Job Description

Works with a cross-functional team to solve complex technical and cybersecurity challenges across a broad range of technologies (Servers, Storage, Network, and SAN) while delivering secure Cloud Services solutions to federal customers.

The Federal Cloud ISSO will serve as a key member of the SecOps Engineering function, responsible for ensuring the security, compliance, and operational effectiveness of classified cloud environments. This role has direct responsibility for Tenable (Tenable.sc / Nessus) vulnerability scanning operations within an air-gapped architecture, supporting ATO/RMF compliance, continuous monitoring, and audit readiness.
