Senior Systems Administrator​/ IT Engineer

Role Overview

Velaura AI is seeking an experienced Senior Systems Administrator / IT Engineer to help administer, secure, and continuously improve our enterprise infrastructure while also providing Tier 2/3 desktop engineering support for our end-user computing environment.

This is a hands-on infrastructure engineering role with primary responsibility for enterprise systems administration, Linux servers, virtualization, cloud infrastructure, networking, identity management, enterprise storage, backup, endpoint management, automation, and cybersecurity.
