Base pay range

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 a Fraud & Risk Specialist at Zeffy, you'll play a critical role in protecting our platform and users as we scale across North America and expand into new markets like the UK.

Our challenge: As our products and payment operations expand, new fraud patterns appear and fraudsters constantly push the limits of our defenses. Your mission is to tackle anti-fraud daily operations (70%) while cracking the operational load and finding the big, radical solutions (30%) that cut fraud detection time in half.

Over The Past Few Months, Our Fraud Team Has

• Kept fraud losses around 1% of margin, striking the perfect balance between strong protection and healthy growth.
• Increased user satisfaction with fraud verifications by 10 points, reaching top-tier market standards.
• Fully automated nonprofit background checks using AI-driven workflows, speeding up onboarding and compliance.
• Streamlined payment dispute handling, cutting processing time by 3× through smart automation.

What Creates Value In This Role

• Detecting new fraud patterns – Hawk-eye vigilance to spot emerging fraud types and uncover sophisticated schemes (including the wildly creative ones you'd never expect) before they scale.
• Optimizing fraud operations – Identifying inefficient controls with low ROI and replacing them with high-impact alternatives through automation, streamlined processes or elimination of unnecessary work through radical simplification.
• Improving customer experience – Better communication, product improvements, and proactive measures that balance security with user satisfaction (e.g., ringless call on bank account changes).

Fraud & Risk Principles At Zeffy

• Fast decisions, faster implementation: We're a very small team, which means rapid decision and implementation cycles.
• Full-stack mindset: We split our time between solving daily fraud cases and building smarter, more automated systems.
• 80/20 obsession: We optimize for impact over effort. We're not looking for perfection in solutions – we're looking for the 20% of work that delivers 80% of the results.
• Carte blanche to innovate: We start from a healthy, functional baseline. You have full autonomy to optimize and innovate – scoring models, AI automation, new detection patterns. You hold the cards to create your own ideal working situation.
• Impact > hierarchy: The best idea wins, no matter who it comes from. If you have the better solution, you'll be given resources to implement it.

Preferred Experience (qualifications)

We're looking for someone with 0-2 years of experience in operations, back-office functions, or customer-facing roles, ideally in a startup, fintech, or payment company. We move fast by keeping things simple, and we want someone who shares that mindset.

• You bring judgment through your analytical mindset – attention to detail, investigative approach, ability to detect complex fraud patterns and dig until you find root causes.
• You're an empathetic communicator with strong client focus, clear communication in French and English, and ability to build trust while handling sensitive cases.
• You have an operational hacker mindset, improving efficiency, automating workflows, and generating creative solutions.
