IT Services and IT Consulting London, England 51–200 employees Founded 2015 Privately Held

Saragossa is a London-based technology services firm focused on investment and fintech businesses, built on a polyglot stack heavy in Java, Python, Kafka, and cloud infrastructure (GCP, AWS, Azure). The engineering-led hiring mix—82 open engineering roles across senior and mid-level—paired with active projects in trading systems, private equity data platforms, and LLM agents for healthcare revenue cycle work, signals deep involvement in complex backend transformation rather than staff augmentation alone. Current adoption of Azure and AWS alongside Fabric and Python indicates a pivot toward modern data analytics infrastructure.
