POSITION OVERVIEW We are looking for a Senior Backend Engineer to join our team. You will shape the design and architecture of our products and work closely with the founding team, who built and scaled products at Revolut, Square, and SumUp, to deliver 10x value to our clients.

You will ship code frequently, iterate quickly based on feedback, and still meet the stringent security, performance, and uptime requirements our clients expect.
