About Zeffy

🌬 We are leading a transformation in the social economy with our unique zero-fee fundraising platform. Our mission at Zeffy is to create technologies that empower nonprofits to change the world.

🚀 We are at an exciting stage of our journey. We support 50,000+ non profits and we have helped them raise nearly $1 billion without fee. With 200% year-over-year growth, we aim to support more than 350,000 nonprofits by the end of 2026.

🌱 Zeffy is a B-Corp company with a dedicated team and ambitious goals. We’re here to make a difference, driven by the will to create a better world.

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 to convert them into active users.
• Conversion on payment forms: With 600,000 monthly payments and $80M 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 to 50,000 active users, 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 lead the charge in making our platform more intuitive and enjoyable for nonprofits. Working closely with the product team and cofounders, you’ll turn user challenges into simple, effective solutions that enhance the user experience, driving activation and engagement.

In this role, you’ll get to:

• Be expert in user research to really understand user needs.
• Design intuitive solutions aligned with our product vision, refining prototypes through user feedback.
• Establish UX/UI standards for consistent, high-quality design.
• Mentor other product designers to support their professional growth (Problem understanding, user research, prototyping, UI/UX and Collaboration).

🚫 What you won’t be doing:

• Pixel pushing without purpose: Every design choice at Zeffy has a direct impact on our users. You won’t be creating unnecessary visuals without understanding the problem first.
• Designing without feedback and collaboration: You’ll work closely with teams and users to create solutions that truly work.

Preferred experience (qualifications)

• 8+ years of product design experience, with a background in fast-growing startups or working on products with large-scale impact.
• Experience leading design projects end-to-end, turning complex problems into simple and enjoyable solutions: be ready to share your portfolio!
• Proven track record of working efficiently across teams, managing challenging trade-offs, and delivering impactful product design solutions that drive business results.
• 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 design standards.
• Mentoring experience, helping junior designers grow and develop their skills.
