Your mission

At Telio, we build technology that reconnects people.

Our systems enable hundreds of thousands of inmates to stay connected with their families and loved ones. We believe correctional facilities should not only serve as punishment, but also as an opportunity for rehabilitation and a second chance. Through secure communication technology, digital services, and modern software platforms, we elevate the professional and human standards of correctional institutions and other regulated environments (e.g., clinics and state institutions).

This is a mission-critical internal product environment where reliability, security, and engineering excellence directly impact real lives.

We are looking for a skilled Network Engineer to ensure the stability, performance, and security of our on‑premise, cloud, and Kubernetes network environments. You will play a key operational role, working closely with international teams to support modern, hybrid infrastructure and continuously improve network operations.
