Senior Front-end Developer

Information Technology Toronto, Canada


The Freedom Network is a platform for distributing digital offers to shoppers, wherever they may be: at home, in store, or on the go.  Freedom engages tens of millions of shoppers, and the offers distributed through our platform have provided consumers with well over $10M in savings on groceries and staple items.


We’re looking for a Senior Frontend Developer to help us build the user-facing tools for our Freedom digital incentives network. In this role, you will be a senior contributor on a small cross-functional team that iteratively delivers value to our customers. This team is currently wholly responsible for the entire technology stack of our B2B product, and has full autonomy in the technical and architecture choices that it makes.


You will enjoy this role if you are someone who works well in teams and enjoys collaborating.  You will work directly with product managers, designers, and internal users to design features for the platform. You will also collaborate closely with the Director of Engineering for the Freedom platform to help evolve the frontend architecture of the Freedom platform.  Finally, you will be counted on by your teammates to provide guidance and mentorship as they develop the features on the platform.


Our software runs on Amazon Web Services.  Our frontend is built with React, Redux, and GraphQL, and there are some older pieces built in PHP. We build backend services with the PHP Phalcon Framework, MySQL, and AWS Lambda.   We ship code to production frequently, and typically release software once or twice a week. We have a reliable automated test suite, and in general it’s really easy to get things done.


We place a high value on people who have a deep understanding of software architecture and modern development practices, and who embody Checkout 51’s cultural values.
