Relational builds loan and debt management software for financial services, with three core products (i-Apply, CiTRON, AroTRON) backed by 30 years of domain expertise. The tech stack is mature enterprise-grade (.NET, C#, SQL Server, Kubernetes, Docker) with observability depth (Prometheus, Grafana, Jaeger, OpenTelemetry), suggesting a focus on production stability in regulated environments. Current hiring is engineering-heavy and accelerating, concentrated in Greece, with a senior-skewed mix — consistent with the company's shift toward scaling their arrears management capabilities.
