Skills you bring - 6+ years of experience in fraud prevention, including 3+ years working directly on card fraud (prepaid or credit) at an issuer, fintech or payments platform. - Hands-on ownership of card fraud strategy across application, transaction and account takeover fraud. - Advanced SQL.

Who you are - You set direction on your own and take ownership over outcomes for your space, from fighting fraud attacks to minimizing client friction. - You make decisions with numbers behind them, and you're honest about what the numbers can't tell you. - You lead through influence. You can get a roadmap conversation to go your way by rallying others around shared objectives. - You use AI to aide in your workflow, and know when to question it’s outputs - You share what you know, and you make the people around you sharper WHY WEALTHSIMPLE? 🌸 Top-tier health benefits and life insurance 📈 Long-term group savings with employer match, through Wealthsimple for Business 🌴 20 vacation days, 4 wellness days, and unlimited sick and mental health days per year* ✈️ 90 days away: work outside Canada for up to 90 days per year* 👥 Employee resource groups, including Rainbow (2SLGBTQ), Women of WS, and Black at WS 🌎 We are a hybrid team with over 1,500 employees across North America.
