Senior Product Designer

About the role

Overflow is a Series B Silicon Valley technology company with a bold mission: to inspire the world to give. We are a B2B SaaS philanthropy platform that enables modern giving across cash, stock, and crypto for nonprofits, churches, and mission-driven organizations. Backed by leading investors including Uncork Capital, Craft Ventures, and Village Global, Overflow builds secure, beautifully designed infrastructure that powers generosity at scale. Our Founding Principles Overflow was founded on the belief that generosity transforms people and communities. Inspired by Proverbs 11:24 - "The world of the generous gets larger and larger" - we operate with integrity, stewardship, service, and excellence. How We Work Overflow operates with a flexible work model. While there is no company-wide in-office requirement, some teams may establish in-person collaboration rhythms based on their function, goals, and team needs. We maintain offices in Los Gatos, CA and Birmingham, AL for team collaboration, coworking, meetings, and intentional in-person connection. We're hiring a Senior Product Designer to take end-to-end ownership of core areas of the Overflow product, including giving flows, the Tap product-led growth motion, payment experiences, and the client dashboard and reporting. You'll join a small, senior design team - as our third product designer - and partner daily with engineering and product to turn complex financial workflows into experiences that feel simple, trustworthy, and even delightful. This is a builder's role, not a handoff role. You'll move fluidly between strategy, prototyping, and pixel-level polish, and help shape the systems, processes, and quality bar for how design works at Overflow as we scale. You'll report directly to the Head of Product and have an outsized voice on product direction.
