We are excited to be expanding our staff due to our growth and are looking to add a Cloud Security Engineer to our Security Operations team! Cyber Sheath integrates compliance and threat mitigation efforts and eliminates redundant security practices that don't improve and, in fact, may weaken an organization's security posture.

Our professionals tell clients where to stop spending, where to invest, and how to take what they are already doing and integrate it in a way that delivers improved security.

Successful candidates for Cyber Sheath are self-motivated, think out-of-the-box, work, and solve issues independently. Additionally, our most successful people are self-starters and willing to put on many hats in order to succeed. Cyber Sheath is fast‑growing and seeks candidates who want to be part of our upward trajectory.
