About the Project

Our client is an international cybersecurity software company that helps large organizations manage and protect their network environments. The company develops solutions that help businesses manage network security rules, control access, automate security processes, and reduce risks related to network infrastructure. They work with enterprise customers that often have large and complex IT environments, including multiple networks, firewalls, data centers, and cloud infrastructure. As a Network Engineer in the PS-DEV group, you will own the network and security devices that power our client's Open Model (OPM) activities. OPM extends the product suite to firewalls, micro-segmentation platforms, SD-WAN solutions and other devices that are not supported out of the box, and our developers need real devices, running the right versions and configurations, to build and test device clients. You will make sure the lab and the devices behind it are ready, secure and up to date, so developers can deliver their projects without waiting for equipment or environments.
