Internships @ Wealthsimple

Location: Toronto, ON (Hybrid)

We offer 4-8 month internships designed for co-op students, non-co-op students, and recent graduates who are ready to ship impactful work. You'll join a high-performing team where you'll contribute to projects that are fundamentally changing how Canadians manage their money. We're committed to your growth, providing the mentorship and community you need to deepen your craft and leave better than you arrived.

Our internship program operates on a hybrid model out of our Toronto headquarters. You'll be in-office on Wednesdays and Thursdays to collaborate, connect, and learn in person, while maintaining the flexibility of remote work for the rest of the week.
