Fullstack Engineer – Intern

honei connects payments, cash management, and data so restaurant groups can operate with full control at every location. Integrated payments. Automated closings. Zero discrepancies. Instant reconciliation. Real-time visibility.

Every payment also generates customer insights so teams know how to engage with each guest. No forms. No apps. It reflects what customers actually do — not just the 5% who sign up for loyalty programs, but the full 100%. No opinions. No guesswork. Because the data comes from the payment, not from a form.

More than 300 restaurant brands in Spain already operate with honei, including Grupo Azotea, Grupo Arzábal, Familia La Ancha, Comess Group, and Pastelería Mallorca.
