Job Description

Build something people love
Wealthsimple is on a mission to help everyone achieve financial freedom by reimagining what it means to manage your money. Using smart technology, we take financial services that are often confusing and expensive and make them transparent and low-cost for everyone. We’re the largest fintech company in Canada, with 3+ million users who trust us with more than $100 billion in assets. And we’re just getting started.

We’re looking for a someone who thinks big, sweats the small stuff and keeps things simple. You’ll join a high-bar, fast-paced team where people are trusted to own their work, communicate openly, and ship things that improve our clients’ lives. Collaboration, humility, and an obsession over quality are how we get stuff done.

The Edge team sits at the intersection of Wealthsimple's backend ecosystem and our client applications. We own the GraphQL gateway and the public API, along with the tooling, patterns, and best practices that help all our product developers ship features quickly and reliably. Reporting to a Senior Manager of Software Development, you'll work alongside developers and cross-functional partners to shape our APIs and how data flows through our systems. This year, we're leading Wealthsimple's migration from schema stitching to GraphQL Federation—a foundational shift that will make our gateway faster, more predictable, and essentially maintenance-free.

We're looking for a Sr Software Developer who can guide complex technical initiatives across the finish line while making other developers more effective. You'll help us implement our big project this year, GraphQL Federation architecture. We need someone who can lead delivery, partnering with teams across the company to migrate dozens of services to a federated model. You'll balance hands-on coding with technical leadership, unblocking teams, refining our approach as we learn, and ensuring we ship a gateway that product teams never have to think about.
