CSU Digital Tech Stack

Financial services platform for payments, credit, and customer loyalty in Brazil

IT Services and IT Consulting Barueri, São Paulo 5,001–10,000 employees Founded 1992 Public Company

CSU Digital operates a mature financial-services infrastructure stack—Java, Spring, Kafka, Oracle, SQL Server—serving Brazilian credit card programs and electronic payment networks. The tech shape (message queues + relational databases + Kubernetes/AWS deployment) reflects a legacy-to-cloud migration in motion; hiring signals a leveling-up of engineering velocity (5 engineers hired recently) and internal compliance work (occupational risk, mental health, NR-1 compliance projects), suggesting the company is threading operational modernization alongside client-facing platform evolution.
