Raisin

Raisin operates a savings and investment marketplace that connects over one million customers with more than 300 partner banks across ten countries in Europe and the United States. Founded in 2012 and headquartered in Berlin, the platform has channeled upwards of €80 billion into competitive savings products. That kind of volume means the attack surface is real: customer identity data, financial transactions, and banking integrations spanning multiple regulatory jurisdictions.

The threat model here isn't theoretical. Raisin's platform sits between consumers and licensed financial institutions, handling sensitive personal and financial information at scale. Security teams operating in this space deal with cross-border compliance frameworks, API-level trust boundaries between partner banks, account takeover risks, and the constant pressure of fraud targeting financial marketplaces. The regulatory landscape alone - spanning EU financial directives and US banking requirements - demands rigorous controls around data protection, access management, and incident response.

For security engineers, the environment involves securing a high-throughput marketplace where availability and integrity aren't optional. The technical surface includes web application security, cloud infrastructure hardening, secure SDLC practices, and third-party risk management across hundreds of banking partners. If you're looking for a role where the stakes are measured in euros and regulatory filings rather than hypotheticals, this is that environment.
