Wealthsimple Technologies - Senior Software Developer, Edge
Requirements
• Be a part of our Canadian success story and help shape the financial future of millions. Read our Culture Manual and learn more about how we work. • 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. • Strong experience with GraphQL, including schema design and performance considerations • Familiarity in API design patterns across REST and GraphQL, with the ability to provide direction on how internal and client-facing APIs should evolve, what standards to adopt, and when to break from them • A track record of delivering technical work that spans multiple services, with the ability to coordinate dependencies and maintain momentum • Solid software development fundamentals, with experience building and maintaining production systems. Experience with Ruby or Node.js is a plus • Clear communication skills and a collaborative approach—you bring people along through documentation and genuine partnership • A pragmatic approach to technical decisions, balancing ideal solutions with shipping impact
Responsibilities
• Contribute to our GraphQL Federation migration, working with GraphQL Mesh and Hive Gateway to move services from schema stitching to a fully federated supergraph. • Build and improve automation tooling, including AI-assisted migration scripts, that accelerates schema transformations. • Partner with backend teams to help them adopt federation patterns and resolve technical blockers. • Improve gateway performance and observability, contributing to our shared GraphQL libraries. • Create documentation and share knowledge that helps product teams adopt patterns without needing specialized expertise. • Mentor junior team members and participate in code reviews that raise the bar for API quality.
