About Zeffy

⚡ Zeffy is the fastest-growing nonprofit platform in North America, helping organizations raise funds, run events, and engage donors. We are already working with more than 80,000 nonprofits and are doubling annually.

🌍 Millions of people dedicate their lives to causes beyond profit, running schools, shelters, and community initiatives. Yet most still lack modern tools. We believe the greatest opportunity for technology today is to amplify the impact of nonprofits.

🌱 Built on a sustainable, self-funded model, Zeffy reaches over 1M donors monthly and grows profitably, giving us the freedom to focus fully on our mission.

🫶 Nonprofit workers are heroes. They deserve the best technology, and we’re hiring top minds and top hearts to build it for them.

About the role

As our AI Growth Engineer, you'll be the architect of Zeffy's next growth chapter.

You'll design and ship the systems that power our entire growth engine, from enriching our understanding of the market, to finding and engaging new nonprofits, to activating and expanding the ones already using Zeffy.

This is a rare opportunity to build a function from scratch, experiment with cutting-edge AI tools, and watch your work directly transform how thousands of nonprofits fundraise.

What You'll Do

Build state of the art growth engine with AI, leveraging the millions of users on our platform.

Enrich Our Market Intelligence: Build systems that deepen our understanding of nonprofits: enriching lead data, uncovering market signals, and surfacing insights that sharpen our targeting and messaging.
Pioneer AI-Driven Acquisition at Scale: Design automated workflows that discover and engage nonprofits at scale. Experiment with LLMs to craft outreach that feels personal, and uncover opportunities before anyone else does.
Supercharge Product Activation & Expansion: Optimize the automated emails, SMS, and in-app triggers that turn new signups into active users and active users into power users. Your work will directly improve activation rates and drive cross-sell across our product suite.
Own the Growth Tech Stack: Connect the tools that power our growth into systems that deliver results and propose better solutions when you find them.
Instrument & Optimize: Build dashboards, run experiments, and continuously improve performance. You'll know what works because you'll measure it.

Why Growth Engineering matters at Zeffy

At Zeffy, growth isn't just about numbers. It's about reaching the nonprofits who need us most but don't know we exist yet.

Growth as Mission Multiplier: Every nonprofit we reach is another organization that can put 100% of donations toward their cause. Your automation directly amplifies social impact.
Growth at Scale: Millions of nonprofits across North America are still paying unnecessary fees or using outdated tools. The systems you build will help us reach them.
Growth Through Innovation: We're building at the frontier of AI and automation. You'll experiment with tools and approaches that most companies haven't discovered yet—and shape how our industry thinks about growth engineering.

Preferred experience (qualifications)

You've built automation that solved real problems (the tools matter less than the results)

You don't need to know every tool we use. What matters is that you're the kind of person who learns by building through documentation, YouTube tutorials, Claude, and trial-and-error. Some of the best GTM engineers come from RevOps, agency life, product design, or even teaching. If you've taught yourself to automate things and you're hungry to do more, we want to hear from you.

💡 Research shows that candidates from underrepresented backgrounds often don't apply for roles if they don't check every box. If this applies to you and you are interested in the position, we'd love to hear from you!
