Senior Backend Engineer

Two hours on a payments system as it grows: fix a production incident, make a slow report correct and fast at real volume, then build a product change and design for a scale scenario revealed partway through. Reviewed like a pull request at a top engineering company.

Tell us about your work. It takes about 10 minutes and a person reads every application we shortlist. If it's a fit, we'll invite you to our practical assessment (the Lab): two hours on a payments system as it grows, in a private GitHub repository, with AI tools allowed.

We're not actively recruiting right now, but you can still apply. We keep every application, and when we need someone we send the link to our practical assessment straight to the people who fit.
