They have a large presence internationally, and are continuing to expand and grow their North American presence. The North American group has consistently grown through various large carrier contracts (Example: AT&T FirstNet) and they are quickly approaching the deployment of new hardware/software and applications which is driving the need to add to the team. Etherstack is currently looking to expand the team at their Dallas location to add a Sr. Telecomm Systems Administrator to support the deployment/"Go-Live" of their hardware/applications (Interworking function) at an increased scale. The Systems/Network Admin will be a core member of their 24/7/365 Operations team to provide Tier 3 layer support for networking and IT administration for ECS (Emergency Communication Service).

Proactively monitor systems, 4. Assess performance and perform upgrades, 5. Maintain and create SOP's for responses and troubleshooting, maintain/administer accounts, test/deploy software, etc.. The day to day and variation of duties will be heavier on responsiveness to the Go-Live in the start.

Bachelor's degree in a field related to IT, computer science, or telecommunications. (Relevant years of experience will suffice as well)2. Juniper Engineer level certification in both Routing and Switching (JNCIP) and Network Security (JNCIP-SEC).
