DevSecOps Engineer, Senior Jobs

Senior Dev Sec Ops  Engineer

Modernizing digital infrastructure in classified environments demands engineers who can build secure enterprise platforms, operate them reliably, and elevate the teams that depend on them. As a Senior Dev Sec Ops  Engineer, you will design, deploy, and troubleshoot containerized systems in air-gapped environments, develop and optimize production CI/CD pipelines, author and refine Infrastructure-as-Code, and embed security, observability, and reliability into every layer of the delivery stack.

You'll serve as a technical anchor for a cloud-focused Dev Ops team supporting the DoW, combining hands-on engineering expertise with a deliberate mentorship mission. You will coach active-duty military personnel and government civilians, lead technical exchanges and labs, and strengthen the organization's ability to operate critical systems independently and sustainably. You will also help drive early-stage artificial intelligence (AI) adoption, including prototyping, evaluating AI-enabled capabilities, and responsibly applying AI/ML tooling within classified constraints.

Your work will shape how the organization leverages automation, analytics, and modern platform engineering practices in highly restricted environments. Operate at the intersection of Kubernetes, cloud-native architectures, enterprise automation, and emerging AI technologies-while helping develop the next generation of technical operators. Grow your skills at the leading edge of innovation. Join us. The world can't wait.
