60 Gray Systems Administrator Jobs Hiring Near You

Description
Gray Analytics is seeking a skilled DevSecOps Engineer to join our team supporting the Tactical Innovation and Experimentation Laboratory (TIEL) program, with a strong focus on automation, security integration, and operational excellence within DoD environments. The ideal candidate will have a passion for designing, implementing, and maintaining secure, resilient infrastructure and CI/CD pipelines that enable rapid, reliable software delivery. This position requires someone who excels in bridging development, security, and operations disciplines and is committed to embedding security throughout the entire software development lifecycle.
The DevSecOps Engineer will serve as a key technical contributor on a collaborative DevSecOps team, working closely with developers, system administrators, and cybersecurity professionals to bring modern software development techniques to our DoD customers. The engineer will serve as an escalation point for critical and complex issues, perform configuration, integration, and testing of products, assist with developing and documenting work processes, and mentor other team members.
This role is primarily on-site and involves working on systems of varying classification levels across both online and offline (air-gapped) networks. The candidate will perform tasks on both physical and virtual Linux and Windows systems and will support the maintenance of the TIEL's Authority to Operate (ATO).
