Aiphone is a global manufacturer of intercom and security communication systems used across enterprise, residential, healthcare, and government deployments, from IP video door stations and access control to large-scale emergency communication systems.
Beyond the hardware, Aiphone runs cloud platforms that let operators provision, monitor, and remotely manage on-site devices at enterprise scale, including a billing system for the SIM/eSIM connectivity that keeps cellular-enabled devices online. The engineering work spans AWS infrastructure, event-driven backend services, and integrations with on-site device firmware and external telecom providers.
