Senior Fullstack Engineer

About the role

About Bree

Bree helps Canadians manage short-term cash gaps through interest-free loans. We’re building an alternative to traditional short-term credit: one that is cheaper, faster, easier to understand, and designed to help people when they need money most.

More than 800,000 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 by growing alongside our clients.

We are now entering a new stage of growth. We are expanding our product across Canada, adapting to new regulatory requirements, modernizing important parts of our platform, and building a stronger foundation for the next generation of Bree products.

Why Join Bree

Join us if you want to work on a product that makes a tangible difference in people’s lives. Customers come to Bree when access to money matters, so improving a bank connection, repayment flow, or support experience has a real human impact. You’ll have the ownership to shape those decisions, work closely with the people affected by them, and see what happens after you ship.

About the Role

We are looking for a Senior Fullstack Engineer to own meaningful product work from the initial customer problem through release and follow-up.

This is not a role where Product defines every requirement and Engineering takes over at implementation. You will work directly with Product, Design, CX, Operations, and other engineers to understand the problem, shape the solution, make technical decisions, and own the outcome after release.

A project might involve designing a new React Native experience, updating eligibility and product rules, introducing new APIs and database models, integrating with a payment provider, building internal tools for CX, and monitoring how the feature performs in production.

You will join a small engineering team working on a product with large scale, and with direct consequences for customers’ access to money.

Bree has grown quickly, and our codebase reflects that. Some areas are well established; others need careful modernisation. We’re looking for someone who can improve the foundations while continuing to ship reliable product changes for customers.

What You'll Do

- The full lifecycle of a feature, including discovery, technical design, implementation, testing, rollout, monitoring, and follow-up

- Work across our TypeScript and Node.js serverless backend, including Lambda, API Gateway, and SQS, as well as our React Native application

- Make practical architectural decisions about service boundaries, data ownership, and when to refactor versus extend an existing system.

- Instrument what you ship and hold the line on stability without slowing releases.

- Use tools such as Codex, Cursor and Claude Code to move faster while remaining responsible for correctness, testing, and quality.
