SBAB Tech Stack

Digital-first bank for Swedish home loans and savings

Banking Solna 501–1,000 employees Founded 1985 Public Company

SBAB is a state-owned Swedish bank operating entirely via phone and web since 1996, offering loans and savings products to individuals, housing cooperatives, and businesses. The tech stack—Python, Java, Kotlin, React, TypeScript, Kafka, and AWS—reflects a modern polyglot architecture built for digital-first operations. Heavy hiring in engineering and data roles around risk modeling, security, and cloud migration signals an active overhaul: replacing legacy infrastructure with cloud-native systems (AWS adoption), overhauling risk governance frameworks (PD/LGD models, compliance), and hardening identity and incident detection.

About SBAB

SBAB was established in 1985 as a state-owned institution and is wholly owned by the Swedish state. Since shifting to a digital-only model in 1996, the bank operates without physical branches, serving residential mortgages, tenant-owner association loans, savings accounts, and small-business lending through online and phone channels. The company maintains offices across Sweden—Solna (headquarters), Stockholm, Gothenburg, Karlstad, and Malmö—and employs 501–1,000 people. The current operational focus centers on modernizing risk infrastructure, securing external API integrations (PSD2/PSD3), and migrating legacy data systems to cloud environments.
