Software Engineer PHP H/F

[SKALEET]

Skaleet builds the core banking engine behind banks and neobanks: accounts, payments, cards. Our platform runs in production for 30+ regulated financial institutions in 15 countries, including Crédit Agricole, Caisse d'Epargne and Nirio (FDJ United), and manages over 10 million accounts.

In 2026, Euromoney named Skaleet the best banking solution in Europe. Our revenue grew by 40% in 2025. We are about 100 people, based in Boulogne-Billancourt.

Our ambition: become the platform of choice for European banks and fintechs that want to replace their legacy core banking systems.

💡 Context

As we support increasingly demanding Tier-1 financial institutions, we are strengthening our Software Factory to drive the evolution of our core banking platform.

As a PHP Software Engineer, you will join one of our product squads and build features of a modular banking platform running in production for banks and fintechs. Code quality, performance and system stability are fundamental requirements here, because these features carry real financial flows.

🤖 AI-driven development

At Skaleet, we develop our features with AI. Most of our developers are AI-driven, from design to development.

We expect you to be more than comfortable with AI: it will be part of your daily work as a developer.
