About Bree

Bree is a consumer finance platform that brings better, faster, and cheaper financial services to over half the Canadian population who live paycheck to paycheck. We operate in a huge, but overlooked market in a country with the least amount of financial technology innovation in the developed world. Our first act is to become the cheapest and best provider of short-term credit to the 20 million people in Canada who live paycheck to paycheck.

More than 600,000 Canadians have already signed up with Bree and we believe we are just scratching the surface. We are in an exciting place where we have product market fit, explosive growth, and a clear path to becoming one of the most important FinTechs in Canada.

We are at 8-figures of annualized revenue, growing double-digit monthly, profitable, and have had zero voluntary employee churn. We were part of Y Combinator in 2021 and raised a $2M seed round shortly after.

• Collaborate with infrastructure engineers to optimize our AWS-based architecture using Infrastructure as Code.

• Drive the consolidation and standardization of our data layer across Supabase, Firebase, and legacy systems.

What You'll Need

• Expert-level proficiency in TypeScript/Node.js and serverless architectures, with deep AWS Lambda and event-driven systems experience.

• Demonstrated ability to leverage AI development tools to accelerate delivery while maintaining code quality and architectural integrity.

• Excellence in designing clean, testable, and well-documented code that serves as an effective context for AI assistants.

• Commitment to Bree's mission of providing Canadian consumers with the best short-term credit services.
