European payments infrastructure and fraud solutions at scale

Financial Services Alfragide, Lisbon 1,001–5,000 employees Founded 1983 Privately Held

SIBS operates a multi-layered payments ecosystem across Europe and Africa—processing billions of transactions annually through ATM networks, card terminals, and digital channels—built on a Java/Kafka/Kubernetes stack typical of large financial infrastructure. Active hiring in engineering and security, combined with projects spanning cloud-native payment solutions, AI/MLOps standards, and EU data protection mandates, signals infrastructure modernization and regulatory adaptation rather than core product pivots.
