent in French and English.
• You demonstrate humor, respect, and kindness.
