Description du poste

About Zeffy

More power to the people changing the world. Nonprofits have an immense impact on the world. They feed communities, protect the planet, educate children, and fight for justice — but their tools are holding them back. That’s why we’re building the global infrastructure to help them reach their full potential.

At Zeffy, we’re building the technology they’ve been missing. Today, 100,000+ nonprofits use Zeffy worldwide, with more than 10 million people relying on it. Together, they’ve raised over $2B — and every dollar goes directly to their cause.

Strong profiles, driven by impact Zeffy is one of the fastest-growing startups in Canada and France. We’re a small, highly efficient team that builds fast and takes ownership. We hire selectively with high expectations and real autonomy. Everyone is hands-on, and decisions are made quickly, without layers or unnecessary processes.

If this resonates, let’s meet.

About the role

As an Operations 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.

The 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 (50%) while cracking the operational load and find the big, radical solutions (50%) that cut fraud management 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.

Operations 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.

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 have an investigative analytical mind. You’re not satisfied until things add up. You’ve worked with data — spreadsheets, SQL, BI tools, or anything in between — and you know how to spot anomalies, build logic, and dig until you find root causes. You don’t need someone to hand you the answer. 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. When you see a repetitive task, your first instinct is to fix it — not just flag it. You’ve used automation tools, written scripts, or built workflows to cut waste. Bonus if you’ve worked with Python or no-code automation tools (Claude Cowork/skills, n8n, Make, Zapier, etc.).
