About the Role
We’re looking for a Full-Stack Engineer (Backend-leaning) to design and build the systems and user-facing features that power Collate. You’ll spend most of your time on backend challenges—APIs, services, and infrastructure—but you’ll also ship end-to-end features.
This is an opportunity to help define our technical foundation, collaborate directly with design and product, and shape how our users experience Collate from day one.
Modern Tech Stack
