The Vacancy
If you want to work on infrastructure that matters — software that keeps tens of thousands of people connected every day — this is the role for you.
About the Role
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.
Key Responsibilities:
- Design, build, and maintain back-end systems supporting ASK4's network infrastructure — including provisioning, monitoring, and automation tooling
- Take end-to-end technical ownership of significant workstreams, from requirements and design through to production deployment
- Contribute to and drive architectural decisions, including technology selection, service decomposition, and integration patterns
- Build and maintain CI/CD pipelines, Helm charts, and Kubernetes configurations for production and non-production environments
- Integrate with network management systems, message brokers, and third-party APIs
- Instrument and monitor applications using observability tooling (metrics, logs, and traces — Grafana, Prometheus, or similar)
- Provide technical mentorship to mid-level engineers and act as an escalation point for complex problems
- Contribute to development standards, code review practices, and shared tooling across the engineering teams
