Senior Cloud Native Network Engineer

Description
Does running an ISP for IoT sound cool? What if we sprinkle in some telecommunication stuff running on K8s? Okay, that might still not be enough. What if the team also made an open-source version of the SIM running on software that we dubbed SoftSIM, which runs on a variety of modems so that users do not have to physically own a SIM card to connect to the network?

If you think any of this sounds remotely cool, stupid, or crazy, then you are the person Onomondo is looking for.
