DevOps Engineer; Mid TS​/SCI

Purpose and Impact

Amentum is searching for a Dev Ops Engineer to join our team in Arlington, VA. You will be working in support of a DoW Special Programs customer developing a new application in AWS Gov Cloud. The mission is to modernize and sustain a secure, web-based platform that consolidates critical government workflows, enabling automated data management, role-based access control, and multi-level security capabilities in support of national security operations.

The Dev Ops Engineer is responsible for owning the full platform lifecycle (infrastructure-as-code, CI/CD pipeline operations, environment stability, security posture, and incident response). You will deploy and configure services using AWS-native tooling, enforce change control discipline, and ensure the platform meets DoD IL4/IL5 compliance requirements at all times.

Work is typically performed, Monday through Friday 8-hour days onsite. Flexibility within a 2-week pay period to reach 80 hours.

• Design, deploy, operate, patch, and maintain AWS Gov Cloud infrastructure supporting a production web application.
• Own all Infrastructure-as-Code using Cloud Formation and CDK with disciplined version-controlled change management (no manual console modifications in production).
• Build and maintain end-to-end CI/CD pipelines covering build, test, artifact promotion, deployment approvals, and release documentation.
• Implement and maintain private networking patterns including VPC segmentation, Private Link, and deny-by-default egress controls.
• Enforce least-privilege access across all environment components and support NIPR/SIPR connectivity requirements as applicable.
• Integrate security practices throughout the Dev Ops pipeline, automating security testing, scanning, and compliance checks.

• Establish and maintain continuous monitoring of application and infrastructure security.
• Coordinate with the Information Systems Security Engineer on ATO evidence collection, POA&M inputs, and continuous monitoring obligations.
• Respond to incidents, conduct root cause analysis, and implement corrective actions with full documentation.
• Maintain complete operational documentation including architecture diagrams, runbooks, and SOPs.
• Operate with appreciable latitude in developing methodology and presenting solutions to problems.

• Minimum of 5 years of experience collectively with the following:
• Operate and manage production workloads in AWS Gov Cloud or equivalent FedRAMP High / DoD IL4/IL5 regulated environment.
• Build and maintain Infrastructure-as-Code using Cloud Formation and/or CDK with auditable change control.
• Design and operate CI/CD pipelines with artifact management, deployment approvals, and rollback procedures.

• Integrate security practices, tools, and measures into the full Dev Ops pipeline.
• Automate security testing, scanning, and compliance checks throughout the development lifecycle.
• Implement automated security controls including static code analysis, DAST, container scanning, and vulnerability assessment.
