You'll shape financial processors, build reconciliation flows, and develop the dashboards that give our finance teams real clarity and control. Your decisions will directly influence how the business operates and scales.

Beyond the code, you'll be a key voice on the team - contributing ideas, challenging assumptions, and helping shape what gets built and why.
