About the role: PMAT is seeking a Senior DevSecOps Engineer (Systems Engineer – Level III) to support the engineering and integration of mission-critical software capabilities across containerized, virtual-machine, cloud-based, and PaaS environments. In this role, you’ll work across complex DoD environments and multiple security domains, supporting secure software delivery, DevSecOps pipelines, systems interoperability, and capabilities designed to operate in challenging DDIL, afloat, and ashore environments.

Responsibilities:

• Support full-lifecycle software development across containerized, virtual-machine, and cloud-basedarchitectures.
• Support software engineering and delivery across Unclassified, Secret,andTop Secretsecurity domains.
• Configure and integrate automated security testing tools within CI/CD pipelines, including SAST, DAST, SCA, and container scanning.
