Senior Software Engineer

ASK4 provides managed internet connectivity and smart building technology to multi-tenant properties across Europe. Our network platform underpins homes and workspaces for residents in student accommodation, build-to-rent, and multi-dwelling properties at scale.

As a Senior Software Engineer in our Network Systems team, you’ll design, build, and operate the software that keeps this platform running. From automation tooling and AI-powered network intelligence to provisioning and monitoring systems, your work will directly influence how reliably our services perform at scale.

You’ll bring independent technical judgement, contribute to architectural decisions, and play an active role in raising the capability of the team around you.
