Join our Series A startup as a Senior Product Designer and help build the AI-powered operating system for nonprofits!

We’re looking for a brilliant, user-obsessed Product Designer to help nonprofits access more funding and spend less time on admin.

Your first focus will be Grant Finder: an AI-powered product helping nonprofits find relevant grants, understand their eligibility and move confidently towards applying. From there, you’ll help us build Goodstack’s wider operating system for nonprofits.

You’ll work closely with Product, Engineering and AI to make complicated processes feel simple, intuitive and trustworthy. This is a hands-on role for someone who loves solving real problems and cares deeply about craft.

As Senior Product Designer, your mission will be to:

• Own the design of Grant Finder from discovery through to launch and iteration.
• Help shape Goodstack’s AI-powered operating system for nonprofits.
• Design AI experiences that feel intuitive, transparent, and useful.
• Speak with nonprofits, test ideas, and turn insights into better products.
• Partner closely with Product, Engineering, and AI.
• Turn complex funding journeys and data into simple, polished experiences.
• Evolve our design system as the platform grows.

After 3 months, success will look like:

• You understand our nonprofit users and the challenges they face accessing funding.
• You’ve shipped meaningful improvements to Grant Finder.
• You’ve helped define how Grant Finder fits into our wider nonprofit platform.
• Research and testing are regularly shaping product decisions.
• You’re a trusted voice on user needs, AI experiences, and product quality.

This role is a perfect match for you if you have:

• 5+ years of product design experience in fast-moving teams.
• A strong portfolio showing complex problems made beautifully simple.
• Excellent interaction, visual, and systems-design skills.
• Experience designing AI-powered, data-rich, or workflow products.
• Strong research, prototyping and testing skills.
• Confidence working in Figma and with design systems.
• A collaborative style and experience partnering with Product and Engineering.
• Comfort working with ambiguity and shaping products from an early stage.

Bonus if you have knowledge or love of:

• Nonprofits, grants, fundraising or mission-driven technology.
• AI-native products, recommendation tools or agentic workflows.
• B2B platforms, operating systems or multi-user products.
• Early-stage or scale-up environments.
• Building technology that creates meaningful social impact.
