Uni Systems is a six-decade-old systems integrator and ICT services provider spanning 20+ countries with 1,800+ specialists. The tech stack—Java, Spring, Azure, Kafka, Elasticsearch—reflects a mature enterprise integration business. Active hiring acceleration (53 roles in 30 days, mostly senior engineering and security) combined with infrastructure-heavy projects (Kubernetes adoption, cloud migrations, cluster deployments) and pain points around legacy system modernization and knowledge management suggest the company is scaling engineering capacity to handle large-scale digital transformation contracts and cloud migrations for European enterprises.
