SII Group Romania Tech Stack

Software engineering and IT outsourcing for banking, aerospace, and biometric systems

IT Services and IT Consulting Bucharest, Romania 501–1,000 employees Founded 2009 Privately Held

SII Group Romania is a 650+ person software engineering and consulting firm anchored in legacy banking modernization and specialized verticals (aerospace, biometric identification). The tech stack—Java, Spring Boot, Kafka, Spark, Kubernetes—reflects a backend-heavy, distributed-systems posture suited to high-reliability domains. Engineering dominates hiring (63 of 90 active roles, concentrated in mid and senior levels), and the pain-point list (legacy application maintenance, cloud cost optimization, security compliance at scale) reveals a business stretched between keeping older systems stable and building new cloud-native infrastructure.
