About the role:
As a Senior Full Stack Engineer, you’ll lead the delivery of high impact product and platform work across the stack. We’re looking for someone with strong ownership, sharp product instinct, and the ability to use modern AI tooling to meaningfully amplify their output. This is a role for someone who goes beyond execution, quickly gets to the heart of the problem, challenges assumptions where needed, and delivers practical, high quality solutions with real impact.
In this role, you’ll work hands-on across frontend and backend systems, help shape technical direction, and partner closely with product and design to build fast, pragmatic, high quality software at scale. You’ll also lead the design, architecture, and delivery of production ready AI applications at scale.
Hours of Work: Your core working hours will generally align with Eastern and Pacific time zones. However, as you'll also require partnering with colleagues across APAC occasionally, some flexibility will be required to enable effective global collaboration. We believe flexibility goes both ways, so you'll have the autonomy to structure your day in a way that balances collaboration, deep focus, and personal commitments.
Role Location: We welcome candidates with authorization to work in Toronto, Canada or British Columbia.
Hybrid Work Environment: This role is primarily remote, with access to our downtown Toronto office for collaboration, team meetings, and company events.

Collaborating with engineers and other cross functional team members to design functional, cohesive solutions that ship valuable features at scale
Designing, building, and maintaining APIs, services, and user facing application features
Integrating data from various backend services, systems, and databases
Compiling and analyzing data, processes, and code to troubleshoot problems and identify areas for improvement
Participating in research, producing POCs, and evaluating new methodologies and technologies that improve quality, reliability, scalability, security, and performance
Actively participating in code reviews by providing constructive comments and sharing and adopting best practices to improve codebase quality, efficiency, and security
Writing and maintaining software documentation where needed
Optimizing the application for maximum speed, scalability, and maintainability
Helping shape the technical direction of full stack development
