Software Development London, England 51–200 employees Privately Held

InfoSum operates a decentralized data collaboration network built on Go, Python, Java, and cloud infrastructure (AWS, Azure, GCP), with Kafka and gRPC handling distributed messaging. The engineering-heavy hiring mix—11 of 13 open roles are engineering—combined with active projects around backend services and scalable performance suggests the company is addressing internal bottlenecks around handling high-load data operations, a critical friction point for a platform handling sensitive customer data across multiple cloud environments.
