(Senior) Software Engineer - Backend - Growth *EU/UK remote* (m/f/d)

ABOUT US

The company is a modular B2B payments platform that combines commercial card issuing, payment accounts, FX, and spend management in one system — adapting to existing setups rather than requiring customers to replace them.

Businesses across industries such as travel, e-commerce, and insurance use the company to manage complex payment workflows with cards, backed by credit lines the company underwrites itself.

Fintechs and software platforms embed the company's payment infrastructure into their own products, from API-based Cards-as-a-Service to fully white-label solutions. Banks use the company's Card & Spend OS, the customer-facing interface, on their own infrastructure to run card programs.

Founded in 2020 and headquartered in Berlin, the company serves 5,000+ businesses and 40+ partners across Europe and the United States. A principal member of Visa and Mastercard, the company issues commercial cards in 13 currencies across 32 countries — under its own European e-money license and with licensed partners in the UK and US.
