This is a primarily back-end role (~70%) where you will develop TypeScript services that power subscription management, billing workflows, and merchant-facing APIs used by Shopify stores processing millions of transactions. 

You will independently deliver features as part of a team, proposing and agreeing the approach with an experienced team lead, implementing the solution, and monitoring and operating it in production. These systems need to be reliable, observable, maintainable, and performant.

You will effectively use AI agents such as Claude code and Codex to deliver at pace.

You will also contribute to our React-based front-ends (~30%) when delivering features as part of an experienced multi-functional team.
