Principal Product Designer

Who we are

Paris 🇫🇷 (EUR 75,000 to EUR 90,000) + stock options 💰 8+ years experience 🧪

🌬 Zeffy is leading a transformation in the social economy with its unique zero-fee fundraising platform, currently trusted by over 50,000 nonprofits throughout North America.

🚀 Experiencing a 300% year-over-year growth, we’re just getting started! There’s no better time to join us, as you’ll be among the first 40 employees set to make a tangible impact from day one.

🌱 If that’s not compelling enough for you, we are also proud to hold a B Corp certification.

 

Why Product Design matters:

As Zeffy is entirely product-led (we have no sales), user experience is key to our growth:

• Self-serve activation: Over 10,000 new accounts created by organizations every month. Every step matters.

• Conversion on payment forms: With 500,000 monthly visitors and $60M processed monthly, better design directly means more funds for nonprofits.

• Revenue model: Entirely based on voluntary contributions. Exceptional design can completely change the game.

• Product Led Adoption: To maximize our impact, the product must remain simple and intuitive, even as it grows more powerful and feature-rich—a true design challenge.

About the role:

As a Principal Product Designer, you’ll have to be the leader in making our platform even more intuitive and enjoyable for nonprofits. You’ll work closely with the product team and cofounders to turn user challenges into simple and effective solutions.

Preferred experience (qualifications)

• 8+ years of UX/UI design experience with a strong portfolio that shows a strong potential for simplifying very complex problems into easy and delightful solutions.
• Proven ability to lead design projects from concept to execution, solving complex problems implying difficult trade-offs (UX. business viability, legal risks, etc.)
• Strong collaboration skills and experience working with cross-functional teams.
• Expert in design tools like Figma, with a solid understanding of prototyping and user testing.
• Ability to lead by influence and inspire the whole design team to aim for exceptional designs standards
